Ordered some beaver tail float pods (from Walmart.com of all places) $250 for the pair. Had the local Welding school slap them on there and tada!
I'm pretty pleased on my initial trial. Seems to have a lot more buoyancy in the stern. It rides a bit higher. Cuts the same. And yet much more stable.
This 1979 1756 polar Kraft has been a 100% makeover project. My father bought the boat the year I was born. Not much remains from the original, but I don't plan on selling it anytime soon!
