Milt wrote in part: ..... Chief designer Jeff Leishman can give you the technical side, but the truth is that stability is designed in from the keel up, and it's physically impossible for a vessel like this to turn over (that is, roll to port or starboard) and not recover.........> Wow, I have to believe that this is a misprint or misquote. Ether that or Jim/Milt haven't been to sea long enough to realize that there's a wave out there that will tear this kind of thinking to shreds. All small boats can roll over and do given enough time/exposure to the seas. Run a bad inlet on the wrong day and you can find this out. Be at sea in a big storm with confused breaking seas and you can find this out. Been there done that and have the mental images firmly burned in my mind. When the part labeled this side up is down and the bottom facing the sky you have get a better appreciation of the sea. Re stabilizers. The active fins seem to be brought up the most often of issues that turn these passages into more adventuress passages than any item. Milt mentions the two system that are available. I beg to differ with him as they may be only two that are available from Nordhavn there are other system that are available and work well, IMHO. Our stabilization tank was filled last August and hasn't been touched since. We have had nothing but positive results for it. It works 100% of the time whether underway or at anchor. It has performed well up to the 12-15' seas that we have been exposed to at this point. Does it have it limits? I'll bet it does but exactly where that might be I don't know. However we have 2 4" dump valves at each end to unload the 1500 lbs of water in a few seconds if required when we get pinned down on one side. Our righting moment is every bit as good as the Nordhavn from our stability tests and inclination tests that we were required to do before the tank was designed for us. Will Swan Song roll over??? You bet your a.. it would given the right sea!! Would it survive a roll? Most likely not as the glass, even at 3/8" and 1/2" isn't up to the pressure of a roll, IMO. We certainly aren't trying to take anything away from Milt and the Med Cruise. Good on ya all!! Crossing an ocean is tuff stuff in a small boat and isn't to be taken lightly. However, believing stuff like was in Milt's email can lead to having false expectations which can lead to not taking actions that might well need to be taken to deal with deteriorating conditions. As always YMMV..... Dave & Nancy Swan Song Roughwater 58 Caribbean Cruise '07
