Greetings, fellow enthusiasts,
I am converting an Alberg 22/CapeDory22/Pearson Ensign to a short gaff rig, am open to suggestions, particularly on standing rigging and staying. Inspiration came from Michael Kasten's designs: high aspect ratio like a Baltimore pilot, short gaff like the Dutch.
Plan is to use the stock mast (25 or 26 feet long), in case any future owner regards my work as heresy. Gaff will only be about 3.5 feet long (carbon fiber tubing purchased already) with a single halyard on bridle. Throat of gaff would be maybe 2.5 feet down the mast to keep mainsail luff long.
I will stick to the working jib and forgo a genoa, in favour of greater area in the mainsail. Stock masthead main is only about 118 sq ft, mine would bump that up to 150 or 160. Obviously, the mast will have to move forward a bunch in order to maintain balance.
If I move the mast forward a foot, it will be in line with the chainplate that was used for the forward lowers. I will use this front chainplate for the uppers and do away with forward shrouds. Is this scary?
The middle chainplates would now be used for the aft lowers, at about the same angle as always.
This leaves the aft chainplates. I could run intermediate shrouds from them to a point between the spreaders and the masthead, seems prudent. Maybe someday (in phase 2), I will bring the jibstay about 3 feet down from the masthead, and have it meet the mast at these intermediates so they can help tension it. But I would still need running backstays (at least in anything but light air).
Since I am going to need running backstays anyway, I wish to launch (phase 1) with the jibstay remaining at the masthead. I realize this means I will need to make greater use of masthead running backstays to tension the forestay. But I have freed up my winches (no genoa sheets) so I may be OK on that front.
So my first question is this: If I have to use masthead running backstays all the time anyway, do I need to install the intermediate shrouds going to the aft chainplates? My initial reaction is yes, it would help prevent losing the stick in case I blow a tack and don't get my runners sorted out in time. I just wonder, though, if they are worth the extra weight and windage aloft. If these intermediate shrouds only have 2 feet of sweep aft the mast, would I be better off with highfield levers that anchored farther back, and would allow me to get rid of the running backstays?
I look forward to drawing on your impressive pool of expertise,
Vincent
