Lcb lcf

[Don]

Experience has shown that for a directionally stable boat you want the LCF aft of the LCB, and you also want it to stay in about the same place as the boat heels (and the waterplane changes shape). This means wide transoms are a bad thing for directional stability.

Hi Earl(if you are there)
I’ve been re-reading this thread noticed this comment that the LCF should stay in about the same place. Would you like to take a stab at defining “about”, say in a percentage of the WL. I would like to know if I’m in the ballpark before I start stripping planks.

Thanks
Don

Under 1% is best; over 2% and you’re probably going to have an unbalanced hull.

Thanks Earl
I’m hovering around .5% so I should be OK.
