A boat should be dry inside even in heavy weather, and even after having been capsized and pitchpooled. At the same time it is a good thing to have a functioning ventilation system. Fresh air is a good thing.
1974 while attempting to round Cape Horn, I and the 20 feet boat I had built in my mothers basement the boat was capsized. A weak later in some of the strongest winds I have ever experienced she was pitchpooled. Water had entered through the ventilaters and created a mess. To avoid a repeat I figured out a system that would keep the boat dry. Two years later working with multihull designer Dick Newick on Marthas Vineyard I built my first system. It was provisional, just two hoses I put up when the waves started to break. On the boat I built 76 – 79 I made a permanent system, a aluminumtube from the deck to the bottom of the boat.
On Amfibie -Bris 85 – 89 I added a transverse duct so that intake an outlet was diametrically opposite.
On the yellow boat that I 2011 sailed to Martinique in I added a trap to the Doradebox thuse all the incoming air separated from water went into the cabin.
Now on Exlex Minor there is no deckhouse there is also stearing ropes that passes through the bulkhead with the two ducts of incoming and outgoing air and the door rotating around a horizontal axis is also there to add to the complexity in the region. This makes thinking necessary. However by slowly approaching the problem I now see a way. To simplify the problem, I have started with the given, a hole in the boulkhead and later I will do holes for the cowl vents in the deck. Then I will connect them with ducts that do not crossing each other.
Below some pictures.
There is plenty to do Christmas and New year will be spent working on the boat. If you have any money left please donate to my project. It is good for mankind with smal safe shallow draft ocean going boats propelled by sail and oar.
Tonight I have with the help of Stefan and Håkan laminated the outside of the deck.
I asked Stefan if he could give me a hand. I have 30 minutes he said after that I must go to a consert. Work took much longer after over an hour he had to leave. Lyckily Håkan turned up and stayed to the end, thuse rescuing me. It was filling the gaps I had cut to be abel to bend the top part of the deck that was the problem. The gaps used upp a lot more NM-epoxy thickend with silica than I had estimated. I had never done that before and sometimes new thing takes longer than planned. In the end thanks to my friends evrything went well. I am now ready to start designing and build the important ventilation system. Boats do capsize and pitchpoole. Whats happening in the Golden Globe race 2018 amply demonstrates that stormy weather do capsize boats that sails in high latitudes and causes a lot of damage. I belive that only a small boat well designed can come out of bad weather with no damage.
“There’s a Hole in My Bucket” is a children’s song, based on a dialogue between two characters, called Henry and Liza, about a leaky bucket. The song describes a deadlock situation: Henry has a leaky bucket, and Liza tells him to repair it. To fix the leaky bucket, he needs straw. To cut the straw, he needs an axe. To sharpen the axe, he needs to wet the sharpening stone. To wet the stone, he needs water. But to fetch water, he needs the bucket, which has a hole in it. Harry Belafonte made a famous record of it in 1960 well worth listening to.
After finishing the hull and I started to make the lunch boxes, but before installing them I had to do the ventilation system so I started in my bedroom with the stovage, but before finishing that I had to do the ventilation system but before doing that I had to do the deck, but before doing the deck I had to do the mastholder.
I have also started on the coamings for the two hatches.
Now the mastholder is done ready to be installed, the deck is laminated on the inside ready to be put on, in other words the deadlock is broken. Soon there will be some progress.
Today 18:30 we started to mix the NM-elastic epoxy. Helping me were Håkan Stefan Peter and Petter. All went very well although my original plan had to be changed for a better one suggested by Petter. One should always chose helpers that are smarter than oneself.
Below are some pictures taken by Håkan. The reason you cannot see him is that he is behind the camera.
I like also to thank Lagermetall in Örebro who supplied the bronze plate and Wevik Maskin AB here in Västervik who bent the palte to shape.
Today was spent on improvements. The results was very satisfying. I was able to reduce the space between the plate and the hull to about 2 – 3 millimeter at the worst places. Yesterday it worst place was 9 millimeter. To achive it I drilled holes through the hull and tightend them considerabel the 12 mm plate yealded and the gap closed.
Below two pictures.
This is the dry run. For the real stuff I need 4 or 5 friends and more NM-epoxy. Monday I will start to organise the event. Intill then there is other stuff to take care of.
Today I have been working with the bronze plate from Lagermetall Örebro, bent to a fitting curvature by Wevik Maskin AB here in Västervik.
A lot of holes had to be drilled and some tapped. The plate is to big for my drillpress but by using a mighty sharp drill and get support from a box all went well with the holes and the tapping.
It turned out that the plate was heavier than anticipated 138 instead of 127. The extra kilos will do good rounding Cape Horn.
To get the plate in the right place some reshuffling had to be done. The boat had to be put upside down and rolled away, the heavy plate lifted up towards the cealing. The boat had to be rolled back and put in a very precise position below the plate. The finally the plate had to lowered.
All went very well except for the very last correction, then the boat fell over. A bad thing had happend. The bulkheads got damaged but can be fixed without to much weight gain I hope. No use cry over spilled milk. I continued.
To cheer me up the plate fitted itself in the most beatiful way. Only about 9 mm in the back was there a rather wide gap between the plate and the hull. I belive I can do something about it. We will see.
