Most cat sailors started in monohulls and made the change OK
A couple of things to be aware of.
1. A cat doesn't heel over in response to wind
gusts the way a mono does. That means that there is nothing to relieve that additional force on the sails
You also don't get the same feed back of weather helm
when over canvassed.
So need to be very aware of wind
speeds and reef early. The golden rule
is "In a monohull, trim/reef for the average wind speed. in a multihull
, trim/reef for the expected gusts".
2. Don't try to point as high into the wind as you would on a monohull. Bearing off a bit will likely increase your VMG to windward noticeably as your speed picks up.
3. Manoeuvering under motor
is much easier once you get the feel of two widely separated propellors.
