I noticed that in the revised mounting instructions, the mast is positioned 36"-48" forward of the backrest. This seems to be, at least partly, to put the lee board within easy reach but to still allow paddling. This also seems to assume that installation is in a solo kayak. With some tandem kayak designs, forward movement of the rear seat may be possible for solo use or solo use may be normally done by moving the forward seat back. How does one place the mast so that it is usable and able to be paddled in a tandem as well as solo configuration? Would one want two separate mounting positions for tandem and solo use? What are the performance effects of different forward/aft placements of the mast?

Thanks,
Jeff

Hi Jeff,
 Since I always want versatility I hear you. My answer was a fleet of kayaks. (Don't tell my wife this is why the garage is full of boats).
  As I see it each hull has strengths and limitations. To paddle while the cross tube is on the boat you need 48" from the back seat to use a double blade paddle or 36"+ if you use a bent shaft single  like the Krueger folk do.
 I mount all my tandems in the middle and add ballast of a passenger or gear to take care of weight distribution and don't try to move seating. Most folks choose this arrangement.
   Having said that: On a open cock pit tandem or like the Old Town Dirigio you can have a second mount area - maybe. To use the same struts and the same cross tube just cut everything and set up one position. Then if the hull shape is not radically different move to the next location, cut a hole for the new mast fitting and see what works. This can be tricky and the worst case scenario is ordering another cross tube assembly & fitting that exact location if the struts don't fall right with your first cross tube. You can always then move the rig back and forth.
 The sailing effects of rig placement are surprising few. Mid mounting tends to tack easier as the pivot is nearer the middle. Since the lee board follows the rig we find performance does not change to any great degree. Look at the Comet: 11' hull - mast way out front and it sails like a charm.
  We took it last year with PaddleFLorida.org  on a 110 mile trip from Key Largo to Key West called the " Keys Challenge". They offer guided multi day paddling trips and are great folks.We are signed up again this January.

   Or go Schoonering as David V likes to do! That way you have it all!

What factors generally determine whether you would go the schooner route? How is that different than opting for a larger single Batwing?

Hi Jeff,
 Schooners are mostly fun. You can take a longer double touring hull say 18-22' and get some amazing speed as the hulls could actually use more than 36-38 ft of sail. On David's longhaul double it may improve light air performance. Otherwise they don't have a lot to offer.Here is a schooner from Alberta -  looks like a blast:
 We have an easy rider 18'6" catamaran and the schooner rig makes sense for that also as there is enough length on the waterline and the extra sail area is necessary to move that much weight. Does this answer you question? If you had a particular boat I could give you my 2 cents on it as well.
