Try this; it's a pretty active group.

mainship : This list is for Mainship Owners and others who want to own a Mainship.
I cannot speak for twins, my 2003 390 has a single 370 Yanmar. Normal cruise is 7-10 kts. On a good day I can probably do 14-15 kts at wot. I only did that once to see what wot was. As stated the 350 and 390 are the same boat with some minor interior differences. I'm told that hull #1 did not have the large swim platform and handling was poor. The "bustle" fixed that. The 400 has about 8 more inches of headroom in the engine compartment, the salon is about 2-1/2' longer and the hull is longer because they did not include the bolt on swim platform in the loa number.
If you want to run 15 kts I don't think the 390 is for you. there is a lot of 400 guys on the yahoo group. You should be able to get some good info there.
