excel inflatable floor 0.7 bar

Reading my manual on the Excel sd 330,it says to inflate the floor to 0.7 bar pressure ,i got as far as 0.25 and that was hard,should i go to 0.7 bar pressure,seems a lot to me.why so hard just for the floor.

I would be phone them and ask the question of the excel team, however air flops are usually a higher pressure than tubes.

Have a look on the Transom plate, that should tell you

Yep, floor is high pressure so 0.7bar is spot on.

Floor gives a huge amount of rigidity to the sib, floppy floor equals rubbish performance

What was morning pressure topped to, will not remain same in the afternoon, will need a re inflation if wanting same morning water performance. Heat and atmospheric issues.

Happy Boating

Hi,thanks everyone,still learning about SIBS,never realized just how important the inflatable floor is to the rigidity of the boat and performance,and if its being used all day ill come in for a top up of air for it,unless i`m just fishing close in then i don`t suppose it matters.
Just hope its strong enough to take the 0.7 bar,and that the auto shut off and gauge is accurate on my Genovo pump(the yellow one with digital readout).
Thanks again
Chris

Even with just a few psi less than it should be, air floor boats are terrible. A bouncy floor can ruin the boat, water over the back, water over the front, might not even plane etc etc

Its important that you top up the floor and tubes once the boat has been in the water for 10 mins, the temperature change can cause a huge pressure drop in the boat.

Sorry, cant give advice on your pump, but I use the bravo ones and they are spot on. The only way to find out is to try it

Mine takes 0.75 BAR (11psi). Floor pressure is essential to get right for planing performance - not an issue at displacement speeds. I have to be careful - my pumping "system" is a SCUBA cylinder and can fill to 230 BAR

Looks like i am going to have to take the pump with me,may need a seperate pressure gauge to check against the pump reading,never knew there was so much to it,thanks again for all your help,0.7 bar seems common for inflatable floors looking on here,looking for a launching spot now.
Willk be carefull with that cylinder.230 bar my pump goes to 0.8 bar I believe.
