Sven Yrvind

13 August 2022 preparing for for filling the bow with high density 2 component polyurethane foam.

I plan to fill the bow with high density 200 kilo per cubic meter expanded two component polyurethane foam. That will increase the strenght of an already strong boat, but thats not the reason I am doing it. The reason is to make the boat clean with no hidden parts behind the centerboard trunk where ...

12 August 2022 The centerboard is in place and works to my fully satisfaction.

The centerboard is now in place and works to my fully satisfaction. I belive it is the best centerboard ever that I have done. There is no fulcrum pin that is difficult to get at. The control lines are fully accesible. Even if the should break the centerboard can be move up or down at will as the ...

11 August 2022 Opening the slot very carefully as not to damage the trunk sides.

Today I have opened the laminated slot with care as not to damage the trunk sides. All went very well. I finished with sandpader on a piece of wood to get the outside laminate in line with the inside of the trunk. If you’re interested in contributing links are below. Swish 0706200550

10 August 2022. Reinforcing the bottom of the CB trunk with 5 more in addition to the 2 yesterday.

The two layers of glassfibre I did yesterday with the boat on even keel is now supplemented with five more 450 gram. It is so much more easy to work with the help of gravity that I suggest that anyone starting to build a boat first figure out how to rotate the boat. Even 40 feet steelboats can be ro...

9 August 2022 Closing the CB slot temporalily to prevent epoxy from enter the trunk when laminating

Next step is to laminate the bottom oc the centerboard trunk and get it attached to the outside laminate. To do that I like the boat to be upside down. That makes the work so much better. But with the boat upside down NM-epoxy will get into the centerboard slot, not a good thing. Therefore I am putt...

Yesterday the centerboard trunk was fixed in lined up position. Today I turned the boat upside down and filled the gaps with Divinycell and thickened NM-epxy.

The centerboard trunk is now in place. Its six degrees of freedom are gone she is now fixed in the relation to the boat. I lined her up as good as I could. I do not think it is ultra important. A boat moving on a wavy ocean is not a symmetrical object. Bonus is me adapting the bycycle light so that ...

Doing fillets and laminate the starbord side of the centerboard trunk. There are many videos on how to do fillets. They tell you to put the thickened epoxy in a bag, cut a corner of it and squise the epoxy into the place then use a tool with the appropriate radius to spread it out. Then use a chisel...

2 August 2022 Cutting the CB in G 11 epoxylaminate. A mistake and a close call on the CB-trunk.

With the mockup as a pattern I draw the shape of the centerboard on the G 11 epoxylaminate. It is very hard and difficult to shape but modern tools like jigsaw blade covered with carbide-tungsten grit made it much more easy than outherwise would have been. Still it was slow work but not difficult. N...

Divinycell sandwich construction is amazing. It gives you strenght, insulation and flotation all at once. Shore a metall boat is strong but you have to insulate it well especially if you intend to sail in high latitudes. Do not let there be any cold spots unless you like to spend a lot of feul to ge...
