I wonder...Just how much diesel would a 45' Australian retired Cray boat use per hour at cruise speed, with a Detroit 510hp (92TT) powering the boat. I'm guessing she would burn 11 US Gallons (41.6395 Litres) Plus, Per hour at cruise Here's a link
to more information on the fishing boat.
I don't know for sure but I think I may be getting to be to old, 70, to stick with sail but, old coot or not, I'm fast coming to believe a light Trimaran of 37' to 42' would be a more economical boat for my needs, something like this
...Or this beauty.
