Tiger Too Preventer


Toby Ritter of Mamaroneck, NY, has a nice preventer rig aboard his Sparkman & Stephens center-cockpit 48-footer, Tiger Too. He sent us the following description:

Our preventer runs from the aft end of the boom, where it terminates in a Wichard Quick-Release shackle, forward along the underside of the boom through small guide blocks to the mast, then down to the deck, through a turning block to a deck organizer, and back to the cockpit through an Antal rope clutch.

Before going to sea, we rig flat nylon webbing from the bow cleats on port and starboard, outside of everything, aft to about the boarding gates amidships. The webbing straps terminate in sewn eyes (6000 lb. test) which are secured to the rail with light line.

To rig the preventer we release the preventer line from the clutch, take the shackle forward from the end of the boom, clip it to the loop on the webbing, and release the webbing. We can then trim the preventer from the cockpit without ever having to go forward on deck.

In a jibe, as the main is centered, the preventer is released from the webbing on the leeward side, walked around the aft end of the cockpit, and attached to the webbing on the windward side. The boat is jibed, the main eased, and the preventer tensioned on the other side from the cockpit. It works like a charm.

Two years out of Emory University, after a brief stint as a sportswriter, he set out from Miami aboard a 60-year-old wooden William Atkin ketch named Tosca. For 10 years, he and writer-photographer Theresa Gibbons explored the Caribbean, crossed the Pacific, and cruised Southeast Asia aboard Tosca, working along the way as journalists and documenting their adventures for various travel and sailing publications, including Cruising World, Sail, Sailing, Cruising Helmsman, and Sailing World. Upon his return to land life, Darrell became the associate editor, then senior editor at Cruising World magazine, where he worked for five years. Before taking on the editor’s position at Practical Sailor, Darrell was the editor of Offshore magazine, a boating-lifestyle magazine serving the New England area. Darrell has won multiple awards from Boating Writer’s International, including the Monk Farnham award for editorial excellence. He holds a U.S. Coast Guard 100-ton Master license and has worked as a harbor pilot and skippered a variety of commercial charter boats.
