I have to agree with Paul Blais, that's a fairly big leap unless you and / or your sailing buddies are already used to 50 footers. I sometimes take out an elderly one off “Whitbread Cup” 50' racing
cruiser and I can assure you that it's not an easy boat to handle solo.
On the engine
, without a bow thruster, the thing handles like a giraffe on roller skates and mooring
on the pontoon in any kind of breeze is an adventure to say the least. It makes my own 40 footer seem well behaved so based on my experience, unless you are already expert on boats of that size, I would strongly advise you to spend some time crewing
on one before you spend your money
