Pierre,

Understand that increasing static stability does not enhance ride, never rejected that. That is why long length is needed so that static stability can be reduced, and have to go back again to mentioning that long length is not considered often with modern boat design.

When the modern 35' fat hulled design is compared at bottom waterplane, more pounding will be likely to result. They are not completely flat but deadrise is not that great either as some of the broad sterned euroboats show. With modern BWL say 10'-8" compared to jubilee 8'-4" BWL that has to account for more uncomfortable ride especially when overall length of 50'-0" compared to 35'-0" is considered.

Hate to keep beating this around, but long length and narrow beam is proven to offer a better ride.

Apex,

You came back again not to offer anything useful, only to detract. Dont mind having you onboard, it would be good to stay on topic in regards to the design at hand and make some helpful suggestions to work out a better design. If not its better to just excuse yourself from this discussion.

Peace to all.

I dont get the draft . In you opening post you say 5' max . Then you say hull draft of 1'4' and then 19".

You need to get a better idea of what you want, i think.

Sam, are mast hoops required or can just line be used.
I believe I saw someone post that pic a while ago stating it was on lake Eire. I am not 100%. If so I think you are screwed.

Greetings,

Frank & Ward, the AS39 is a brilliant work, the design parameters set by the Wises were successfully accomplished. It is a great proven liveaboard with periodic ocean passages safely made.

The high freeboard with high COG is not as seaworthy as the jubilee and if knocked down to 90 degrees would be more prone to stay on its side (Bolger took that into consideration and put in enough ballast to allow fast recovery),
if inverted to the 180 degree position because of high freeboard the AS39 would recover quickly but you have to remember again that a longer boats such as jubilee are more unstable upside down, if you look at the plan view for boat boats that will be obvious.

The gaff mast would be an ideal setup. Since boat boats have similar hull shape other than freeboard, it would be quick to measure water plane and size sails accordingly, but in order to keep costs low, good used marconi sails are more available and for that reason would be used instead.
The heavy gaff rig on AS39 almost becomes a cat rig because it so far forward, with jubilee the rig is more aft and has more bouyancy forward.
Going with the marconi rather than gaff is the real dilemma of this design.

Interior arrangements such as double working desks and small head area are not needed. Exterior engine exposed to swamping, the hole for the tabernacle, very high cockpit would be negatives for seaworthiness.

Pierre,

Eventhough your posting are critical they are appreciated because they are condusive to rightly thinking this design through. Trying to make questions more understandable.

Frank,

Believe that all posts in regards to draft have always been 13"-16" depending on displacement. Jubilee could have been designed with a box keel which would have made draft deeper, that would make an easier design to work out, but the shoal draft qualities would be gone, so deeper drafts were taken out of the design.
