The year I decided to use the Renesub Spearguns exclusively, I won the North Atlantic Championships. To win the Championship and earn the very pompus title of North Atlantic Champion, well it sounds grandiose, you have to accumulate the most points during the Open Competitions of the North Atlantic States that have a counsel. In 2009 and 2010, I had to compete in the New York Open, Massachusetts Open and the Rhode Island Open. I won both years. In 2011 I was busy kayaking from Miami to Montreal (http://miami2montreal.com). It took 114 days.
I think the gun with its extra range enabled me to score some very decisive points.
