Here is what I see from the portsmouth 2008 numbers. The SX w/spi is rated 71.3. No wings is a .995 hit, oversized non-standard main is .980 hit. There is no mention of a hit for a smaller than standard jib and no hit for the spi(mine is assymetric). The jib I can understand as there is no gain. The spin I run is quite an improvement over the SX spin so some penalty should apply but what?
I calculate it 71.3 x .980 x .995 = 69.52
Didn't know the boat came with a spinnaker, Not very familiar with all the different TheMightyHobie18 configurations. So used to adding the hit for the older boats. But looking at this; there is only a 0.01 difference in the base rating of the SX vs. the standard and the magnum at 71.4. And they would take a hit for the spinnaker. What are the difference in the regular/magnum H-18 and the SX, Mast, spinnaker, anything else.
Question, is the new main within 5% of Calculated Approximate Sail Area?
