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,
epirb, 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.
