I have two rigid kayaks and this year two tolls was cheaper than the BCU, just, but quite honestly I am opposed to the free access across the UK as there are some waters, the upper Waveney & upper Wensum that. conservation wise, would not benefit either from canoe access nor the car parking and access being demanded by the BCU. I was actually on a Broads Authority consultation group with the BCU & I did not like their sheer militancy and all or nothing demands. That aside, I saved a few quid!
Snowy, at 17 stone it not the likelihood of the back end being under water but the middle going down and the two ends going up! Yes, it happened to me at 16 stone! You really do need to have maximum inflation for rigidity. My brother in law has a Sevylor, several years old now, he's well pleased.
