Leading halyards and control lines aft to the cockpit allows
crews to raise and lower sails or make tuning adjustments without moving to the
mastbase. Because space is limited at the mastbase and on the cabin house, a
variety of specialized blocks have evolved for routing lines aft.
Typical Boat Length:
Small Boat: 22' - 28' (6.7 - 8.5
m)

Halyards Smaller boat under 30'
(9 m) often lead only the principle halyards aft. |

Halyards: Larger
boats use special mastbase halyard lead blocks (A). Lines are routed out to
deck organizers then aft to stoppers and winches. Stand-up blocks on a base are
sometimes preferred for their complete articulation, but they hold halyards
higher off the deck than specialized mastbase blocks. |

|
Halyards: Modern
race boats lead halyards and control lines straight aft through deck organizers
so they can be used on either cabintop winch. |

|
 |
|

|
Over the Top: Special blocks are
required when lines must route over an outside corner like the front of a
doghouse or coaming. |
