Any one have a diagram or pictures of the masthead setup for a drifter halyard? What size rope? What size block? Does it run inside or outside the mast? Thanks

Frog... that would depend on which furler you have?

The furler on Penny II is a snapfurl. The boat jib halyard is used on the sail from what I can tell. Any help will be greatly appreciated.

I'm winging it a little with my advice about the snapfuler as I think it requires a method to lead the halyard back away from the furler to the mast. This is typically a block or fairlead of some sort down a short distance from the mast truck.

The drifter that has been produced by Ulman sails is a full dimension luff which it seems to me would have a problem dealing with the jib harlyard. I've raised this issue before and never got an answer on it so its likely not a problem or is dealt with in some way.

I would suggest discussing this with who ever makes your drifter. I see a couple of possibilities. If the sail has a full luff, it could be tacked like an asymmetrical ahead of the stay and handled by a spinnaker halyard mounted on a masthead crane (a forward extending attachment to the mast truck) in order to get the halyard forward enough to clear the furler.

The second method would use a drifter with a slightly shorter luff and require that the turning block that is used to turn the jib halyard aft to the mast be a double sheaved block to also accept the drifter halyard.

Have I made sense?

As far as the halyard size, quarter inch would work for a drifter halyard, the blocks would not need to be very heavy.

I understand some of it, but the rest is mush to me. I have a diagram of the masthead, but cannot figure out how to get it on a thread. I will EM to you and you can see the snapfurl setup.

Frog, I have cdi-ff4 and when I use the drifter, I simply use the spinniker halyard, which is an internal halyard.
