There is no Cutwater specific sub-forum on TrawlerForum.com. Feel free to post anywhere. It is rare that a post is truly brand specific anyway. Engines are engines, electronics are electronics, sanitation systems are all the same as well.
All of the boat manufacturers design and build the hulls and decks and marry them. The rest of the systems (engines, electronics, cleats, lights, doors, hardware, stove/oven, fridge, microwave, toilet, sinks, faucets, pumps, hoses, lines, electrical, etc) are all manufactured by third party manufacturers and installed by the builder.
