Typical Boat Length

Category Boat length
Small boat 6.7–8.5 m (22–28')
Midrange 8.8–10.4 m (29–34')
Big boat 10.7–12.8 m (35–42')

Part numbers are the hardware most commonly used for each layout.

The Four Layouts

  • 1 Halyard: a simple system that leads the main halyards aft. Used on boats under 9 m (30').
  • 3 Halyards: larger boats use dedicated mastbase lead blocks; lines run to deck organizers, then aft to stoppers and winches. Stand-up blocks on a base give full articulation but hold the halyards higher off the deck than dedicated mastbase blocks.
  • 6 Halyards: race boats lead halyards and control lines straight aft through deck organizers, so either cabintop winch can be used.
  • Over-the-Top: dedicated over-the-top blocks route lines over an outside corner such as the front of a doghouse or coaming.
