Pressures?

[Nasher]

This should be one I know the answer to having grown up around RIBs and SIBs, but it’s not something I’ve ever really considered.

I’ve always pumped up the tubes of my boats to whatever pressure feels ‘right’, based on what my Father taught me.

However, having recently been involved with the Smaller Nashers Bombard 380, and the Bravo pump I purchased to go with it, I’ve had to think about tube pressures.

Question is, what sort of pressure is normal for a larger Hypalon RIB?

I’m sure when topping up the tubes on our 6.5M Ocean I’ll have a go with the Bravo at some point, and of course having the facility available I might as well set a pressure.

Any thoughts?

Thanks

Slightly less than the setpoint of the pressure release valves I'd have thought. Can't remember what that is off hand.

[BumbleAbout]

I've always used 3psi for tubes & 11psi for air floors - although I guess that that the correct answer is "ask the manufacturer"

[Dry_Doc]

It should be in the manufacturer's handbook supplied with the boat.
The normal pressures on our Humber are 2.75psi

The manufacturers plate & the manual on our XS state 3 PSI

Thanks Guys

No chance of the handbook I'm afraid.

I'd be surprised if Ocean handed one out when the boat was new, let alone it being passed on when I brought it as an abused project 7 years ago.

Do you guys who buy new boats really get a handbook with it?

My 18' Polaris is spec'd at 2.5 psi. As I recall, my 14' Achilles SIB was 3 or 3.5 psi.

Bottom line: it varies.
