OK, in our new boat search we are starting to get pretty serious about the Mainship 390 and the 400. We want a minimum cruise speed of 15 knots (we will often cruise at displacement speeds, but we want to be able to COMFORTABLY run that speed). We are only interested in twin engine models.
It is my impression that the 390 is pretty much the same hull as the 350 except with a more substantial swim platform glassed/bolted to the transom. I assume they did this to try to reduce the squat. I'm pretty sure that the 350 hull was designed to run at 7 to 8 knots, and the only way to get more from it is to pour on the HP, resulting in a pretty inefficient boat at higher speeds. Am I correct in these assumptions?
Is this also the case with the 400? Since this design started about 2002, did Mainship design it from the get go anticipating higher cruise speeds?
Thanks in advance.
