Hi Fred,
As a regular user of these boats I have to agree and slightly disagree with you, they are superb value for money but if you are carrying camera gear then you may need to adapt a bit.
There is usually a table somewhere on most of the Tornado fleet - it may just need a word to one of the staff to get them to clear all of the accumulated 'stuff' from it.
The rinse tank on any of these boats is a danger pit best avoided anyhow, by the end of the week I have often wondered if a muck dive in the tank was a viable option - I am sure something moved in there..... For me most often a quick hose down with the shower on the rear deck is a better bet.
I have a trip in a few weeks with Alex Mustard on one of these boats and like last year there will be a full size DSLR with each guest ( often more than one ), think we are on one of the smaller boats (Whirlwind ?) with only 14 guests but it is quite workable.
