text: Turns of shock cord, securing tack to centre of forebeam, stretch as the wind increases. This allows the jib to move up, frees the halyard slightly so the tack and peak move away from forestay.

text: The advanced design of new cats makes pitchpoling less likely. The treacherous forebeam is gone, and the new hulls have been engineered stronger to resist twisting under stress.

text: If using an all-chain system, then also utilise rope with the stretch in the bridle arms and have a 'lazy loop' of chain to act as a catenary between the bridle attachment and the forebeam. The minimum length of anchor line should be five times the height from the forebeam to the bottom at high tide.

glosses: A horizontal spar across the bow of some sailing vessels, used to stabilize the hulls of a catamaran, to secure a bowsprit, or to tie down the tack when there is no bowsprit.
