I am racing my 1978 e32 and I get a 9 second handicap for a 135 headsail. This past weekend, in light air, in a 16 mile race from Ft. Lauderdale to Miami, we got killed. I'd like to go to a 155 or even larger. I'm thinking about asking a local loft to construct a headsail for roller furling without a sun cover and then a separate sun cover that can be hoisted with the spinnaker halyard.

Has anybody flown and/or roller-furled a 155 or larger headsail on an e32?

I humbly solicit comments and suggestions.

Most handicaps will allow you to go up to a 155% but once you go over that they penalize you. If you get it cut for roller furlng you should get a credit, especially for an above deck roller furler. I'm not sure what kind of racing your doing but if it's windward/leeward it's going to be tough because of the shoal keel. In the Beer Cans here in Chicago our rating was about 260 and we rarely won unless the winds were about 12knots. Less than that and the boat just doesn't go. We also had VC17 on the bottom and Dacron sails. You'd do much better in port-to-port races where the boat will most likely reach and thus perform much better relatively speaking, against the other boats in the fleet. In that case you'll wand an asymetrical spinnaker tacked to the bow.

You can look into a roller furled or non-roller furled Kevlar 155% genny from North and not be penalized---they don't penalize fabric type. If you go roller furled, you can get a UV sock to slip over it to protect it and forgo the UV cover on the sail. The Kevlar sail will weigh about 1/3 that of the Dacron and hold it's shape much better but it does cost more. Reducing weight above will also help the boat stand up a bit more. I'm not sure what your normal or average wind is like but in Chicago an AP Medium is good. Mine is a Light/Medium and is rated to about 12knts TRUE.

I'd suggest the Kevlar 155% and an asymetrical spinnaker for the race you described.

Paul,

Could I get a copy of your PHRF certificate. We are having a PHRF meeting tomorrow night and I'd love to see how they arrived at 260. I have already found that some in our fleet are getting 6 seconds for roller furling ( and I am not) and some are getting time for "cruising equipment" and I am not, though I listed my built-in diesel generator and air conditioning system on my application.

Much gratitude,

Russell

I'll see what I can do. We never had a PHRF certificate because we only raced in our club's Beer Can Races on Wednesday night and they developed their own rating just for that. I think the E32 "BASE" PHRF is about 190 or so depending on the region and other factors such as centerboard and tall vs short mast. How our club arrived at 260 I don't recall but we raced JAM (jib and main only) with roller furling, a 155% genoa, and a fixed 2-blade prop. Here's a list of Endeavour PHRF ratings I've found:

http://endeavourowners.com/dscsn/info/phrf.html

Although it doesn't add up, here's my best guess on how it may have been figured. If we assume LMPHRF gave us a rating of 204 and then factored in: 1) JAM (non-spin) racing (+25s/m credit), 2) roller furling 155% headsail (+12 credit), 2-blade fixed prop (+6s/m credit), that would yield a rating in the neighborhood of 247. They may have used a higher base or something.

(usually you get +3 s/m credit for a 2-blade fixed prop [West Florida gives +6] and +6s/m for a 3-blade [West Florida give +12]; +6s/m for a 135% head sail; +9s/m for roller furling, +25-30s/m for non-spin)

If we had raced in the SPIN section they probably would have used the LMPHRF rating of 204. New England PHRF (189-190) tends to give faster ratings to boats compared to the other regions. Chicago is considered light air so LMPHRF would probably slow it down a bit, say 204, giving it a slower rating. At least that would be my guess.
