AllThumbs So, just to be clear on this, looking at my sail on the living room floor right now, the bolt rope is definately shorter than the sail. If this should not be so, then my sail has stretched (doubt this since there is still 5" of boom on the boat with the sail hoisted fully), or the bolt rope has shrunk. The bolt rope is stiched into the sail on the top 5" and bottom 5". There is noticeable wrinkling of the sail near the bottom due to the short bolt rope. I am considering removing the stiching at the bottom, pulling the rope thru, and then restitching. I am also adding my own slugs using a kit from Marine Fabrics, Sailcloth, Sail Kits, Canvas and Sail Hardware for Do-It-Yourself (slugs and shackles) as per this web page: Adding Sail Slugs . I guess the real question is whether the bolt rope is supposed to be shorter that the luff of the sail.

blt2ski SVDS,

Talk to a local sail maker and see what they say re bolt rope vs slugs. Other than the reefing part, the hoisting/dropping that SD talks about would still make sense, even on a little boat like yours. Same with the loose foot to. In fact, it could even be more important in different wind conditions making the sail have better shape etc.

On the other hand, if you are able to sail it one design, the class rules will override any common sense, ie having slugs vs bolt rope if Bolt rope is the class standard.

sailingdog SVDS-

Didn't realize a butterfly was such a small boat... on larger boats, the points i mention are a bit more important.

SVDistantStar In the first picture, the blue line holding the boom up is my halyard for the sail. The hole that its tied to is the hole that the sail gets tied to.

SVDistantStar SD, your getting a little techy on my little 12' boat now. I don't have any sort of reefing system. The boom goes in a sleeve on the bottom of the sail. I do like the idea of loose footed on the sail since it would make stowing it alot easier. Right now ive got to remove all the rigging from the boom to remove the sail from it.

This picture shows the running rigging of the boat.

This shows the sail attached to the boom/mast.

sailingdog Main advantages of having slugs over a boltrope is that the sail is going to have less friction when being hoisted or lowered. You can also leave the slugs in the sail track when reefing the sail, which makes it easier to manage. Finally, get the sail with a loose foot, which makes it easier to control the shape of the sail, especially with the outhaul, since there's less friction against the boom. You can also get your reefing lines around the boom without having grommets or cringles put in the sail on a loose-footed sail.

SVDistantStar Ive been thinking of having a new main made for the Butterfly. Currently it has a bolt rope, im considering when i have the new sail made to have slugs installed. Any advantage with slugs over the bolt rope?

sailingdog An excellent idea. Get metal slugs if you can...they are more UV-resistant than the plastic ones...

AllThumbs Thanks for the advice. I will get the sail checked out this winter.
