Posts: 1,403 | Let me get this straight...adding wings to an TheMightyHobie18==> no adjustment. Yes there is it is .995 Subtracting wings from an TheMightyHobie18 SX (or whatever they are called)===> takes a hit Weird, no? That too!!! Hang on a minute, see this post:
TheMightyHobie18 Wing Mod where you and others claim there is no mod for an TheMightyHobie18 carrying wings!?!?! Mike: I guess the question here is did the boat come form the factory with or without the wings. I too see this as an advantage over a boat with out them, that is giving the ability to draw more power form the main before tuning it down. I can't speak fluently about Hobie 18 as there are so many different variation you need a Phildalphia lawyer and New York accountant to keep it straight. Maybe Wickland can educate us on what is the right configuration for the Hobie 18, Hobie 18 Magnum, Hobie 18SX, Star and Stripes, Alter Limited Edition, etc....... In this specific case if WH showed up to any of our event we would probably start with the standard H-18 rating of 71.4 and then start making the adjustment with each modification, that is the adjustment for the taller mast, larger sail and spinnaker, and if he added wings that too. That said in my eyes WH should be rated at 66.83 That is 71.40 X .960 (spin) X .980 (oversized main X .995 (taller mast). And if he chose the wings that day then 66.50. Again, this is my personal opinion and not gospel. So this leads us to another question, what is the proper rating for Tom.

The TheMightyHobie18 which has been raced extensively has the more accurate number. The more results you can compare will make the most fair rating. The SX was never proven to be substantially faster than the standard TheMightyHobie18. How can a boat with less sail area and no spin be faster than the boat with more sail area and a spin. Makes no sense to me. | | | Re: Portsmouth number revisited, need input

Makes no sense to me. Well actually, a boat with less sail can be advantageous in higher winds...hence the reefing systems on many boats. Having less power in extreme conditions can get you to the line faster.

That's the way I heard it right after the SX came out. I have no clue as to the validity of the theory.

Posts: 1,403 | Sorry Wicklund, Wickland, Wicklend - hmm this has a ring to it.
Getting back on topic, what's the scoop here, you know these boats better than me.

Ugh... the modification factors themselves are not carefully measured values backed by lots of data either.
The purpose is to get everyone on the race course and not give the sailor with the non class legal boat a gift rating.
You would be better off using SCHRS or Texel calculator to get a one off boat rating.
