Is that your strongback? Make sure it is screwed/bolted together firmly. You might want to add some support to keep it from racking. I don't have a great picture, but you can make out the 2x4 diagonal I attached to the bottom.

I plan to reinforce as I go. It's pretty stable as it is, I used OSB in the corners and joints to stiffen it. Made a world of difference. Thanks for the Tip!! :wink:

I didn't make out those osb triangles. Those should be good.

I still need an answer on using the 4" for joining long and stringers panels.
I read through the notes and the lamination schedule but I'm not finding the answer.
I made some progress yesterday. I cut and mounted the motorwell sides to the transom and made the bow mold.
I hope to get all the forms on the strongback this week.

.
What is the question? Stringers do not require any butt block or anything to join the two layers. The seams are offset, you just glue the two layers together.

Thanks Jacques, I assumed one needed to add a strip of glass on the seam.
Is the 4" inch tape correct to use use on frame "G" and the side/bottom panels?

I don't use any tape over the puzzle joints.
The joints will be covered by a good number of fiberglass later.

I don't have a pre cut kit. I'm cutting these out myself. I will simply have butt joints.

Sorry, there is a C21 kit builder that is posting regularly.

For you, same thing for the stringers: the seams are offset and no need for a fiberglass splice BUT for the hull panels, you should use a splice. You need a fiberglass splice. I may mention it in the notes but if I don't, one layer of biaxial tape each side. On the outside, grind the plywood down a little bit to reduce the need for fairing.

Hi Jacques,

I finally got all the frames in place and I'm ready to cut out the hull. I had to put the build on hold for a number of reasons, including my 76 year old Dad have emergency quadruple bypass. On DWG# E226/7 it shows the layout for these pieces. The sides are clear to me but not the bottom panel. Are the curves on the bottom spaced at 2' like the sides or are they all spaced like the bow end (last section) at 1'-11 1/2". Thanks for clearing this up for me.
