Efficient sail handling begins with the selection of the correct winch. To help you select the correct Lewmar winch, the Lewmar chart on each page is designed as a quick reference to match application, yacht size and winch. Cross reference your yacht size (for masthead rigs) or sail area (fractional rigs) with application, to ascertain the correct winch.
Remember, Runner winch and Mainsheet winch selection depends on the purchase system fitted and expected loads. Dynamic sail loads can easily increase the loads dramatically. Multihulls generally have a higher righting moment than monohulls of equivalent lengths, resulting in higher dynamic loading, therefore winch size needs to be larger.
