#1 size

[LarryE-old]

Is the class legal #1 a 155% or does it figure out to be 153%?

[LarryE-old]

Question for sailmaker. Looking to purchase a new jib, in the futher. My PHRF handicaper says the class jib works out to be 153%. Can someone verify this or is it the same as a PHRF 155.
Thanks.

It is less then 155%

This issue is kind of confusing. The max LP allowed for a class Genoa with a tuff luff or other foil is shy. By my calculations, the max LP allowed for a hanked on sail is right at 155%. I'll go for hanks every time, thank you very much! I'm sure that the supposed reason for this is the extra "sail area" of the foil but IMHO they aren't worth the trouble or the money for closed course racing.

You need to check the max. sail area codes for your particular PHRF region very carefully as they will vary from one PHRF region to the next. In our particular PHRF region the max. allowed genoa size is in fact larger than the max. class legal genoa size., however that is just in our particular area and it is by no means a massive difference.

[dave]

What is the max Genoa size in your area? The PHRF standard without penalty is 155%. Just curious.

The J on the 7.9 = 9.5'. The class rules state that the max LP for a hank on Genoa is 14.725'. 9.5' x 155% = 14.725' on my calculator.

Base handicap for Lake Michigan PHRF uses a "Jib overlap (LP) of 155% of J."

[dave]

Larry E, the rules say that 14.66' is the max LP for a class Genoa with a luff tape [tuff luff, etc]. 14.66 divided by the J [9.5'] = 1.543 or 154.3%. Not worth crying over either way.

OK, the tuff luff type genoa max LP = 14.66 ft, but is there a place to find the max hoist dimension on the genoa luff? Also; what is the maximum length of the headstay? I looked through the class rules but could not find a direct answer to either of these questions.

Check out 2.5.B & 2.5.G for the head sail. Max headstay length is 31'8" A1.C.9

Max hoist is determined by what your sailmaker thinks will fit between the jib halyard sheave and the tack attachment point with proper space for stretch and/or adjustment.

Thanks for the tips! I also spoke with Spike yesterday and they make theirs with a 30 ft 5 in luff to allow for halyard hardware, stretch and clearance to tack. While we're on this subject,does anyone have the leach and foot dimensions for a 155 (tuff luff headstay) ? It's never too early to get ready for spring sailing>

Why didn't you ask Spike when you had him? It depends on the clew location. Just because it's a 155% [or a tad less] doesn't mean that the clew hight is the same for every sail. The foot and leech dimensions change as the clew goes higher/lower.

[Marionete]

Spike had to take another call, so we ran out of time. One other question as far as new genoa's are concerned: what is the consensus on having a 3DL type (one piece, no panels) vs a tri-radial design with panels? I am interested in hearing opinions on life expectancy (# of seasons) and stretch characteristics for each.

It would seem that a panel-assembled sail might have some additional strengths due to the seam overlaps - given the same thread properties of kevlar, etc.
