Boat Plans Nz | Cape to Rio Race Starts Tomorrow

,

Boat Plans Nz


It has been a long slog to get here and, strange as it may seem, even now I am not sure where "here" is. We need to be on the start line in Table Bay at 14h00 South African Time (UTC+2) and have been working toward that goal for a year. Now that we are almost there time-wise, we have had all sorts of issues popping up to try to trip us and prevent our participation. Each time that we side-step an issue, another appears in its place.

These are not problems that are directly related to the boat, neither are they related to most of the crew. I cant say what they are but they have been a major distraction in our preparations, detouring our efforts and moving our focus from much needed work into stuff that really should not be on our minds at this stage of preparations. These issues sap energy and drain enthusiasm. It takes effort to maintain optimism, which is normally self-fortifying.

We expect to be on the start line tomorrow and will be deeply disappointed if we should be prevented from going. Only time will tell whether or not we will be there. Watch for the yellow boat if you are able to watch it live, or maybe recorded live (whatever that means).

From here on I will not be posting on this blog live until after the race is over and I return to USA. I will be sending email updates to my wife, Dehlia. She will be posting on the blog but it will probably be without photos. Our Internet connections via satellite phone will be too slow to transfer photo files. If we have something really special to show then we may make an exception.

So please follow us via the tracking link on the race website at http://cape2rio2014.com. This is not a clickable link, so please copy and paste into your browsers address window.

Boat Plans Canada | Didi 950 Build Started

,

Boat Plans Canada


Michael Vermeersch of Ohio commissioned the Didi 950 design and has now started construction of his boat. He is building from a pre-cut plywood kit that was supplied by Chesapeake Light Craft in Annapolis. The kit arrived as 61 sheets of plywood with all components accurately cut by CNC router and packed on 2 pallets.

Michael reports that he is progressing well with the assembly of the backbone and bulkheads and that everything is fitting together beautifully. A few more bulkheads to go, then he will be ready to start setting up on the building stocks.

Michael with wife Pat & daughter Catherine.
Since adding this design to our stock design list, another three boats have been started. They are in Australia, Greece and Latvia.

The Didi 950 is drawn to the Class 950 Rule and detailed for building by the radius chine plywood construction method. It can be built from plans only or from a kit. Kits are currently available in USA but can be supplied by most of our international kit suppliers as well. Enquire with the supplier in your area and I will send the files to them for pricing. Note that for USA you must order from us, you cannot order it directly from Chesapeake Light Craft.

Boat Plans Aluminium | Long Distance in a Bigger Boat

,

Boat Plans Aluminium


My last post was about people going long distance in small boats and most of my readers know that I am soon to go long distance in a slightly bigger boat. This will be on the Didi 38 "Black Cat".

She is well on the way to being ready, with smaller items like installation of new electronics going on and the major still outstanding items being to tune the rig and test the new sails (which have still to be delivered). She is looking awesome, after a full repaint and new graphics. This 18-year old lady is looking young again.

"Black Cat" with her new paint & graphics.
Preparation of "Black Cat" for her next adventure has been a lengthy process but a worthwhile one. It was unfortunately extended by 2 weeks due to damage sustained at Royal Cape Yacht Club during a gale just after she was relaunched when the repaint had been completed. Cape Town is well known for furious winds and this one apparently gusted to 75 knots in the yacht basin. Some mooring chains holding the marinas broke and "Black Cat" was in the unfortunate position of serving as the meat in a steel sandwich, not good for a plywood boat.

My navigator for this race is Dave Immelman, nicknamed Wavy. Dave has been in charge of the preparations and has done a great job of it. That includes getting the extra work done that resulted from poor "Black Cat" getting squeezed tighter than any lady in a corset. She has been freed, repaired, repainted (again), given the OK by the doctor (scrutineer) and is raring to go.
New Cat logo on port side. Starboard has the butt end.
 This is a boys adventure on which we are embarking. As in 1996 and 2000, "Black Cat" will be the only lady enjoying it with us. That said, we would not be doing it without the support of the other ladies in the lives of all of the crew, namely wives, mothers, daughters and others. They tolerate our passion for boats, adventures and ocean crossings. Maybe some of them look forward to our departure to get us out of their hair, I dont know. I do know that they will be happy to see us again when we return and we will be equally happy to be greeted by them when our adventure is over. We will return home with another big drawer full of images in our memory banks, memories that cannot be equalled by any travel documentary or computer game, no-matter how good the filming or graphics may be.

For those who have never experienced this, it is a big one to add to your bucket list. Having done it 3 times before, I can say that it will take a big bucket if it is to hold other items that are bigger than this one. But you have to have a strong sense of adventure and not be easily scared. If you dont have those qualities you will be petrified at times, incapacitated by sheer terror while your shipmates are enjoying a great roller coaster ride that goes on for 2-4 weeks (depending on the speed of your chosen boat), with no chance of getting off the ride.

We have sailed this boat very hard in the past and the new go-fast goodies on her will help us to do so again. We sail her safely but we do so sometimes at very high speed, with lots of spray flying by and mixed in with flying fish, squid, albatross  and even the occasional sword fish. "The Cat" enjoys it and allows us to enjoy it with her.

Boat Plans Australia | Our Cape to Rio Race Wrap up

,

Boat Plans Australia


First off I want to say thank you to all friends, family and supporters for all of the good wishes that have poured in following our experiences in the Cape to Rio Race the past few days. The five crew of "Black Cat" are all very grateful for the assistance received. As is always the case, stories have varied depending on the source and they have no doubt expanded with the telling and retelling. I will tell it from the very personal point of view of being right there in the middle of the action.

The weather briefing two days before the race start told us there there was bad weather expected and their advice was to sail due west as fast as possible to get through the system to the high that would follow. That would give us SW winds that would turn S then SE. With my navigator, Dave (Wavy) Immelman, we decided to follow that advice as the most logical route. The weatherman warned about being in the SW quadrant of the storm that would follow a day or two later.

The race got off to a good start in light breezes, the course taking us around the perimeter of Table Bay. This was a good indicator for us of our chances of placing well in the race because we were very quick, and staying in the lead group of 4 smaller boats trailing the 3 big guns that led the fleet. Our group opened up a large gap from the others behind us.

We sailed through the first night in gradually strengthening wind that gave squalls of 20-25 knots. Around daybreak the squalls started to intensify and broke through 30 knots with 18-20 knots between them. Feeling a bit over-powered in the squalls we were reefing the mainsail when a squall of somewhat over 40 knots hit us. We were now entering the SW winds behind the front, so I changed from our westerly course to a NW heading, taking pressure off the sails. Despite that, the wind over the deck increased, with gusts of over 50 knots that shredded our new carbon jib, leaving us under main only.

While changing from the #1 jib to the smaller #3, we were running before and gaining speed rapidly. Wavy was standing on the foredeck at the forestay, hauling down the tatters of the jib when we took off down a wave, accelerating to 22 knots. The waves were very short and steep and we ran straight into the back of the next wave, washing Wavy aft against the shrouds, spraining his ankle and inflating his automatic life-jacket. At the same time the tiller went sloppy in my hands. Although "Black Cat" was running fast and straight down the wave she was doing it on her own, we had no steering.

We dropped all sail and elected to sit out the worsening conditions before setting up a jury rudder to take us back to Cape Town. "Black Cat" was comfortable and in no danger. While we waited we saw the German entry "Iskareen" sail past from behind. We thought that this very fast boat was ahead of us so it came as a surprise to see them come past from well astern.

The wind and sea moderated quite quickly from that first storm and we put our minds to making a jury rudder from lazarette floor boards. Sean Collins went over onto the sugar-scoop to screw and strap it to the stub of the rudder that remained below the pintels. It worked reasonably but we treated it gingerly for fear of breaking it. We motored on a heading for Cape Town but as the day progressed the conditions slowly deteriorated as a second storm started to move in. I saw that we were not going to lay Cape Town so elected to rather head for the closer and easier Saldanha Bay.

As evening approached this storm grew progressively more violent. We were in the SW quadrant of the storm about which the weatherman had warned us. We had no desire to be in that position at that time but we had no choice in the matter. Fate had placed us there and we could only do our best to cope with the situation as it developed.

Around dusk there was a massive bang, a noise that sounded like the boat being ripped apart. Sean had shouted a warning from the cockpit that I cant repeat in present company but none of us heard it. Suddenly we were upside down and the cabin was filled with flying bodies and objects that were loose in the cabin and also those that were inside closed and latched lockers. I had been sleeping on the starboard saloon settee and had only a few seconds earlier stood up to walk aft to the cockpit. I was still in the saloon and was hit on my face and top of my head by unidentified flying debris, leaving me with minor cuts and a black eye.

The noise of this impact was so great and our up-turned position so alarming that I thought that the keel had come off. I was on the cabin roof and looked up at the bilge, all cabin soles having fallen out. I saw no gaping hole as I expected but shouted "Everybody out!!", still thinking that we had no keel. This all happened in a few seconds, then suddenly she was upright again and I knew that we still had a keel. We were left with an awful mess of food packages, cabin sole panels, tumblers, containers and anything else that managed to find its way out of its allotted place. And there was water everywhere. There had been some in the bilge but a lot more had come in through the companion hatch and a hole that we had no yet identified.

With no instruction from anyone this very capable crew automatically set about sorting out the chaos, first picking up anything that could block the bilge pumps before starting to pump out the water. The day fridge, which had been bolted into the saloon table, had relocated itself to the settee on which I had been lying only 30 seconds earlier. Three fire extinguishers, mounted in brackets from which they are removed vertically, all fell out when we were inverted and flew across to the starboard side of the cabin. Only two of the five onboard were in steel straps with locking mechanisms that held them firmly in place, the other three fell out and became lethal missiles.

Next we discovered what the hole was that had appeared in the deck. During the inversion process the tail of the mainsheet went over the side and attached itself to the propeller and wound itself up to the point that it stopped the diesel motor. It had so much tension in it that the force downward on the upper guardrail wire punched the nearest stanchion through the 12mm plywood deck. That left a hole about 75mm diameter into the locker below, where my clothes were. From there the water spread itself all over the starboard aft cabin, soaking everything that Wavy and I had in that cabin. That was all of our clothes, bedding, camera bags etc.

Of more consequence, the volume of water that came into the boat spread itself over the chart table, the lid of which had ripped right off, and into the electrical panel and electronics. The two satellite phones and main VHF radio were drowned, leaving us with only a hand-held VHF of limited range with which to communicate. Smelling smoke, Wavy opened the electrical panel to see smoke coming out but it didnt develop into a fire.

Time stands still in these situations. I have no idea how long it took us to clean up the boat but she was back to a semblance of ship-shape before too long. The hole in the deck was plugged as well as possible with some muti that we had brought onboard the day before the race start.

In the midst of all this Sean came down from the cockpit and described what had happened. From inside the boat we had no idea, it was just massive noise and upside-downness.

Sean, a surfer like me, says that he suddenly felt the same feeling as when caught inside the impact zone of a big surf break, where you have no way of escaping the beating that is about to be dealt to you and you just have to take it on the head and cope with it. He did not see the wave coming but became aware of it as it loomed over the boat. It was very large and broke as a hollow tubing wave completely enveloping "Black Cat". She rose up the face of the wave, rotating as she rose until she was hanging from the roof of the tube. Then she fell or was thrown down the face of the wave with the mast going in first. The crash that I heard inside the boat must have been the cabin and deck hitting the water. While this was happening I also looked into the cockpit for Sean and he was hanging from a winch or whatever he had been able to grab as the wave reared up. I required that all crew be hooked on with safety harnesses before going on deck but Sean was hanging on so tight that his harness had no work to do.

This wave was much bigger and more violent than any others we had felt or seen. If that one could clobber us there may also be others, so we streamed warps from the bow and deployed the storm jib as a sea anchor to try to hold her bow-on to the waves. These did not seem to help much because the underwater current seemed to be pretty much the same speed as our drift. We didnt get her to lie more than about 20-25 degrees from broadside-on to the waves but it seemed to be enough to ease the motion a bit and cause other breaking waves to roll past the port quarter instead of hitting us amidships.

The worsening storm and loss of major communications prompted us to ask Cape Town Radio to put out a Pan-Pan message on our behalf to warn of our location in the shipping lane and to ask for the NSRI (National Sea Rescue Institute) to be called to our assistance. We advised that we were in no immediate danger but would appreciate assistance when it could be provided. We switched on the EPIRB to give a signal for rescue services to home in on. We had AIS onboard but it had flooded along with the other instruments at the nav table.

Initially the assistance came in the form of the fishing vessel "Miriam Makeba" heading our way. When they were still a few miles away the navy frigate SAS Isandlwana took over control of the widespread rescue efforts and released the fishing vessel to continue fishing. As the frigate approached in the rain they asked us to send up a flare, then another, to help them to locate us. Once they had located us we confirmed that we were in no immediate danger and they headed off to take care of people and boats that were in much more serious situations.

In the morning conditions again subsided. Wavy went over the side in his diving gear to free the mainsheet from the prop, which allowed us to restart the motor. At the same time he swam the length of the underbody to check for damage or other problems. A new and improved version of the jury rudder was fabricated from more plywood cannibalised from the lazarette and we continued on our journey toward Saldanha Bay at 4-5 knots under our own power. We were well set to reach there during the night.

Early afternoon the NSRI Rescue 3 arrived from Cape Town. They offered us the choice of continuing under our own steam to Saldanha Bay or accepting their tow back to Cape Town. Proceeding to Saldanha Bay presented logistical problems for crew and boat, so we took the tow and headed for Cape Town at 10 knots.

Manoeuvring into the RCYC basin proved to be more difficult than anticipated because the jury rudder boards added to the starboard side of the rudder severely limited rudder movement in that direction. Add a pomping SE gale and we sorely needed the welcoming hands on the dock to catch us as we came in at rather high speed and with negligible control.

Now "Black Cat" is safely back in port but she has some more patching to be done to her. This is for the hole in the deck from the stanchion and for the spot where her bow kissed the marina rather harder than necessary on our return.

My big question out of all of this was "Why did the rudder break?". It had a solid Iroko spine nearly 100mm thick and 150mm wide, extending top to bottom, with plywood fairing to leading and trailing edges. That is a massive piece of timber that can easily support a large car and really should not have been broken by a 22 knot surf. The answer came from the owner, Adrian Pearson. He told me that when "Black Cat" was squeezed between the steel RCYC marinas a few weeks ago when the mooring chains broke, it was not only the hull and keel that were damaged. He said that the rudder was also "graunched". If that is so, it may have started a fracture of the rudder spine that culminated in the blade shearing off at high speed.

We are all very disappointed that our race had to end this way. We were going so well and must have been in with a reasonable chance for a top result. Unfortunately, we will now never know. We are just glad to be back on land safely and are very grateful to NSRI and the crew of Rescue 3 for their part in it, as well as the "Miriam Makeba" and SAS Isandlwana.

I also want to thank the crew of "Black Cat" for being such great and capable shipmates, always ready to do the right thing and with a smile.

Adrian Pearson (owner)
Dave (Wavy) Immelman (Navigator)
Sean (Buttercup) Collins
Gavin (Doris) Muller

And a big thank you must also go to our  Didi 38 "Black Cat". She took a hammering on our behalf and came through with negligible structural damage.

Boat Plans At Mystic Seaport | Long Distance in Small Boats

,

Boat Plans At Mystic Seaport


For as long as man has been on this gorgeous blue planet of ours he has sought to find adventure wherever he can. There have always been those who simply have to see what is over that next hill. When we all know what is over that next hill then the adventure becomes going over that next hill in some way that has never been done before. It has probably not been done that way before because it is just too big a challenge for most people to consider trying.

That insurmountable challenge is the best of reasons for some people to try it anyway, to prove that it actually can be done and to prove themselves to themselves. In the process of succeeding they also prove themselves to the rest of mankind. Some of mankind thinks it exceedingly silly to do these things and will be eternally critical of those who try. They have no adventurous spirit themselves and would never attempt anything that they consider the least bit risky or dangerous. Some of them become bureaucrats to control others or they encourage bureaucrats to stop the adventurers from being adventurous, a misguided attempt to protect them from themselves.

I have written here before about one such adventurous person, Anthony Steward. He is the only person to have sailed around the world in an open boat. I am fortunate that Anthony selected my TLC 19 hull as the basis for his open boat voyage. Everyone thought that he was crazy in his quest but he was permitted to do it. That is how it should be.

Now I am working on a design for another person who has the aim of circumnavigating the globe in a different way from how everyone else has done it before. His name is Davey du Plessis and he plans to peddle his way around the world. My job is to provide to him the boat that I believe will give him his best chance for success. At the same time, it has to be economical to construct because he is on a tight budget for the voyage.

The result is a multi-chine plywood craft of approximately 23ft length overall. The hull is of fairly classic form that will also make an excellent pulling boat. It has a fine bow at waterline for wave penetration and a fine stern for low drag at the low speeds that can be expected under long term human power.
Hull of the Ocean Peddle Boat for Davey du Plessis.
The superstructure is also multi-chine plywood, so that it can be quickly and easily built using stitch-&-glue building methods. It is a closed boat for maximum protection from the elements but with the ability to open up large surfaces of the central cockpit area to allow air to flow through when needed. This also increases the safety tremendously in rough conditions, making her essentially self-righting if all of the gear is properly stowed and secured.
Basic 3D model of hull and deck.
The model above is very basic, it doesnt show the details of the deck, like windows, opening panels, hatches, solar panels etc, which are detailed into the building drawings.

The whole concept is conceived to make a seaworthy boat. It is not designed for speed, it is designed for cruising slowly under human power, aided where possible by wind, wave and current.

What about the crazy man who will live long term inside this eggshell? Maybe Davey is not as crazy as you think or maybe he is more crazy than you think, I doubt that he knows for sure. He is no doubt less crazy than Anthony Steward because Davey has chosen to have a boat that will give him shelter for his long voyage. Does Davey du Plessis have the legs for this voyage? You can bet that he does, he has ridden a bicycle the length of Africa, from Cairo to Cape Town. Davey is an adventurer and I applaud him for it.

Daveys boat will be built in Knysna on the South African South Coast. The builder is his uncle, Tertius du Plessis, who has previously built one of my designs, a Didi 34.  I doubt that I will even get to see Daveys boat because his route is unlikely to pass anywhere near to me in USA.

I will add this boat to my website when the design is complete. I will no doubt offer it as an open pulling boat but it is possible that there are others who would also like to build it as a trans-ocean rowboat or peddleboat.

Boat Plans Catamaran | Cape to Rio 2014 Black Cat Preparations

,

Boat Plans Catamaran


Start day for Cape to Rio 2014 draws near, now only 4 days away. Preparation of our radius chine plywood Didi 38 "Black Cat" continues. Most of the big jobs have been completed but somehow the list of smaller ones never ends.

Earlier this week we were able to go sailing for a few hours to try some of the new sails, all made by the North Sails Cape Town loft. The mainsail and jib are both carbon and are a real treat to use. They set beautifully to the designed shape and are very stable. There was a bit of swell running and I found the sails to be easier to helm to than the previous laminated Dacron sails, with the sail shape not changing from surging in the swell as happens with a softer sail.
North carbon jib. Sexy see-through clothing.
Photographic conditions were not great, so these are not the best of photos. They show the new carbon mainsail and jib. For purposes of optimising our IRC rating for the race, sail area has been reduced in the headsails, with our big (and very old) Genoas with large overlap gone for good, replaced by a jib that hardly overlaps the mast, does not foul the spreaders or shrouds and is very quick to tack. It also sheets very close and allows "Black Cat" to now sail very close to the wind. This will be a great sail any time that we have to go to windward.
North carbon mainsail
The reduction in headsail area is somewhat compensated by the larger roach of the new mainsail. The larger roach and stiffer fabric means that there is a lot more conflict between backstay and mainsail, so she now has a flicker on the backstay, which you can see on the photos, to lift the top of the backstay away from the sail to allow it to pass through.

The new Code zero has massive area and showed itself to be surprisingly close-winded also, able to sheet to a very close reach, almost a beat. With large shoulders, it is also very stable and much easier to steer to than a conventional spinnaker. This sail rates as an asymmetrical spinnaker rather than a Genoa, allowing us to sail to windward with a spinnaker in light to moderate breezes.

I have written previously about some of our crew for this race. Without bio info from the other two, here is as much info as I can give for them from my own knowledge.

Dave Immelman is the normal skipper of "Black Cat" and has graciously moved into the navigator slot to allow me to come in as skipper. Dave is very experienced in competitive sailing, having crewed in the South African "Shosholoza" Americas Cup Team, a Volvo Ocean Race campaign and extensive racing in South Africa, UK and the Med. Dave is very tough as well, having rowed 3000 miles single-handed across the North Atlantic Ocean. It was intended to be a double-handed voyage but his partner took ill and was taken off the boat very soon after the start and Dave decided to continue by himself.  We will have many interesting stories to swap on this next voyage. Dave is married to Susan, an award-winning seafood chef. They have a daughter of 5 and another arriving while we are mid-Atlantic.
Dave Immelman at the time of his rowing voyage.
Adrian Pearson is the owner of "Black Cat". He was my partner in her from during construction through to 2000, when he took over full ownership. Adrian loves to sail on her but does not often skipper her, preferring to hand over that job to someone with more experience. Not that Adrian lacks ocean experience, he was in my crew for the 1996 and 2000 Cape to Rio Races, crewed on her for the return from Rio in 2000 and did many coastal regattas and races with me around the Cape of Good Hope. Adrian is a retailer in Johannesburg, co-owner of a large grocery store.  He is currently unattached and has two sons and a daughter.

Dont forget that you will be able to track our progress across the Atlantic. Go to the official race website Cape to Rio 2014 and click on the tracking link at upper right of the screen.

I should be able to make one more post before we sail away. I hope to make an occasional post while on the water but cant guarantee that it will happen. Our Internet connection will be via costly satellite phones so has to be used sparingly. We will have a separate boat blog for the race and I will post the address of that blog in my next post here.
