Doug, I agree with you about Ingram's sponsons. After following the thread on Paddlewise, I decided to buy a set just to see for myself what this was all about. I found the sponsons themselves to be a quality product, but Tim's method of attachment to be problemmatic, so I rigged my wooden kayak with small permanent attachment points and set up my own rig to affix the sponsons to the boat. Worked very well--the gained stability is remarkable. Meanwhile, I continue to speculate on a better way of affixing the sponsons such that they could be swiftly deployed on a standard hardshell kayak without needing to affix hard, permanent attachment points.
But Ingram has chosen a confrontational, quasi-libelous full-attack mode on the entire small-boat world, with the results that anyone would expect. In my opinion, he is more interested in triumphing over his foes than in selling sponsons. Maybe small boat safety would be better served if he turned over his interest in sponsons to a neutral party, so that their merits could be more advantageously be exhibited.
