<p>I agree that 5200 locks things together. That was my point in mentioning alternative caulks and by "glue" I mistakenly thought you were talking about two-part epoxies or some such. The Dowsil looks like an interesting alternative.</p>

<p>Interesting. Cool. But 5200 is famous for being so permanent you have to saw through any joint to get it apart.</p>
<p></p>
<p>I bought a case of Dowsil 795. It's a silicone caulk not based on acetic acid. I'm not sure why that would be important other than it does not smell like hardware store silicone. It's considered a good salt water marine caulk.</p>
<p></p>
<p>It grips like a starving monkey. Up to a point. But you can get stuff apart if you really need to. With 3M 5200 I don't…</p>

<p>Sort of kind of. My Tatman kit boat went together with SPAX screws and 3M 5200. The 5200 isn't exactly a glue, but it's categorized as a permanent caulk. Considering the way I use the boat, if I had it to do over again, I would use a less aggressive caulk, perhaps something like 3M 4200.</p>

<p>I've been leaning this way for years. The last few boats I've made (not framed) incorporated parts of this idea. I haven't built a boat entirely that way yet. But I've done enough of it to see it would indeed work. The various major boat parts do become easier to remove and replace.</p>

<p>If a guy was planning to build this way from the getgo he or she might want to double the height and thickness of the chine strip, which isn't all that hard--not if you make it a built-up gluelam with 1/4" inch ash or white oak strips. I build all my gunwales that way now. Glued (that part would be glued) together with TightbondIII.</p>
<p>But a gluelam chine strip wouldn't be a requirement. You could, I think, build any framed boat completely as it has always been built. But swap ring shank nails for torx screws. And lots of them. And marine grade caulk for glue.</p>
<p></p>
<p>And then a busted side panel wouldn't be so devilishly hard to replace.</p>
