    The existing cruise ships are visually disturbing in ways I can't explain, it seems to be a case of continually upping the ante, I guess boredom can set in on those cruises without more novelties.

    Like others have said, you'll probably have a very hard time getting your stability approved through MSC. There are limits on passenger crowding heel angle, immersed freeboard, etc. Plus you'd need to provide a lines plan and your own analysis, preferably with a computer model.

    However, your local office can supervise a simplified stability test (SST) as you'd likely be classified as a monohull and you'd meet the other criteria. This is effectively a simple form of inclining experiment where you use actual weights of all gear and passengers. Your route (rivers, etc) would dictate the criteria that need to be met.

    I think that this trimaran was designed by the Builder Mike - and the Forum has not seen him since the 25th May, so I hope that he has not abandoned us totally.

    Mike, if you do read this, can you give us an update re your progress please?

    BlueBell Ahhhhh...

    Sounds like Builder Mike may be Jon's side-kick, helper, gofer, grinder, hand-holder, assistant, buddy, co-builder/designer.

    This is all I was able to find on Jon Coats.
    I hope he's a better boat builder than videographer!

    Sorry for my absence... Boat is progressing slowly... She fell off the blocks in the yard due to Hurricane that hit us last week of October, slid 5 feet and is fine, a few scratches. Got her blacked in sole completed, flybridge structure including roof done, Hope to install Outboards this spring and go for sea trail. will post new photos shortly
