Utahsailor, so it was you who designed the
Hood Sea Furl. I had one for some years and overcame halyard wrap by attaching the
spinnaker pole topping
lift to the
jib halyard attachment point on the non-rotating part of the top swivel. Hoist the sail and the topping
lift goes up with the jib halyard then put just a little tension on the topping lift which pulls in and down on the tensioned halyard and it can never wrap around the foil. The halyard pulls up and the topping lift pulls down.
That can be done on any
furler when there is an available
spinnaker pole topping lift or similar lower halyard. Doing that the topping lift goes up from its own turning block but as there is not much tension it simply bears on the top of the sheeve box which is smooth.
When I change to a 3/4 size jib on my now ReefRite furler there are several feet of halyard between the top swivel and the jib halyard block in the
mast. I do the same proceedure and the halyard never wraps. In fact I often do that as a precaution even with a full length
head sail. I also have a saddle on the
mast that deflects the halyard away from the swivel and the foil.
Eventually after several years the Hood Seafurl would jam. The wire forestay had cut a short groove into the top of the Hood Foil. I
sold the Hood to someone with a smaller
boat and I believe now slightly shortened it's still working.
I don't have a
Lagoon unfortunately I only get to walk past some going to my boat, but that idea might be helpful.
