Lewmar Size 1 Ocean Traveler Kit - 4:1 Purchase System

The Lewmar Size 1 Ocean Traveler Kit with 4:1 purchase system is a compact, efficient rigging solution designed for cruising sailors and power boaters who demand reliable deck hardware for halyards, sheets, and general deck work. This kit is built by Lewmar, a reputable name in marine engineering, ensuring that it delivers the mechanical advantage needed to handle heavy loads with minimal physical strain.

The 4:1 mechanical advantage means that every pound of force you apply at the load becomes four pounds of pulling power, a principle that has proven invaluable to sailors for centuries. Lewmar's Size 1 is engineered for mid-sized applications where weight matters and deck space is limited, making it ideal for vessels in the 30–50 foot range or as auxiliary tackle aboard larger craft. The system employs proven block-and-pulley geometry with low-friction sheaves to minimize rope slip and energy loss.

Cruising sailors, charter boat operators, and commercial fishing crews benefit most from this configuration, particularly those working shorthanded or operating vessels in tight quarters. Its compact footprint—just 0.75 lbs—means you can carry multiple kits as backup or redundancy, critical when safety and reliability are non-negotiable on open water.
