From time to time I have heard about a spot off the NH Cost that can break 15-20 feet. Its not in paddle distance but apparently if you know where to look you can see the breaking waves from shore. That is all I know.
Are you thinking off this spot? Its just south of Geness beach outside of the best left point break in NH. Not gonna say the actual spot. There enough douche's clogging it up enough as it is. These pics were taken 12/14/2010
