Not around here, nor billfishing. Thanks for the contribution.

Cheers.

Guillermo,

There were some excellent designs built in the US from the 1930's through the 1950's, cruisers and sport fishermen. Many had the performance you mentioned, trolling for hours at 5-7 knots, and able to get home at 15 -17 knots if needed. The ones in my personal experience usually had a narrow beam, deep vee entry transitioning to a nearly flat bottom aft, with rounded chines and a skeg. Very good sea keeping, able to maintain planing speeds in seas over 3 m without pounding (more than once, my passengers would fall asleep while we were travelling in steep swells at 15 knots). A deep keel and skeg helped tracking in following and quartering seas. Perfect? No, very tender; rolling at anchor in even moderate chop, and very wet while slicing through those steep swells. The lines of those classics might make a good beginning for a modern iteration of the offshore power cruiser/fisherman.

Here is the 19m N Irens : http://www.tuco.dk/default.asp?mn1=5...&mn3=63&sid=80

Perhaps a bit above your length. An I do not exactly understand how it is built. I fact, I do not understand how at all ...


It is difficult to find styling for a rather fast and low power boat by looking fishing boats. Fisherman are more on the heavy slow boats, except recent (say 1960 and newer ...) outboard powered hulls. Olders boats were built carved wood. This material does not lead to designs compatible with your goals.
Older typical french brittany fishing boats were displacing from 35 to 70 tons for length 15m 18m. Even open boats around 9m-10m were in the 8-10 tons range, and I fear most other countries fishermen had the same weight constraints from building methods and bilge size.

Thanks a lot, fcfc and Charlie.

I think the long thin designs of the 20-30's are great. The extra deck area of a modern sport fish bow might be an improvement while handeling the ground takle , if it could look good.

With a bit more flair at the deck?
