Hi ,the Medina was a good boat, and as you say the reason it was fased out was the problems with the water jets,There has been some new testing done on the Ocean Dynamicks boat I believe.
Im Not sure what there outcome was,I personaly feel happier with the grip you get with a prop in the water, and the benefits of fuel economy and all up weight as a waterjet plus engine and gearbox makes it unreasonable at the other end.
Water jets have come a long way but in my opinion have advantages and disadvantages like all forms of boat propulsion.
As far as self righting goes lets hope nobody needs it,I was concerned when I found out that some ribs/and others boats were almost as stable inverted as they were the right way up.
The new regulation for compliance to the Recreational Craft Directives with regard iso standardes iso 12217 for stability for offshore craft clearly shows when analysing a vessel GZ stability curve what is good and what is bad,and puts the client in a better position to make a more informed decision.
My initial feeling was one of ,more paperwork UH, but I realised that it was for better to design and more seaworthy boat and all round safety,that in my opinion I welcome holehartedly for long distance offshore craft.
The days are gone when you looked at a new boat and thought thats got good lines,Its all computer modelling and stability tests, GZ results, Angle of vanishing stability ,downflooding angles,ect ect.
Still great fun though.
Thanks Mark for your comments,The Scorpian is a great boat, and I look forward to your constructive comments in the future.
Your right it will sell itself in fact the first one is already sold,I agree all ribs are just fantastick and I will try and moderate my enthusiasam.
It difficult trying to help RIB net clients know all the ins and outs of the boat building buisness as I see it, withought upsetting some body, as it is going through such a huge transformation at the moment,i.e Recreational craft Directive and implication,4 stroke/2 stroke,Diesel injection emissions,Grp and aluminium structures,Radar displays, vhfGMDss,etc etc.
I can only give my personal feelings on this ever changing monkey.In the hope that it helps others make informed decisions and question everthing they are told.
