240 Cruise
It is all in the definition of off-shore sailing. Conditions can change quickly no matter what they forecast (guess) so like all things you need to plan for that. Off-shore blue water and days away from a harbor, no way (not designed for it not intended for it), off-shore and be within hours of a harbor yes way (and done many times). Have done it in boats a lot smaller than 240's. Just the other weekend headed off James town RI in the 240 on the same tack for several hours, Azores here I come, pure heaven. Left early am, turned around at noon, winds stiffend as expected and in at point Judith on dusk. Had block as backup harbor, sailed the area many time and would not be comming in to new areas after dark etc. Yes, there are some places on the east coast not even "off-shore" where I do not want to put myself or my boat. also need to have time on your hands and not be in a rush to get somewhere and head off when the conditions are not right. Plan well and enjoy your adventures.
