Hello Clegg. Thanks for your kind words! I'm sure that you will have already seen the website, but for the benefit of others who may be interested, the pictures of the gaff rigged J with twin headsails are now posted, more detail to follow.
The gaff rigger carries a bit more sail area but the centre of effort is lower than the Bermuda rig allowing for a better scale look and predictable sailing manners. The centre of effort is on the same vertical line as the B rig of the Nottingham J so the mast position is the same and the Bermuda rig, and the gaff rig can be carried on the same hull provided that the sheeting is thought through at the build stage.
I've only just fitted the new, professionally made sails, but with my home made sails (looking a bit like Nora Batties tights!) the boat sailed very well indeed.
Peter Wiles at PJ Sails now has the templates for this rig.
