Cookee,

Is there a dental disclaimer absolving B-Shark of any claims relating to loosening of fillings, eyeballs and any uncontrolled breasts that may endanger the craft or become a hazard to marine navigation!?

I just posted a picture of a friends new 5.4m Bombard in another thread. When he was shopping for the boat, the dealer recommended a 60 4-stroke. My friend asked my what I thought and I told him I thought it would be WAY underpowered especially considering that we wants to take 4 divers out. He settled on the 75, but now wishes he had put the 90 on it... the max. rating.

When we went back to the dealer to order the 75, the dealer 'fessed up that he thought that that was a good idea and that the reason he had suggested the 60 was simply because he had it in stock and wanted rid of it. I think I would have found a new dealer at that point as he clearly had his own interest ahead of his customers...

So getting to the original question, I suspect it's partly the weight thing, but also the economics... It's always going to be easier to sell a less expensive boat than a more expensive boat, especially to a novice boater!

(Personally, I could never see the point of buying anything less than the max. rated, but that's just me!)

This is now displayed on a plate on all boats as well as a serial number which must be fitted on the transom. The serial number will give Country of Manufacturer, Month and Year of Make etc.This Standard covers all types of boats and was brought in to harmonise the Market & make boating safe for all.
Well I'm afraid nobody told me about that clause in the RCD. I could be wrong and so could the surveyor that does our CE work, but to my knowledge the way that the maximum HP (it's actually really usefully listed as KW not HP) is that the boat goes through some tests (they vary depending on the category) with the maximum HP on the boat and it is then approved for that HP.

Therefore if I wanted to put a 350 SCI Verado on one of our boats it would be a simple question of doing some tests at sea and proving it was strong enough to cope with the power and weight of the engine, changing the plate on the back and selling it.

Cookee I'm no expert but I think (from reading the MAIB report on the Abersoch accident a while ago) there are two ways to show compliance either you go down the mathematical formula route (described in some ISO document) as Graham outlined OR you demonstrate compliance by actual physical testing.

That's odd, the 5.85 I've just picked up is max rated to 120, the 535 however, a considerably smaller boat is rated to 90.

My Bombard Exlorer 6.0 is rated to 120hp and I have a 115hp 2-stroke but it is a 1998. It goes like hell with a cleaver 23"

So its a marine surveyor who is reponsible for determining the ultimate power capabilities of a hull ? He comes to your yard, ticks some boxes and gives you a plate (so to speak) to stick on the back ?

Original UK built 585's are rated higher than the later UK and South African built ones.

Any idea when they changed? the one I've bought is a 95 or 96. Have to say it looks a lot of rib to be restricted to 120.

Was it involved in the Dunkirk evacuations?
