Marty,
I made same trip 40 years ago on a 21 foot swing keel sailboat and had a great time! I suggest you think about being self sufficient. Do you have a GPS and charts, fog is not uncommon. Bell, horn, life jackets, flares and vhf are, in my opinion, required. Is the boat, motor and fuel confidence 100%. Do not expect to enter the water to retrieve a head sheet wrapped around the rudder or what ever, w/o a wet suit. Leave time on both sides if conditions are not optimum. Finally, plan your strategy for freighters. Of course I did not do any of these things and survived. Good luck.
Nick
