Thats interesting - is that an average, or have you used a GPS. Also many road based GPS's are not very good for canals as they round down to the nearest mph. Of course, the diesel heads amongst you, will know that old engines were rated by their bore and stoke sizes like steam engines. It is not equivelent to BHP. At a guess I would say my 19.2HP SR3 is equivelent to about 30 BHP. Of course when you do our sort of cruising you need every bit of BHP. For canals you can get away with 1 HP!! :-) Cheers, Mike nb. 1 horse on the land is worth 10 in the water - they don't swim to well when pulling boats along! :-) -- Michael Askin http://shoestring_DOT_zapto_DOT_org/
