TAMING A CAT
There has been a huge surge in the sales of performance multihulls. The market for these boats is broadening; multihull cruisers are upgrading, monohull sailors are upsizing, and even virgin boat owners are tempted. Over the last 12 months, while coaching for Outremer, I’ve met hundreds of these owners, everyone from young families to retired couples moving aboard a new catamaran and setting sail on a circumnavigation. Handling a performance catamaran is achievable even for a novice multihull sailor. But there is a big difference between just ‘getting by’ on such a boat versus sailing efficiently, safely and in style.
The transition for even experienced sailors can be quite a step up. For a seasoned monohull sailor, the differences are obvious: increased volume and speed, and a lack of heel. Even for an existing multihull sailor, the handling and performance is noticeably less forgiving and requires a shift in focus and technique.
This winter, I set sail on a transatlantic with the new owners of an Outremer 55. They have previously owned another less performance-orientated catamaran but invited me on board to coach them to fine tune the boat, assist with routing, and help them take best advantage of all the performance their new yacht offers. Here are a few of the topics we focussed on:
SPEED
Most non-planing monohulls will do approximately the same speed on all points of sail. However, a performance multihull might sail at twice, three, even four times its upwind speed on a reach.
For example, the factory polars of an Outremer 55 give its average speed in 20 knots of wind with a true wind angle (TWA) of 50° at 8.5 knots, but in the same windspeed with a TWA of 110° it’s 19.1 knots. That’s more than twice as fast. How do you make the most of this speed advantage? And how do you best manage it?
