best starting place to get to block island
Try Point Judith Harbor of Refuge, RI bay 41° 21'' 55" N 71° 30'' 25" W . It should be about 10-12 nm to Block Island. Plenty of safe anchorage. Easy to get in and out. The town of Gallilee offers some great seafood restaurants or you can buy lobster right off the boats. Watch for the ferries that run out to Block from there.
