Hello - I've been contacted by our new member in South Africa. Posting it on his behalf and hope someone can help.
I had in my mind kind of given up on a junk rig for the little dingy and had resigned myself to using a boomless lug sail for which there is a design available. Much in the line of the rig that is used by Roger Barnes of the UK Dingy Sailing Association. Nice and simple and probably the best place to start. However as an engineer, I am fascinated by the junk rig and I had already also decided that I would build the tabernacle and install the chainplates for the Bermudan rig which the Argie 15 was designed in case there was a requirement to go that route in the future.
I am looking for some help with the design of a suitable junk rig so if you could point me in the direction of design calculations or somebody who could assist me that would be awesome. I think that I understand that the centre of effort of the sail should be where the original design was so with the help of the original rig and the lug rig – I should have a good idea where to go. Because the area where it would normally sail generally has light airs, I wanted to have the option of a really oversized rig that could be reefed down as required?
