Dinghy inflatable floor pressure

[JerryHawkins]

Dear All,

I've recently replaced my ageing (and now fairly porous) inflatable dinghy with a nice new one with an inflatable floor. The pump supplied (styrrup type) has a pressure guage - but what pressure to inflate to? When I use my old LVM 12volt inflator, the whole thing is still rather limp and I have to "top up" with the hand pump!

Using about 1.5 psi for the tubes and 3psi for the floor seems about right, but the keel still seems to push the floor up a bit. Does anyone know the recommended pressure? Has anyone "burst" their floor (or tubes) through over inflation!?

Cheers,

Jerry

I pump the floor tot he max with a standard foot pump on my palastimo 265i, then the keel until the floor shows sign of flexing. Floor needs to be firm to do it's job but the keel is just as effective slightly 'soft', and is clearly of a weaker construction than any other part.
Hope this helps

I have a quicksilver inflatable with inflatable floor.The tubes and keel are inflated to about 0.2-0.25 bar and the floor to about 0.7-0.75 bar, these figures from memory as the handbook is on the boat. The electric inflator almost manages the lower figure but the floor requires considerable extra effort with the hand pump to achieve the high pressure. If its a short low speed hop I don't bother with the high pressure but it is worth it for anything more than that. Not sure if all makes of inflatable have high pressure floors.

The floor on my AX needs about 8psi which is a good hard push with the stirrup pump. The electric inflator is normally good enough for short trips.

Thanks all!

Thanks for that - mine is a Quicksilver, so I'll give it another go this weekend. 750mB is over 10PSI - no wonder the floor was still quite flexible at only 3 or 4 PSI that I used before!

Cheers,

Jerry

Re: Thanks all!

Quicksilver aerodeck should be 12psi, the pressure gauge will only register when actually pumping and not "at rest".

Zodiac quote 11.4 psi, if I remember correctly, for their infaltable floor.
