A couple of other considerations
I remember when I first entered sailing and brought my first boat. I explained to the dealer that I intended to cross oceans and go to Bermuda and do all of those romantic and adventerous things that I had been reading asbout all my life. The dealer smiled and said "this boat will take you there". It was a 25 foot Tanzer! Lesson #1: don't listen to the dealer.I really love my recently purchased Legend 35.5 but would not ever consider a circumnavagation with her--or any other hunter for many of the reasons listed in responses to your inquiry. They are not designed for a circumnavagation. They are, hewever, terrific boats for their designed purpose--near coastal and protected water cruising/racing.While looking for a suitable boat do not be blinded by "newness" and "glitz". And consider the two following factors: 1. can the boat be turned upside down and everything remain in place? (locker contents as well as locker covers, floor boards, batteries, etc.) 2. as you inspect the boat imagine it suddenly being UNDERWATER. In short, is the boat waterproof and is the gear secure from a sever knockdown. Then imagine your body flying around the cabin in 30-40 foot seas--the large roomy interiors designed into the Catalinas and Hunters are a liability in such a situation.I know this sounds like doom and gloom. A circumnavigation is an awesome undertaking requiring tremendous planning. Forget about those idiots who cross oceans in 22 foot rowboats. Undertaking such an adventure, with patience and proper planing, and the proper boat, can result in a wonderful voyage. However, IF THINGS GO WRONG there is nowhere to run for help. Surely you would want to be prepared for what you hope will never happen. I am not a circumnavigator and my boat serves me fine for its design purpose, however if I were looking for a boat for circumnavigating I would want a strongly built boat, but one that is not a "slug". I would want a newer design (as opposed to the Cabo's and Packets)and would consider, in fact seek, the advice of those who have been there.Good luck in your adventure.
