Lets not forget here guys that we are talking about a Hobie 16.

With this in mind you have to consider the following.

1. The hobie 16 main is far more efficient if you can get the leach as close to vertical as possible.

2. The rudders are far more efficient at producing lift than the hulls (no boards remember).

So while many of the opinions stated are correct for better designed more modern boats. It also remains true that to maximise performance from the 16 you need to move the CE aft as far as possible and then play with the rudders to suit. If you go to the nearest club where 16s are racing and ask around someone will be able to lend you a template.
