So I am assuming that all the good seamanship actions are taken - just looking at the one variable - the displacement
of the boat. I am talking about comparing say a 7 ton boat to a 12 ton boat both about 46 feet.
I have been reading your web site tonight and found it fascinating.
My fully loaded Privilege
39 weighed ten tons when lifted out of the water
in New Zealand
. So my comments are based on my experience with ten tons of catamaran
that are 39 feet long and twenty-one feet wide.
From my personal experience, I would not be so much concerned about the displacement of the catamaran
as I would be about the strength/quality of its construction. If the lighter and heavier displacement cats are all strong and well-constructed, I would be happy to cross oceans on either of them.
The principles of storm managment are the same. It's just that some designs are capable of higher terminal velocities and faster acceleration. At the low end of the spectrum, you can't go slower than zero knots. So drogues and parachutes work their magic in the same way at the low end.
Fast cats are more dangerous in the sense that they have more kinetic energy that you must control at all times. If all that energy gets out of control, bad things can happen. Capsize
, pitchpole, and structural damage are extremely poor ways of dissipating uncontrolled kenetic enery.
If I was on a fast cat sailing at high speeds in marginal conditions, and I wasn't going to slow down, I would have someone standing in the cockpit
with a sharp knife next to the mainsheet and someone standing next to the genoa
sheet ready to cut the sheets
if they should jam in an emergency
. Again, it's not rocket science. It's common sense.
If I was on a fast cat, I wouldn't ever let things get to the point where I needed to carry around a knife as part of my sailing gear
For me, displacement would not be an issue. No matter what the displacement, I would sail it in a manner in which safety
was not a problem.
Even if I had a Gunboat catamaran that sailed at twenty-five knots, it would still probably take me ten years to do another circumnavigation
