[PCW] fuel economy

[John Holbrook]

Hi Robert, 
 
Thanks for the response. The bit about wetted surface resistance vs wave-making resistance and speed is new to me and makes sense. I was under the impression that some power cats were very fuel efficient and capable of crossing the Atlantic, i.e. 2000 nm range in the 10 - 12 kn range.   

Yes my boat is not efficient at 10 kn and will not reach 12 kn but a 1000 nm plus range is the deciding factor for me. You mention that the manta will travel at higher speeds reasonably efficiently, i guess that is subjective and depends what type of boats you are comparing it with. 
 
>From a different perspective with fuel prices increasing the resale value of boats in 5 years may be greatly influenced by their fuel efficiency. 
 
For the record the Manta looks like a great boat and that fact that I'm using it as a benchmark here is because it is what data i had available for this genre of boat.  
 
Cheers
