Re: Retractable Bowsprit DIY
I'm curious, what sort of sail are you referring to, precisely? A Code 0? ...
The sail I have in mind is often referred to as an A1 as in Asymmetric Racing Spinnakers | Doyle Sailmakers
. Not having done the math, Ii would think an A1 on a CAt27 with a four four sprit would have 70% or more area than a cruising chute. combined with the convenience of a furler, this area makes the sail more useful in the light to mid winds. In higher winds, the price of sailing with a genoa is not so bad...
I agree your cruising chute is providing excellent drive in your photo, and a larger A1 would be dicey, but winds in the high teens to low 20s is not the sweet spot where most sailors are looking for more go anyway.
Certified...in several regards...
