The CCC is More Scenic, Safer...
...and protected. It just seems a safer way to go. Just plan to pass thru Wood's Hole at slack tide (please be careful, anyway) and go with the flow of the canal on through (flows East on a rising tide). If the tide is against you (possibly 4+ knots), there's a 9-10 foot tidal drop from the East to West, then DO NOT take the canal, but pull into Onset for the night (anchoring, moorings available) and take the morning tide thru the canal. Sandwich Marina on the East end of the canal is also a good take if the weather/tide/daylight don't cooperate.If from Nantucket, and if you must go by the outside, you might hit a strong head tide all the way to P-town. You don't want to do that. Stay on the inside (CCC) and you will be much safer.P.S. The yellow Eldridge book will be very beneficial in guiding you throughout the region and is available in most marine stores for the same price ($12.95).Pay close attention to the CCC rules for sailboats and you will be golden!
