So what's the difference if it's people weight or stores? Best I can tell the boat should sail muc better with the weight down in the hulls as opposed to up on deck/tramps whatever
You are talking two different weights.
900 in just people vs. 900 + 1500 stores
For a given wind
speed each boat will sail best at a given weight. Competitive race
boats will select crew based on prevailing winds for the regatta
. Heavier winds = heavier crew. One design boats always specify minimum and maximum crew weights + max and min total weight. Most regattas won't allow changing crew on a daily basis but it is not unheard of.
If you are loading the boat to 1500 lbs it makes little difference whether it is crew or ballast. However, generally you can move the crew easier for the point of sail so crew weight is better than boat weight.
It make a big difference on any boat loading it with 900 vs. 2400.
