Sail Upgrades vs. Prop Upgrade?
Richard - You're off to a good start with a fresh, clean bottom. This is proably the #1 most important thing one can do and at essentially "no cost" because the boat needs bottom paint anyway and then it's just a matter of timing, at the beginning of the racing season, and the details of puting it on so it's smooth. For example, with Petit Trinidad I use a thin foam roller instead of a knap roller and this helps. The second most important thing is a low-drag prop because the penalty in seconds per mile is not near as bad as what you gain. The cost of any new sail from a name-brand loft will probably be more than the prop. With regard to "new" sails, I'd recommend starting with the sails you have. Have a sailmaker give you an assessment of the shape - if there is too much draft and if they can be re-cut. Ask of the bolt-rope needs to be readjusted as they are nortorious for shrinking and will cause an increase in draft, especially for the age of your sails. If the sails can't be cost-effectively recut then these would be the first ones that should be replaced.Sail trim: I'd try this before adding new sails. Make sure the jib has telltails on the luff and put some tell tails on the ends of the batten pockets on the main. Next learn to trim the sail properly and see what happens. Adding telltails is a very, very, cheap solution for improving sail trim and, ergo, performance.After the above probably and asymetrical spinnaker may be in order but talk to some sailmakers first. I'm really not familiar with what would make this boat go better but on most boats the spinnaker is another item that tends to give a better time than the penalty for flying sails. Examine how the course is laid out and look at the apparent wind that is normally experienced. A full spinaker adds much more sail area, and therefore "horsepower", than an asymetrical but you need to have some good sail handlers to do it justice and from the postings I don't get the feeling you've got the crew hence the asymetrical recommendation. Again, I'd defer to a sail loft for their take but only if they ask what the typical wind conditions/angles and course lengths are.It's a wonderful feeling when you can eke 0.5 or 1.0 knots out of the same boat as before and racing will really help improve sail trim skills in this regard.Oh, and one more major item: currents. Make sure you know how the currents, eddys, etc. are on the race course - they can add or subtract big time. Maybe where you are the tides are so small it doesn't matter that much but up here with 12 and 16 ft tides it makes all the difference in the world.
