Is it essential that the inwale is in one piece or can i use 2 or 3 ??
Im gonna have some problem if i should get it home in one piece after it have been sawed

Bjarne,

You could use 2 pieces, but eventually you would like to glue the gunwales in one piece to the hull rather than in 2 or 3 pieces as this might complicate matters.

If the pieces are shorter than the length of the sheer line (in this case the top end of the plywood), you could join the pieces of wood together using a scarf joint.

This site shows you how to do this:

Another useful site (it is at least for me) is yet another Peter Hyndman site:

(I had especially a look here for more information on how to glue the gunwales, inwale spacers and inwales in place.)

Regards, Joost

You can splice several into one. You can "scarf" them together and will be as strong
as a single piece. Measure thickness. Multiply X6 or 8. Measure and mark from the
end. Do again on the other one to join. Cut bevel across both pieces clamped together. The bevels will match, and then glue them up. Take your time and get
them as close as you can. The joint will be almost invisable to everyone but you!

Thank you for the answer.
I think ill go for the scarf solution, unless i can get it home in one piece. The solution is ofc to rent a trailer

Bjarne

If renting a trailer is not too expensive (and you have to transport the plywood as well I guess), I would personally go for the option of getting the longer wooden parts in one piece. It will save you quite a bit of work: scarf joints on 4 gunwales, 2 inwales, and 2 chine logs.

Joost

The Plywood come with a truck - that i have payed for
Ill try to stamp up a trailer.

One more question, what do "gunwales" mean and where is it on the boat ?
The same go for the "chine logs" ?


Thx

Bjarne

Off to Duck Flat today ... so rushing.

But ...

Best wishes

Thats perfect!
Its exactly what i need - not so many words, just pictures

Thank you!

Good for you. Get camera and take some pic's as ya go. I plan on a GIS
sooner or later for myself too. Coogs

Michael, the inside of the Goat looks very slippery!!!

Howdy,

Nice way to deal with it is the same way we did the PDRacers. I couldnt find he pics on the building thread.

You varnish the cockpit floor normally.

Then mask off the area you want to be non skid. Measure and plan it carefully so it looks nice. Doing the whole bottom looks terrible. A glossy margin around the edges and up the middle of the non skid area looks best

Better to have a 50mm margin round the front and edges and keep it about a foot clear at the back. Also leave a 70mm wide area up the middle.

Probably need two small patches either side of the centrecase.

Mask off. Corners need to be rounded off - so put some tape across the corners, use a tin and a stanley knife (carpet knife) to cut the internal corners round.

Sand ready to varnish ... pay attention close to the tape as it is easy to leave shiny spots by accident. Clean up dust.

Put a normal thick coat of varnish down on the areas (if you have a lot to do you may need to do an area at a time. Then .. the magic.

Sprinkle some coarse grain sugar or salt or epsom salts over the wet varnish. Using a sifter gives an even distribution. Just so there is an even distribution of grains. Just so it starts looking like the grade of nonskid that you would like.

Don't push them into the varnish manually, just let them sit. When done remove the masking tape carefully.

Next day put the boat on its side and rinse away the grains. Clear non-skid.

(I didn't do a good job of rinsing with the first boat I did this to many years ago ... and ended up with an ant invasion .. so be warned!)

If anyone has the pics showing this on the PDRs bookmarked...

Clint,

It could be -- if it were strictly varnish. Instead, it's likely sugared varnish. Just sift some sugar into the final coat of varnish & when it dries... rinse out the sugar, leaving a nice non-slip surface. I used the same technique on the PDR I just built. Works just fine... a sweet solution..... I imagine you could achieve the same results with salt.

OOPS, I see Mik beat me to it.

Less than impressive performance, I'd say, for someone who's almost a full calendar day ahead I have to admit, though, that you gave a far more comprehensive account of the process.
