I've decided I need a spinnaker..."Kattu" may be sensational upwind, but not so much off the wind. The plans don't show any dimensions; I would like to know if any Tiki 38 owners have figured out an optimal size for luff and foot, assuming a symmetrical chute.
I use an asymmetrical spinnaker in a 'snuffer sock'. Works an absolute treat particularly in light weather and can be carried on a beam reach.
If you can get the sail maker down to your boat s/he will measure it up with little trouble. I extended my rig by a metre so my measurements would be wrong on a standard size rig. Otherwise a line drawing of the boat and sail plan may be adequate.
Mine is rigged with a continuous tack line running through turning blocks tied to each bows and cleated off on the mooring cleats on the mast case.
The turning blocks for the sheet/clew are opposite the leading edge of my pod so that I have a good lead to the jammers on the pod.
A snuffer sock makes the sail very easy to manage when hoisting and dropping as well as stowing in the sail locker.
our mast is only 10.5m high. we use a symetric spi and have a drifter too. great sails... you will need i one day. specially the drfter is very usefull for us. works till 80 degree upwind and is smaller then the spi of course... we use it in stronger wind liek a spi... too.
Thanks Dave and Hans for your input; I am hoping to find a decent used spinnaker. That's why I would like to know what the optimal dimensions are, so that I can look for one nearest to that. Finishing and launching this build ate into the cruising kitty some so now it's time to tighten those purse strings!
