    I've done a couple wood boat restorations a 25' lyman (clinker lapstrake) and a 12' 1912 consolidated two station tender. I restored both using tradional methods for the hull however I did use west-system on the foredeck of the lyman 3/8 mahogany over marine ply. I'm considering getting glen-L plans for a 33 lobster boat and building my next boat from scratch. I'm far from an expert and wonder has anyone done a glen-l designed boat (any coments)and any and all thoughts on cold molded hull vs traditional carvel planked for a glen-L lobsterboat. I invision a 15 knot weekend off shore fishing boat with the boys as well as a harbour hopper in long island sound with the mrs.

    Just looking at the glen l site it seems to spec conventional strip planking or strip planking with a triple diagonal veneer cant see a plank on frame option but it could be scantled just not listed. In general a composite strip plank or strip plank with cold molded exterior would give a lower maintenance style of boat than an equivalent carvel build.

    On the whole cold molding will also give a more homogenous monocoque structure than an equivalent carvel build. I'd sound a note of caution if you cold mold it takes quite a long time and it is quite tedious each veneer has to be spiled to fit it's neighbouring veneer sometimes a little sometimes a lot. The gougeon brothers on boat construction is a good reference for the method and you can now download it for free from the west system website.

    I'll second the comparison of the two methods. A molded hull and a stripped build will both be tight and dry, while the carvel will need a continuous maintenance routine just to keep it tight. The carvel will probably be a faster build and heavier, but is also something easily repaired. Both molded and strip hulls are more tedious to build, though easy enough to get your head around. They will be harder to repair, but insurance companies love them in comparison to carvel. I don't know if they offer a carvel build option, but there are plenty of downeast designs that do if truly interested in this method.
