      Beautiful!

      Make the sail and stuff about 1 ounce, plug in a fudge factor and I get a topside displacement of 10 ounces. I'm on the two-motor SD for this thing, Scott!

        • Reaaaaly impressive!! Did you have to rescribe the details or did that hull come out just like this?

              Poped out just like this. The first shot out of the mould always seems to have a few blemishes in the gel coat; some small places where the gel coat beads up on the surface of the mould. That usually goes away for subsequent shots. I'm quite happy with it so far.

              • This is the first hull; bottom and top together. There were a few issues with the rear plane slots and a section of the stern where the rubber glove bulged a few mm. Other than that its OK.

                This is the second hull waiting to cure. I'll leave it in the mould for four or five days before lifting it out.

                • The rear section just wasn't right so I stood the plug in some rubber and made a new mould of the rear section. Thus:

                  This is the gell coat.

                  Once it goes off I'll lay in some fine cloth and start to build up the thickness. Then its a quick trim around the edges and joining the two halves in the mould. Hopefully this will be better than the original which was far too difficult to lay up correctly.

                  • I see how the horizontally split hull halves narrow at the stern, making it hell to get in there with your ape-like fingers to do any useful lay-up work. Hence this change of your hull lay-up methodology.

                    So -- correct me if I get this wrong, Scott -- you are first producing a GRP stern parts from a more sensibly, vertically split, stern tool; inserting that stern piece into the after end of the lower hull tool half; and bonding it with the hull lay-up? This 'insert' producing the radial break at the top of the stern onto which the after end of the upper hull half will butt?

                    (in the voice of Mr. Burns:) "Excellent. Most excellent!"

                    Bob will be here for some training. I'll show him your work. I'll ask him to use the sharp knife as he posts comments.

                    • That's the plan. We should end up with a tidy rear end, at last.

                      • Given that the waterline cut makes the upper and lower hull meeting so acute I'm wondering if I should do the same thing to the bow. Maybe cast the first eight inches or so as one piece and just drop that into the original mould and then add the remaining top section. I'll see how the stern goes before geiing ahead of myself.

                          That may not be a bad idea. Curious to see how this works out with the stern. Keep us posted!

                          • The stern section came out OK. The seam is a little rough but will clean up with some filler and a bit of TLC. This is the rear section placed into the original lower hull mould with the gell coat in place for the new lay up. I think that it will be significantly better than the old version.

                              I see what you're saying about the bow - that idea of making the first 8" or so one piece may not be a bad one. I think about what your eye gets drawn too immediately - the pointy bits, and if there's a big split running 'round the nose, even if it's really well done, you're going to notice it.

                              • I can probably make the seam go away; its just that there is a lot of detail there that might get lost in the process.
