This gave us the console position, and fuel tank position etc, so then under the decks we said the fuel need to go here so longitudinals and bulkheads here etc. Hopefully giving you a balanced boat..

Was the A-frame mass factored into your balance/COG calculations?

I was speaking with one of their technical people from Poole a few months ago re the 85. He was saying they are so light the RNLI are looking to lay lead ignots in the hull to increase their weight and make the 85's less skitty.
Have to say, having seen it afloat it really looks the biz !!!

skittish? lol its not a keel boat please tell me they didnt put lead in them! love the atlantics but they always seem underpowered compared to pleasure ribs (yes yes i know range and life span) but the 85s are brilliant. if they want to make them heavier they should just make em out of s glass using carbon fiber for the stringers etc not far off the same weight and strength but a shed load cheaper.

As well as the things you have already mentioned, its to stop throttle happy Helms just gunning the throttles and flipping them when they pumped up with adrenaline trying to reach the incident.

Looks like an interesting project.
Who did the structural calculations?

The idea was to make a 7m rib as light a possible but still being functional and robust. Adrian Thompson has designed the hull, the rib has been built out of carbon with a high density impact resistant foam. Half the reason for funds drawing short is the fact that no expense was speared on the construction and materials!
So the long and the short of it soon to be finished is a 7m rib with a 100HP Yamaha 2010 engine weighing in at 540kg. The handy thing about this is also that on the road trailer the all up weight should be less than 750KG!
There has been one other hull drawn from the mould, this had a diesel inboard added. The boat is amazing in heavy seas, better than Tornado ribs I have used in equivalent conditions.
Just thought I would share these pics with you, finished pics in a month or so!

But it does happen. Even just in error over one wave by someone experienced.

Looks like a very good project GBR1
