| You're saying a Cabo Rico 38 is faster than an Express 30?

Doug, I know you to be a man of numbers and stats... so I will provide the
table below from SailCalc... along with the fact that the Cabo Rico 38 is
the fastest cruiser I have sailed on. We averaged 11 knots over Yellow Banks
in the Bahamas on one.


Well, that's not slow... OTOH what were the conditions, and what will
the boat do under "normal" (meaning normal for the area and season)
sailing conditions?


Performance Comparison
Hull Speed Cabo Rico 38 7.33

Express 30 6.63


Well, that's to be expected when the CR 38 is more than 1/4 again as
long... assuming that the boat will reach close to hull speed under
normal sailing conditions.


Sail Area to Displacement Cabo Rico 38 20.05

Express 30 18.57


Now that's an interesting figure... the CR 38 has pretty decent sail area


Displacement to LWL Cabo Rico 38 359

Express 30 249


It's also got a much heavier "footprint." I'd be surprised if the CR 38
got all that close to hull speed except under favorable conditions,
whereas the Express 30 performs quite well under a wide variety of
conditions.

I think that off the wind, especially in choppy seas, the CR 38 would be
faster... on a long passage it should be faster...




Yes... faster than the Express 30.


As I said under some conditions, it would be reasonable to expect that.

But for all-round sailing? Let me put it this way... PHRF rating
committees think that the CR 38 is noticably slower than the Express
30... enough so that they would rarely be in the same class.

BTW the Cabo Rico 38 is a Mark Ellis design, right? He's noted for being
able to design comfy boats that sail well... but he's not a magician!
