I'd guess that you pumped it in the sun and then put it in cold water. Pressurising air warms it and causes it to expand, the cool water will have reversed the process. Try topping it up once afloat.

Over inflating that much could be trouble.. This is what puts me off the honwave air floor. Almost bought one as the quality looks there. The ali floored yam I have does not do floor flex in any way, even when slammed into waves at speed....

Can you carry a small air cylinder of some sort to top the floor up on the water, is the foot pump not able to perform (even on the inboard outlet for high pressure)...

A small diving bottle (reserve type ) pressurised to a low level by your electric pump's maximum output or standard compressor. (A tiny fraction of what the cylinder is designed for) could be used to top up the floor maybe... I thought about this pressure issue before I chanced across my yam and did not buy the honwave... What sized bottle would be needed to ensure a hard floor when on the water ?????? Could you make / buy an adaptor for the connecting hose to cylinder???? Could you use your electric pump from a small on board battery pack, this would be easiest by far??

Can it not be topped up with a simple manual pump once on the water?

Or is that too simple?

Just a question, when you say up to the recomended pressure, is that using bravos gauge (ie cut out switch) or did you take a reading from a seperate gauge?

The reason why I ask is that the bravos presssure cut out switch is unreliable, so you may think its up to pressure when it is not.

I must say that I have a 3.8m Honwave and have had no such problems with loss of pressure resulting from the boat entering the water, this includes launching at Ullswater, one of the coldest waters in the UK.
Best wishes

Jake
