Ah, sorry I didn't mean to give that impression. The old ones did hold air OK; I was just trying to put a positive in to balance the picture.

The bow was mis-shapen and there were 'cosmetic' issues.
I am told that things changed when their QA was 're-organised'.

Shame that. I assume the replacement toobs are ok?

Yes, some relatively minor cosmetic issues that I live with, my fault for specifying swanky toobs but they do appear sturdy and air tight.

That's the important bit for me

One question for Etec owners, particularly Vipermax ones, what sort of fuel economy (litres per nm) do you get at displacement speed, steady cruising (20-25kt) and fairly near flat out? Just so I know what I am looking at - running costs are an issue.

Thanks

I reckon you'll struggle with this one.

Probably, but it is of interest to a surprising number of people - I've been asked a couple of times and I don't know the answer.

I'd have guessed that fuel consumption/Nm is very good in the lower part of displacement speeds 1000-1500rpm, worsening as planing speed is approached and improving again once on the plane?

My rib make about 2-3kts with the engines just in gear - it can't be burning much gas at those revs. I think
