They are a pretty good float on the water, and not too heavy. But a bear to put together. The parts were molded by Lanier on the same line as their "classic" ARFs and the left side almost never matches the right side. Put them together dry and then start tacking with thin CA at the center, working out to both ends. Watch for twists as you go. Once they are tacked together and straight, go over all joints with medium CA.

I put a light ply former down the middle of mine to keep the bottom from pushing in.
