Dose the ally tube shape offer any buoyancy
of course-in the same way that an oil drum does when ya build a raft for charity runs. The upthrust is equal to the weight of water displaced.
I was asked to test a new one of them down in Bristol years back but wasnt prepared to drive down there and back so they got a new boy with no knowledge of ribs but hungrier for the fee to do it
Seemed ok from the report that appeared in the angling mag, but then again never trust magazine reports esp when the manufacturer is also a fee paying advertiser
Must be b**** cold on the bum sitting on the toobs in winter
