Trim Techniques and Effects

Trimming weight (hull trim)

  • The crew should sit out so as to maintain the mast vertical. The boat will go faster and drift less to leeward.
  • Crew sitting forward: in very light winds reduces wetted surface resulting in less friction and more speed.
  • Crew sitting aft: with strong winds and waves, easier control; the boat is encouraged to ‘plane’; under spinnaker aids in balancing the forward force on the mast.
  • Crew sitting to lee: with very light winds, maintains the sail belly stable so as to catch every puff of wind.
