OK, as I see it, there are 3 solutions to the Helium Dilemma-
1- Fill your boat with Helium. In my case that would be about $80 and would gain 8 1/2 lbs of bouyancy and would allow my loaded boat to float approx 1/50 of 1 inch higher in the water. So far so good? However, as helium sneaks thru hypalon and PVC faster than air, I need to carry a tank to top off my boat every morning. What does the tank weigh, maybe 20-30 lbs? That's no problem though, 'cause I'll need that tank when I bleed off excess pressure in the mid-day sun and add it back later in the day. Oh wait a minute, I guess I lost more than I gained due to the weight of the tank. That leads to #2-
2- Leave a 12 pack of beer at put-in. That of course is not an option either. Besides, the Buzzards will drink it.
3- Get one of these, tether it to your boat and put that spare 12 pack in it and let it follow you down the rio.
