| Rob will probably want to kill me for suggesting this, however ..

| I think some builders would benefit from kit support. That is to say. not the usual developed hulls which take some work to move around the country or further. But as a replacement to the plywood idea, infused foam panels in whatever dimension works, be it 8x4, 10x5 etc.

Imho, having done wet layup, tabbing, sanding, et. al., I was attracted to the promise of the opposite of ply construction.

The Idea that one can flat infuse almost everything, and simple box mold the rest, with fit together self aligning male female joints, almost never touch or be exposed to epoxy, or, worse, is just awesome. No tabbing! No sanding? No touching glue!

I can see no good down the path of ply construction. You still have to glass both sides, at wet layup ratios of expensive glue. In awkward positions and varying finishes and quality.

So I honestly ask, what can you see being gained down this path?

As to kit support, to me, kits mean paying more, and doing less.

I think its entirely reasonable to help a builder find a composite company who will fashion a HP to some level of completeness, and probably said company will be very happy to get paid to learn an awesome technique.

| The differences would be things like prepped tabs and windows are a bit difficult to pre build into the panels.

In theory, a kit might not need tabs.

If one could find a composites company that will infuse and flat pack almost the whole boat to the builder, on demand, for final assembly, as well as glue tubes or whatever might be needed to final assemble the boat, that is an awesome kit, right?

Windows in my aviation experience are pretty simple. One routes out patterns on both sides, and removes some foam, slides in a lexan window from one side, and tabs in three sides to hold it. I don't know if that might work in boats. I think opening windows are needed on boats.

| It would perhaps be more like a plywood boat, cut the sheets, glue the parts together.

Why not just glue the parts together from a flat pack?

| just an idea for which the 40 is probably better disposed than most.

A flat pack might also fit a 50, or a 60?
