[MHml] Cat vs. Tri

[TLam45387 at aol.com]

Rob,

Two questions on the Cat vs. Tri discussion.

1. If we look at "Team Phillips" as two boats sailing side-by-side, each 
would perform as a single hulled racer without the weight or drag of any "extra" 
hull(s).    The only "extra" is the connectives and this would be common to all 
four types.   Therefore would not the biplane cat be the fastest by your 
arguments. 

2. Looking at Jessie's proposal on a sail area or rig specification race, how 
would this affect a proa having to use a J24 rig and tack it on a short 
upwind course?
