WINCH SELECTION
Choose your Andersen winches to suit the type and size of your yacht and your sailing
requirements. This selection guide is intended for masthead rigged monohull yachts of
medium displacement. Refer to the notes to the right of this page regarding other rig or
displacement types.
Please note that this table lists typical winch sizing for the given applications, but cannot
take into account all variables due to the wide variety of sailing vessels and conditions.
For electric or hydraulic winches, the size selection is generally similar to that of
a manually operated winch.
For further details see our website at www.ronstan.com or consult your local
Andersen winches representative for assistance in selecting your winches and
information on features, options and installation.
LOA (Metres)
LOA (Feet)
Masthead Rigged
Use the length overall (LOA) figures as your primary selection criteria.
Fractional Rigged
Refer primarily to the sail area rather than LOA.
Heavy Displacement
For boats with heavy displacement and/or a high righting moment, it is advisable
to choose a winch larger than those indicated in the table.
Multihulls
Catamarans and trimarans have higher righting moments than monohulls of the same
size and should use winches larger than those indicated in the table.
