Lewmar Ocean Size 0 traveler systems are appropriate for boats up to 28' (8.5m) when used with an end-boom mainsheet. If the traveler
is installed on the cabin-top for a mid-boom sheeting arrangement it is only suggested you use a Lewmar Size 0 traveler on boats up to
24' (7.3m). The same reduced size limit is recommended for multihull sailboats because they have higher mainsheet loads than monohulls of the same size.
