Mainship Yahoo Chat Group
This is an old and very useful "chat group" for Mainship owners. Some folks get a little frustrated with it as its an older platform with some what limited functionality. But, at the end of the day its all about the group, and the information they share.
There is no better place to get information on Mainships. Old Bilgewater uses the "email" selection and gets all the posts via email.
This is the main, "all boats Mainship" group;

Mainship "Vintage" Yahoo Chat Group
This is one was started by some folks for just "older" Mainships - pretty much the Type I, II's and III's
Its the same system as the "other" Mainship chat group, but the focus is on the older models.
