Pointing and Tracking
Stu's right about the drag from your prop having nothing or little to do with your pointing ability. Pointing ability has to do with the rig, sails, trim, and wind, in other words, the stuff above the waterline. Pointing is the angle between the centerline of the boat and the wind, apparent or true, depending on what you want to use. If one wanted to split hairs, then a feathering prop with less drag than a three-blade fixed prop would allow the boat to go faster (maybe .4 to .5 kts) and therefore the trim and pointing angle will be slightly different but this is probably miniscule and would be difficult to measure.Where the really BIG difference comes from is the tracking angle, the angle the boat is actually making against the wind. With the tracking angle, everything below the waterline is highly important, especially drag. Drag! That ugly, bad, DRAG!The more drag there is the more the boat will sideslip. You can see this visually by looking at a couple landmarks in the direction the boat is headed and which are one behind the other. Also, if you're tracking behind or in front of another boat you could see what the delta is in the angle between their tracking angle and your tracking angle. If you're behind another boat there will be a 'bad air' factor that has to be thrown in. If there is adverse current this can look like sideslip even though it isn't.Speaking of current, racing in our area, and probably yours too, one must take into account current and eddies as they are there to be used to your advantage.Frank - you did a good after-race analysis.
