This ones for those of ya who do always follow the plans.

I had some difficulty marking out the coming for the southwind the curves just don't seem to match. So does anyone have any suggestions on how to mark out coming pieces to match the hole in the deck?

Thanks,

Tor

which part?

This is not exactly kosher but something that worked for me.

Take a piece of cardboard and lay it over one side and have the edge of it even with the center line of the boat. Reach under it without moving it and mark it with a marker , run the marker along the inside of the wood of the boat. Now repeat the process on the other side and list on the cardboard , left and right sides of the cockpit.

Cut on the line to get rid of the center section ( Open cockpit area of the boat) of the cardboard and extend the marking at the bow an inch or so. Now use the templet to mark out on your plywood the shape of the cockpit , one side at a time..... Trim or cut out the width you want , do this for both sides.

Using clamps fasten that strip to the deck along the cockpit and mark then trim off the excess at the bow portion of the cockpit. At this time it should appear as one piece with the center line of the boat being the same as where you trimmed those ends. Use these strips as templets for the rest of the coaming...... When you have what you want ... epoxy them to the boat.

Do the same thing for the back or stern side of the cockpit.

Thanks chuck,

I like that idea, I'll steal some card off the "bin lids". Such an obvious idea but couldn't see it for the wood...

Matt the curve from the front to the rear I just couldn't get to match the deck. The rear bit is ok 'cause you put a template in.

Thanks

There are templates for both the coaming on the deck. Do you have both?
