Dave,
Thank you. "How do they compare?"
Area:
Stock: 264 ft^2(1); Jib: 75 ft^2(2); Main 189 ft^2(3)+ (2)
Smyth's: 273.5 ft^2(4); Jib: 93.5 ft^2(5); Main: 180 ft^2(5)
These numbers come from a variety of sources:
(1) From Performance Catamarans website and Rick Bliss
(2) From Smyth's website
(3) By subtracting the stock jib area from the total stock area
(4) By adding Smyth jib and main area
(5) My measurements (Using avg. end area method)
Note: Smyth's site list the square top main as 189 ft^2 and the Jib as 97 ft^2. Another picture attached that show the differnce between the two mains. The stock is under the Smyth main.
Weight:
I haven't actually weighted them. However, if you pick up both sets of sails the Smyth's set, main and jib, feel like they weight just a little bit more than the stock main alone. Less weight aloft, I believe translates to greater forward speed.
Shape:
The Smyth's are much flatter through the bottom 3/4 of the sail. The first time we sailed with the stock sails, well actually it was the second time, I made the observation that the stock main looked like an old bath tub. Huge draft! The first time we sailed with the stock sails was our first time on the boat, it was in that transition period of the evening, between dark and damn its dark. We promptly capsized on our third tack.
Performance :
I beleive there is no comparison. That is just based on feeling at the moment. We tried to compare with another 6.0, both of us with stock 6.0 sails. We were trying to compare boat preperation and basic setup differences, not the differences in sails. However, it didn't work out that day. To many variables for the other boat, mainly, not his normal crew, causing head-in-boat syndrome.
Rating:
We take rating hits for the Square top main and the larger jib.
Controversy:
A little. It seems that whenever someone sees the Smyth name on 6.0 sails the immediate reaction is Express. Our boat is a 1996 and it a stock NA. We also don't use a spinnaker. We have laid the sails out for all to inspect and compare to the stock set.
Conclusion:
They are worth it! Worth the money and the rating hit.
