the bigger question should be, how well you know the other two...and will you trust them with your life? Other than a day of sea sick or two, it should be an experience to remember. Books are good, iPod will only last a few days at best, so plan accordingly.
Crew of Three is a bit shorthanded for a 50', IMHO.
I, with the advantage of old age and able to look back, would go in a heart beat. I would however get my affairs in order and call defender today and order up my own personal ditch bag, VHF
, and MRE kit, watermaker, plus all the other safety kit they would suggest.
I did do the Marion to Bermuda, unprepared, way back and had the time of my life. SO much so, I went back and did it again and again for a few years. My family nearly croaked.
I also took off from Melbourne, FL for the bahamas one day and found out that the skipper was less experienced and less prepared for weather than I was - I was able to prevail and return to Melbourne after being in the washing machine, 28 footer, for a day.
Best of luck, but if you decide to go, do get the safety gear...I NEVER, even now, depend on others for my gear or do without the basics.
