Floor pressure

Hi

My boat (Chinese one) says main tubes need to be 3.6psi and keel 5.07psi
What do you think the floor needs to be? 3.6psi?

It doesn't say anything about floor in the instructions

I have a sib and the recommended pressures are
Tubes 3.1psi and floor 9.1psi.
The floor provides the rigidity needed to provide stability

Thanks. Maybe I should do the same.

My instructions say this

Inflation pressure is 0.25 bar (3.6 PSI) for each of the main tubes
Inflation pressure is 0.35 bar (5.07 PSI) for the keel.


It's a Trans-E 320 (3.2m)

I think I will put in 8.7PSI and see how I get on

Thanks

James

No idea re the Trans-E, but my Quicksilver has 3.6psi tubes, 6.4 psi keel and 11psi airdeck.

No idea about your boat, but you need to find out as correct floor pressure is crucial to the boat's performance. Not enough and it will be floppy, too much and it will burst.

Have you tried emailing the manufacturer or the importer? Alternatively tell us the exact model and someone on here might know.

All the best

Pete

Hi

I tried emailing the manufacturer with no reply.

Trans-E TS320

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.

My boat performed like an ole sow. Finally called the distributor. Told me to fill until the floor and keel and tubes feel hard. Tubes have pressure valve to keep from over filling them. I always thought the keel was too soft filling to the chart. They said to use a hand pump to top them off, not an electric pump as they can go too far. .
Even the directions in their web site said to fill until hand pump was difficult to push down. Said I didn't even need a gauge.
I did that THEN checked with a gauge. Surprised how much more air was in floor and keel compared to what the chart said. Tubes about the same. Finally figured out the max on the chart was with filling with an electric pump then use your hand pump to finish off.
Wasn't even the same boat when I took it out. Planed and ran better than ever. No ill effects on boat from doing it their way.
