NEsurfer from United States

“The waves suck here. Fat, inconsistent, with no power or push behind them, all the good hurricane swells are blocked by the cape and islands and there are huge rocks just inches below the surface. Barnacles will cut you open and cause nasty infections, or you may break a toe on one of the 1000's of rocks that cover the bottom. Better off going to Nahant or Marblehead or even Nantasket for better surf.”
