Shorediving NewEngland is abundant, rich w/ life that can be quite different. From July to October you can find juvinal tropical fish from shore in R.I.. The Cape Ann...Gloucester and Rockport area have terrific sand entry or granite entry dives that can get as deep as 80 ft. The granite bottom carved out from eons of pounding waves is beautiful in places, it gives you small cave oportunities, swim throughs, dramatic ledges, and nooks and cranies for lobsters and other critters of the deep.
We rarely have currents that are trouble. The Cape Ann area has North, South, and East facing dive spots so whichever way the wind is blowing on your weekend you can still dive.
Fish life you will frequently see... flounder, tautog, sea ravens, curious Large stripe bass, dog fish, skates, sculpin, anenomes "Northern Red anenome" occasional ocean pout, wolffish, and atlantic torpedo ray "electric ray". Did I mention Lobster. They are everywhere and can grow as large as 20lbs, athough you can take nothing larger than 5lbs home to dinner.
Another diving opportunity not yet mentioned is the Isle of Shoals area off the coast of N.H. It is home to a large number of sea lions/seals. The Isle of shoals is a boat dive, another different boat dive offered out here is scallop diving.
Hope to see you out there. Sid
