Yam 360s tube pressure

What would be the tube pressure and keel pressure recommended for this sib?

I had one of these but cannot remember - great SIB's. Presuming the hardfloor then you can go a bit lighter on tubes maybe but usually 3.2 to 3.4 psi in a SIB. Keel cannot remember but someone will...

I'd just say though that the range given there for a SIB is not right at the low end for sure.

Very different on a RIB to a SIB though - they can be run more like 2.5 for a softer ride as the hull gives the stiffness and strength with the tubes cushioning the ride and lower pressure makes it more supple and forgiving. Another disadvantage of a SIB in this respect!

Fenlander will be along with the keel pressure I'm sure we're all getting to old to remember these blooming figures...
