I've used marelon self jamming, I think it was 4". I mounted it so that it is not vertical but at an angle, the line comes down the mast to the lower end then up to the jamming end. Drilled and tapped for SS screws, I coated the screws with 4200 and hopefully that will minimize corrosion between the SS screws and the aluminum mast.
I think I'd be looking to work the line to the masthead crane by adding a block or fairlead or somesuch. That way, you can use the internal halyard and easily run it back to the cockpit.
Good idea to reduce the risk of corrosion Steve, I'll probably use my favorite compound, butyl, to do that. I'll also keep the screw penetration into the mast void to a minimum.
John, I thought about running the lines back to the cockpit, however, I really need to be up front to handle the sock and to attach/detach the sail tack from the 'tacker' (in my case it's a webbing strap that passes around the furled jib.)
Thanks. The WM 2012 catalog arrived today, browsed through all of it except the fishing and clothing chapters.
