135 genoa vs 155 genoa
 
I have a 1967 Santana 22. Considering a larger genoa, than the 135 I have, for light air races. Wondering if anyone has any experience with the amount of increased speed with a 155? Also the affect on vmg and ability to point and interference with the spreader?

I have a Santana 30 and I have a 155 and a 125. For light air, under 10, the 155 is much faster. Big difference. AT 15 knots the 125 is PERFECT. Has the boat moving about 7.5 knots. You will have to watch the 155 when tacking, I backwind it a bit just to help it move from one side to the other. The 125 ends right at the spreaders while the 155 is 5 feet back of the spreaders, almost to the cockpit. This is of course on a 30 foot boat, but it should be a similar experience on yours. If you sail alot in light air, the 155 will be great, if you sail alot above 10 knots the the 135 in my opinion is a better sail. Are you using a furler? Sail singlehanded? You mentioned races, check that the 155 is legal in your class.

I rarely fly mine. Pointing is a good 5-10 degrees worse, and it's actually worse in light air as it's a fairly heavy sail so it just hangs there.
If I had one in a lighter cloth (a drifter I guess) then it might be more useful, but my 155 is designed for stronger winds and a full crew to help keep her flat. I don't have that luxury.

The key as mentioned for lighter air, is cloth wt. A 135 out of 3ox nylon, ie spin cloth, would be better than the 135 your have I actually use this sail in winds under 5-6 knots, then switch to my 155 to the 15-18 range depending upon air temps, then go to a 140 I have for the 15-22 or so range, then down to a 110 and reefing after that.

If you can get a really light pentax, string style or heavy nylon sail, go for it, but if you get a heavier sail, then it will not be of any benefit at times.

If you are racing under PHRF, keep in mind that your rating is influenced by the size of your head sails. You may find that the increased rating (i.e. decreased time allowance) off-sets any advantage conferred by the larger sail which has limited advantage particularly in relatively short inshore races. The 135 is a more versatile sail and easier to deal with.

FWIW...

We have a LIGHT #1 or 155 and to be a true race weapon its has to be a VERY LIGHT material and it tops out at about 9 knots true wind speed

The light material makes it pretty fragile

In PHRFSoCal, it is assumed that you will be using the largest allowable headsail, which for you is a 155%. There is no benefit in going smaller unless (and this is important) the particular race you are entering, usually in a cruising class, allows a sec. per mi. addition for sails under 140%, which some do. It won't change your base rating however, which again, assumes your boat has the largest allowable sails.

FWIW every and any PHRF racer in this area declares and uses a 150% (except for boats racing OD or white sail cruising class) or they just wont be competitive. When the 150% is an appropriate sail for the conditions, it is worth far more than the 3 sec/mile rating hit.

This is a very light wind area in the summer and I have always regarded a 150 as the working jib. :D It's called the "number one" for good reason.

Racers around here have at least two 150's - a light & a heavy. The light one is for less than 10 knots, the heavy for up to 15-18 and then they start changing down.

People with furlers seem to settle on 135's generally.
