Kev/Mark
Probably shorty cag/tee shirt, we tend to take a change (long thermal, cag) in a drybag, stacks of storage space in long boats(I'll probably have cooker, kettle, armchair, spare clothes, first aid kit, repair tape, multi tool all stashed in mine.)
197 sherpas may well be ok, however seayakking tends to be easier with a longer paddle, both Nigel & I have spare paddles. one of those could bre borrowed, we only really need one spare set /group.
