IC37 Class Coach Tips

Tips from the Class Coach © IC37 Class Association

One of the unique parts of the IC37 Class is access to our Class Coach, Moose McClintock. Here are some of Moose's biggest takeaways after his first season coaching the class:

  1. The main is a lot fuller than you think, if the main is too deep low and the traveler is too high, the boat just heels and goes sideways.

  2. You need more outhaul than you think to keep the lower leech open and allowing firmer trim.

  3. If the main is set up full, plan on twisting more and having a slightly lower upwind mode, the speed gained gets the height back but it makes it increasingly hard to live in a lane so have a runway, to get height go slightly firmer on main.

  4. In light to moderate wind, boats that try to live in a lane with the boom more than a few inches above centerline and a tight leech fall into the leeward boat faster.

  5. Fore and aft weight placement is critical depending on breeze, the transom really drags in light air so weight has to be extremely far forward, as soon as you're depowering the weight has to be aft for hiking power.
