They only bother you when you are on shore...my theory is stay on the water and you will be just fine.
We camped in that area last summer about the same time last year,as soon as we stopped(in a jeep with no top) we were assaulted by hundreds of super aggressive blood suckers:shock:.It was so bad we had to make a run for it.We found a little resort/store and got some 99%deet,I think it was 8 bucks a bottle.took a nice stinky shower in the the stuff and it kept them from landing on us, but they continuously bounced of our skin,almost as anoying!Now I always keep a bottle in my survival kit thats with me whenever I am out adventuring!
