371 jib dimensions

Blair,

Not sure of the working jib dimensions, however, I race my 371 in Canada and my assigned PHRF # is 102 (with chute and 145% genoa). To modify that number for a working jib you add 6 sec per mile giving you a PHRF of 108. If you will be racing without the chute (white sails) you can add an additional 18 secs per mile and your PHRF would be 126.

The 371 has an IMS # - see the thread titled IMS ratings under Manuals & Drawings on this site. Some people use a rough formula to convert  IMS to PHRF which is (PRHF = -480 + .9*IMS).

Hi Blair,

I live in Winnipeg but Blondie is moored on Lake of the Woods. Last year I bought a UK 145% genoa from the UK loft in Vancouver. They should have that sail's dimensions and you can get an idea of how much it needs to be cut down (if at all). Also, the North loft in Vancouver will have the Hanse 371 genoa dimensions in their database.

I have 6 winches (four in the cockpit, 2 on the coachhouse). It makes it very easy to fly the chute. You can get by with 4 (2 cockpit, 2 coachhouse) by taking the spinn sheet to a coachhouse winch and leaving the guy on a cockpit winch but occasionally you may have contention for a winch when you are rounding a mark and need to have the genoa pre-loaded. Other useful things I have added are a side ways mounted Spinlick rope clutch (same version as the ones supplied with the boat with the added sidways mount kit) on the mast just under the spinn halyard exit point to run the spinn halyard through. That way you can jump the halyard at the mast and if someones sheets in too soon and the sail fills, you won't burn your hands before you can cleat it. The rope clutch allows you to launch the but the line won't reverse. Then when you dump the chute your foredeck person will open the rope clutch just prior to hauling the chute down. I added one folding mast step on that side of the mast about 18 inches off the deck so its easy to step up and open the clutch. This step is also useful for tidying the main or putting on the headboard shackle.

I also have mounted a large cam cleat on the other side of the mast under the main sail halyard exit point. It is extremely easy (and fast) to raise the main this way by jumping it's halyard at the mast. You can jump it up to about 98% of the complete hoist then do the last bit with a winch on the coachroof. Also, the cam cleat lets you park the halyard as you drop the main and lets you drop it, fold it, drop more, etc.

I use two large Harken racheting blocks on the toe rail near the back of the boat which the sheet and guy are run to. You can also use a snatch block for this but the ratcheting capability means tha in light air you don't need to put the spinn sheet on a winch since the faceted cheeks and the ratcheting give the block good holding power. Also, for the spinnaker I have set up "twing" blocks that ride on the sheet and guy and are used to "twing" or bring the sheet and/or guy down to a point on the toerail approximately near the shroud bases. Twinging lets you control the chute better (make it deeper or more stable for certain conditions).

I will be taking pictures of this stuff and will put them on this site next week.
