All the best
I tried emailing the manufacturer with no reply.
Copied from the manual
Continue inflation with each valve in turn, so that you get a balance of pressure between each chamber, until the boat is fully inflated. Inflation pressure is 0.25 bar (3.6 PSI) for the main tubes and 0.35 bar (5.07 PSI) for the keel. This reduces excess tension and results in a longer service life. Remember to include the keel and the floor in this sequence.
Installing the floor
Lay the floor in the boat.
Position it so that the back end is square with the transom, and the front end has the keelís inflation valve centred on the hole that gives access to it.
Push the edges of the floor under the tubes.
Check that it is spread evenly over the base of the boat.
