Marine Street can have a hefty surge. I used to live up the street and surfed Windansea for years in the 80s. Marine St. had some good body whomping waves.
I went hooping at Marine St. this year and got hammered coming in (at 4am). I had only been kayaking a month, so I was inexpereienced. I got pummeled by some set waves and had to gather my gear all along the beach from Horsehoe to Little Point.
Never tried launching there since - or during the day.
