Perhaps the Mainship people are missing the fact that not all Mainship questions make it into the Mainship sub-forum. If it's an engine specific question, it goes in the engine section. If it's an anchor question, it goes in the anchor forum, and so on. Don't just assume that a lightly used forum that is Mainship specific means there isn't a lot of activity by Mainship owners. It might likely be just because it is a little diluted by topic-specific questions.
And Craig is right... Those guys have said before that they are all coming and they never really have in any great number. I, for one, would love to have them all here. I tend to get a little sick to my stomach when I try and use the Yahoo Groups. Might as well be an alt.trawlers.mainship BBS newsgroup
