Hoping some of you familiar with New England waters can provide some guidance. We are headed to Block Island then Nantucket then Martha's Vineyard then to Montauk. When I run the auto route on my chartplotter I get routes that look like what I would expect....EXCEPT, the route from BI to Nantucket takes me south of Martha's Vineyard. While that me be more direct there does appear to be some skinny water that way. For those of you that boat in these waters which way would you go from BI to Nantucket, north or south of MV? Thanks.
