Foresail Size Roller Furling

We are looking at building the home made PVC roller furler referenced here from the Com-Pac owners web site. We know we will need to have a different foresail. We don't really want to cut down the one we have and will be looking for a used one of appropriate size. The question is what is an appropriate size? Any one else added the roller furler and had to resize their foresail? What "size" did you need? We would like to have at least a 135 if not a 150, but know it needs to be "shorter". Any ideas??

furler

I purchased a schaefer snap furler for my H23 and had Torresen's install it. The forstay had to be shortened and a plate installed inside the anchor well to accommodate the drum. I had my original jib redone. New luff tape and sun shield was installed. (Jerry Mayfield at UK Sailmakers) There is no way I would put a 150 on that boat. A mild breeze would cause the boat to be extremely overpowered. I thought about a 135 but after reading several posts on this subject, I decided that probably wasn't a good idea either. The roller furler was the best money I spent on the boat. Happy sailing.

135 on an H23

I don't know what typical winds are like up in Muskegon but a genoa is very desirable in the light winds we get down here in the summer (usually less than 12 kt). I agree that a 150 is probably too much headsail for an H23. A 135 or 140 is better. Peter H23 "Raven"

Get an asymetric spinnaker

And keep your smaller headsail. Superior performance at all points of reaching. Can go 60 degrees off the true wind in light air. And the smaller headsail is ready to deploy for beating into the wind, or when the wind picks up. Big gennies are racing rule beaters that specialize in going to windward in light air. If you are racing, you surely need one. If not, the asymetric will give better, broader performance in light air. (We fly a 110 and an asymetric on our '77 h27.) David Lady Lillie

Foresail size/ What is standard forsail on H23?

I am a new H23 owner. Have just received my CDI FF2 and plan to install it using the foresail which came with my sailboat. What is the diference between a 125 jib and a 150 genoa? How are these "numbers" or "percentages" calculated? How can I determine what size sail I actually have? Thanks in advance. Alex H23 Santa Barbara

Standard foresail on H23 is the 110

This sail is also known as the working jib. It's a pretty good sail for most conditions except very light air. Trying to explain what the "110" means may be a bit more complicated, so bear with me. Most people would probably tell you that the number, e.g. a "110" jib, is the length of the foot of the sail divided by "J" the horizontal distance from the forestay to the front of the mast expressed as a percentage. For a "110" sail, this ratio would be 1.10 or 110%. A 135 or 150 genoa would be similarly defined. However, Tony Gibb (the author of "Advanced Sailing") states that the number is actually the "LP" of the sail ("luff perpendicular", or the perpendicular line drawn from the headstay to the clew of the sail) divided by "J". For a 135 genoa, this ratio would be 1.35 or 135%. Ultimately, a 150 is larger than a 135 which is larger than a 110 and I guess that's all that really matters. I hope this helps. Peter H23 "Raven"

Furling on a Budget

Thank you for your replies. The whole thing with the furler and an additional sail is to give us flexibility. We will be keeping our original sail in case we mess things up really good. This gives us our "Plan B". I just figured a large jib/genie will give up options. We can always pull some of the sail in, the reason for furling. We will need a "shorter" sail. We will loose between 12 and 18 inches in order to get the furler on the forestay and clear the deck/anchor locker flippers. We will be looking for a used sail and hopefully will find one with hanks that is close to the size we need and not need to cut it. This is experimental on a budget, the reason we are going with the home made PVC furler. Thanks again - Anyone else have a comment?? Bill Bowman H23 - Muskegon, MI

Furler Info?

I just aquired a 23' Hunter last fall and I'm curious about the cost of installing a jib furler and adjusting the sail size to accomodate the furler. I'm in the northwest and not very close to any large marine contactors who do this type work - Portland Or is probably the closest services. Any advice on the best system for the H-23 and who might be able to cut the sail and add the luff tape needed will be appreciated. Thanks, Lee

Compac Owners PVC Furler Site

I got this a while ago from this forum. The link is below. It just looks simple, doable and inexpensive. We would like to try it and see if we really use it. Later we can re-do it with a "real" furler. We are looking at getting a used sail that would be the appropriate size and using that, instead of cutting down our existing jib. That way, if it just doesn't work, we haven't wrecked our jib. Added the link at the bottom, but can't get it to work, so just cut and paste this: http://com-pacowners.com/tips/roller_furler.htm Bill Bowman H23 - Muskegon, MI
