If I had unlimited funds, I would only sail very high performance multihulls. When I go on OPBs, its virtually always a very high performance multihull
The thing is, I do have a specific, finite amount of money
, to buy, to operate, to maintain, to and to live on.
In order to live and cruise
, there is an amount of volume, and an amount of payload mass: living space and weight of people, clothes, dinghies, fuel
The cheapest way to enclose that volume, and provide the water
plane area to absorb weight changes, is a monohull
. The closer to a sphere, the better: minimize surface area (construction material), maximize moment of inertia, and therefore minimize the amount of structural material. Therefore, the least material, the least weight, the best performance potential.
Yes, performance is dominated by weight, far more than shape.
We all know that most cruising boats are pigs to sail. Way, way to heavy, too much wetted surface, too little sail area, and generally horrible helm
feel. Nice helm
feel is exemplified by Soling or Tornado: light, responsive helm, where the performance changes quickly, so its fun to sail, instead of just a slow, expensive, uncomfortable way to get around.
Also, the secret of sailing multihulls in big seaways is to keep only one hull
in the water. That really drives the load and cost through the roof, and eliminates any sort of "comfortable cruising."
So, while if one was comparing off-the-shell cruising boats, such as Gunboats, Lagoons, Farriers, Jenneaus, Hunters, Hinkleys, and so on, they all are such horrible trade-offs: Gunboats and Farriers are fast and fun, but only if you have an unlimited budget
and/or don't take anyone or anything with you; The others -- mono or multi -- are sluggish pigs.
Therefore, for me, a mono is the way to go. But a custom mono, not one derived from a race
boat (such as a retired TP52, say), or designed to look like a race
boat but handle like a barge (all production monos and multis this side of, say, a Gunboat).
Custom mono so its very light, so the loads are very low, so its very fun, yet can still carry the volume and weight needed, at the lowest cost to build, own, and sail.
