Definitely one of the factors that should be considered, along with capacity, maneuverability, comfort, increased loads and costs from a longer hull, etc. I have not done such an evaluation and afaik, nor has anyone else.
Hi
looking back at the files posted by Rick/Rob for the optimized LW hull for the Solitarry I see that there is about a 10-20% difference in the 5-15knots range for drag for differently optimized hull types (but same length).
Did anybody by chance calculate the difference in drag for the WW vs the LW hull? and the resulting momentum.
Given that 99% of all sailing will be done with the WW hull in the water I was wondering if this should be a factor in considering WW hull length (or even general WW hull design)?
