| Here the sail is at rest and reaches to the bow. |
A great site on junk rig terminology can be found here:
'How does it work', but there is no substitute for looking at photo's and drawings of the real rigs. Each customized over generations for specific purposes. With my rig, here in Puget sound, I need a substantial amount of sail area for light airs, but the ability to drop all sails or reef quickly at the first sign of shifting to squal. This design was done partly with an old junk rig cad program 'SailCut8', running under 'wine' on a mac. But it's a bit too limited, so I printed and modified it to what looks right to my eyes. It may require a bit of a boomkin, but that's easy. It's about 218 square feet, which is not too different than the sq feet from the Alacrity's standard main combined with the genoa. If it's too much, I'll cut the bottom panel off, or if I need more, I'll add another panel at the bottom.

Jeff,
I'm following the Goblin with great interest and will trouble you with some questions along the way, if you would oblige.
How did you determine the location for the new mast step (which I am assuming is in the bilge)and is the forward angle for the mast a standard figure?
Best of fortune and thanks for any help you offer.
Regards,
Carroll Owens
Hi Carroll,
Interior space and limited choices played the biggest part in setting the location of the mast step.
The mast itself is off center by about 4 inches toward starboard and the 'head' bulkhead opening to the main cabin is off center toward the port, giving more room to get into the 'head'.
The original starboard cabinet is solid and the only piece of the original interior furniture, and the mast step is right in front of it. This allows for the mast to rake forward just slightly, maybe 5%, most people won't notice. I wanted more rake. But this will work well with the junk rig sail I'm making. The controls on the sail allow you to move the center of effort around to accomodate the mast.
So, the mast step is a very thick bit of tropical wood custom fit to the hull floor and locked into the 'head' bulkhead and the original starboard cabinet base. This is well ahead of the bilges. The seat for the mast is fastened to the mast step and is also butted right up to the starboard cabinet base and the 'head' bulkhead.
