Towser's Traveller

Towser's Harken track is an exact replacement for the original (the screw hole spacing is identical). The noteworthy feature is the use of Ratchamatic blocks on the coaming. If the weather cleat is accidentally released, the block below it locks and the car rolls gently to leeward.

The one deficiency compared with other solutions on this page is that the leeward side must be cleated before a tack or the car will run down to the new leeward side. The cross-haul, however, is continuous, so if the new leeward side has been left cleated, a tug on the line frees it.
