The snow is melting and the ice too (Great Lakes froze over completely again this year!) so I am thinking about sailing again. This has probably been asked before but the clew attachment points, how do they work?? Top one would tend to harden leech leaving a loose foot, bottom one would harden foot but perhaps tend to open up leech, right???? So you can't get both so the compromise is the middle ???

Depends on the cut of the sail

Yes of course you are right did not cross my mind at the time of writing.

The one I have has an expanded roach requiring horizontal battens.

The so called "lapper" designed by the late Hans Fogh in Toronto.

On my self-tacker I place the clew higher for lighter conditions for a fuller sail shape and lower on the clew board for windier conditions.

Mike, your comments on trim are correct. If the top part of the jib is trimmed in to much compared to the bottom, then move the sheet attachment down on the clue. This will ease the top and harden the bottom.

On the original 400 jib I've found that attaching the sheet to the second hole from the top gives the best trim when close hauled.

Mike, when do you use the "lapper"?

The lapper I have is a race sail (Pentex cloth) so I only use it when the wind is above 15 Knots true to about 25 then between 25 and 30 it is used with a reefed main. Above 30 I use stock ST. If memory serves the lapper is about 225 sq feet.

In this high wind I cannot easily get it flat to go close hauled and I obviously am not going to mess around with clew attachment in this wind. Also the purchase on the coach house roof does not permit getting the sheet all the way in unless I luff up briefly so the sheet goes slack which permits me to grind it in; I then steer down. This may be partially due to low stretch line I use which seems to provide a lot of friction in the (tortured) path the sheet must use.

But overall it is a very nice sail IMHO

Mike, what do you use below 15K? Soon after I began sailing my 370 in 2006 I realized that the original self tacker was not enough sail in the light winds that we experience on Lake Michigan. At that time I was exclusively a cruiser so I added a high end dacron 135. It's still my "go to" cruising sail. AS I began racing I needed some more power below 10K of wind so added a 155, which we now use up to 15K, and then go to the 135 above 15K.

I have high end 155 for 5-15 and a code 0 for very light wind . For distance races on Lake Huron the Code 0 is really fantastic. Last year in about 5 knots of wind and AWA about 50 I was seeing 6 knots of boat speed. We cruise with stock ST but I would like a 135 dacron but with a kid in university and another who ski races something has got to give and its dad's sail inventory!

Mike, tell me about your Code 0. Sailmaker? On furler? Flown from sprit? Sprit reinforced?
Thanks,

It was made by Doyle I have it on a beefy Selden Sprit about 30 cm (12 inches) out from bow, no furler, AirX cloth (0.7 oz??), about 850 sq feet, has vectran luff line sewn in as well. This iis mportant in order to get the luff tight for good sail shape.

Mike, Do you douse it just like an asym?

If we do not want to tack we run out the genoa then ease the hallard and run the clew to v berth hatch and douse into v berth. If you want to tack we roll out genoa then tack and let the code 0 blow on the deck ease hallard and douse into v berth.

While you ask for raising we have low back stay tension raise tighten hallard and then haul back on aft stay to get luff as tight as possible.

Thanks Mike. Another question: under PHRF can you carry both an asym and a Code 0 without penalty?

Under LH PHRF and elsewhere I believe that a Code 0 counts as a spinnaker. There is no limit to the amount of spinnakers you can carry. On Mac in cruising class you can only carry two spinnakers. So I have one asym and code 0 on this race.

This was an issue for us last year when we tore our spinnaker and dropped from around 2nd,3rd to 9th on Sunday night. We made up one spot when we could reach with our 155 genoa Monday morning.

Oh well maybe this year we will do better.

With regard to ST on 371 can anyone assist with loads on blocks/ block on track, I have 2:1 at the moment? Any advice as to what brand/size blocks I should be using?

Thanks
