Spreader Rake is measured between a line between the tips of the spreaders and the back edge of the mast (as shown diagram 1).

    Helm is directly related to rudder rake and if you have too much weather helm (pull on the tiller) then the rudder may have to be kicked under the boat more and if you have neutral helm it may need to be raked aft. Hobie University, NAHCA Page 26...

    Rick White and Mary Wells have contributed a collection of performance sailing questions, which are used in their famous ‘Rick White’s Sailing Seminars’. These true or false questions are included in with Hobie U. to generate thought and discussion. If you disagree or don't understand a question, ask the opinion of others or read Rick &...
  • Page 52 Upper battens may need to be a little tighter on tapered comptips such as the Hobie 18. If you must over tighten the battens to get the sail to take shape, either your battens need to be sanded to reduce their stiffness (Tuned, see performance manuals) or your sail has stretched and needs to be recut to return it to its original shape.
  • Page 53 (like shifting into low gear) and sailing slightly below a close hauled course which also helps with power. As the boat accelerates, sheet in smoothly and bring the boat up to a close hauled course. Page 48 Hobie University, NAHCA 31 Mar 02...
  • Page 54: Boat Handling

    To accelerate from a dead stop, with sails luffing, the crew should bring the jib in first, then the skipper should bear off a little to a close reach and after gaining some speed, begin sheeting in the main.

  • Page 57 11. It is extremely important to have total control of your boat on the starting line -- being able to stop quickly, accelerate quickly, hold a position, backup and generally maneuver in tight traffic. Page 52 Hobie University, NAHCA 31 Mar 02...
  • Page 58 14. When you are the leeward boat, you need only hail "Up, up, up" many times and loud, then hit the other boat and he will have to do a 360. False. You must give time and opportunity, and avoid the collision. Page 53 Hobie University, NAHCA 31 Mar 02...
  • Page 59 If you draw a perpendicular line off your sterns, then any boat, or part of a boat that is forward of that line would have inside overlap. False. Tricky question, only those boats on the mark side (Port in Hobie Racing) will have inside overlap, the others are outside.
  • Page 60 The favored end is the end closest to you coming from the leeward mark. True. The favored end for finishing is the end farthest down wind, which is the end closest to the leeward or C mark. Page 55 Hobie University, NAHCA 31 Mar 02...
