F-Ribs And Sibs - Inflatable Boat Community

Not having a battery pump and not wanting to use the foot pump to top up on the water.

What pressure are you guys putting in the inflatable floors to over come the cold water?

Normal is 11.6psi

I don’t recommend going way over pressure on the floor, but @harrison pumped his up to over 1 bar and it was fine.

I find I loose about .15 to .2 bar (2.17 to 2.9 psi). So I guess you would have to go to over 1 bar (14 psi) to stand a chance.

However - you are using a foot pump so your air going into the boat probably isn’t as hot to begin with so won’t lose as much.

You will need to do some experiments.

Cheers Chris.

That’s a lot more than I was expecting! I do use elec pump, but only run off car.

I’m out on it tomorrow so will have to have a look, although putting the honwave gauge on the floor valves is a pain in the arse.

Ha Ha! Yeah, not recommended. We whacked in more pressure to try and bottom out the cause of severe ventilation issues...all to no avail.

Inflated to 1 bar with the electric pump ashore, and this was the pressure after half an hour on the water.....Oooer!
