Rich,

It is not a lack of coverage that bothers me, it is an ingnorance of the smaller boat builder - What do you class as a small boat builder???

I do not think Eco Cats are a small boat builder (unless you class the size of their boats) on the contrary they are quite large and popular with those that do not mind what they are looking at (the fashion conscious on the other hand do) and are extremely economical. PowerCats are (to my knowledge) a smaller boat builder, who's design are excellent and there are MotorCats, who IMHO are the market leader when it comes to styling and efficiency combined. Take the RIBcat for instance (I may be bias around about now), it is a great looking boat, which utilises a Hydrofoil - which means it only needs small engines (tein 50-70hp) to reach similar speeds to that of a similar sized monohull that would need one or two large engines (100 hp plus) to reach the same speeds. This is where your fuel efficiency comes in, smaller engines doing the same speed - you will go further i.e. more miles per gallon (I reckon around 30% further - needs to be tested though) You have not comprimised anything at all other than using less fuel to go further.

On the other hand, if we were to fit an inboard diesel, apart from losing some storage space, I would bet that the RIBcat would go even further, the weight of the engine may slow it down so you might have to use two small diesels but the fact remains Cats go further (so you don't have to - thats an advert somewhere) on less fuel, less weight etc....
