I agree with Phillip.
If you are going to be singlehanding
a great deal of the time, 50 feet of catamaran
is a massively huge yacht to handle. It's not impossible for one person to run a yacht that size. But it's a lot of work unless you have crew to assist and maintain the yacht.
I know that I can easily handle our Privilege 39 singlehanded. I have already done it all over the world, but the boat was a handful.
If you hire full time crew, then there's no problem. But when you are sailing among the reefs
in the South Pacific
, and when the situation is touch and go, you could get into trouble really fast if you are sailing short handed.
If you are sailing around the world in the roaring 40's, then a big cat that is set up for singlehanding
would be the way to go. But if you are doing typical cruising in tight anchorages
heads and fellow cruisers all around, you will have many sleepless nights worrying about how you don't have enough scope
out to hold your massive yacht in a crowded anchorage.
you decide to go, good luck on your adventure
