Boats and personal watercraft are a large investment, so protect that investment with a Lunmar boat sling lift. The Lunmar boat lifts are constructed with longevity in mind. Drive pipe supported in 4 locations, 1/4" galvanized cable, and 14" slings are just a few of the features that separate these lifts from other popular brands. Lunmar uses aluminum sheaves instead of galvanized sheaves to increase durability. Pulleys are permanently lubricated, making hoisting and lowering your boat a breeze. Mounting hardware included.
