We're very methodical and take our time, it's a forty-five minute process. The H16 takes twenty-five minutes.
From the storage yard, mast up, it takes thirty for the 18. Primarily because we do a lot of rigging in the water, tied to a dock, and the covers have to be removed and replaced and we do not leave our jib on the boat in the yard.
We can all say it only takes us so long to set one up, but lets face it, a catamaran takes a considerable amount of time compared to a monohull of the same size, but is the performance payoff worth it. Obviously!
If you have the opportunity for mast up storage I would highly recommend it. We pay $35/month, compared to other parts of the country this is probably dirt cheap, but it has greatly enhanced our sailing experience and is well worth our money. The trip to the lake is a little faster and at a lower cost for fuel. Also there is some wear and tear on the hulls during trailering. Oops, I gotten off the subject line of this thread.
