The bottom of the Sharpness is almost at the seaside or Severnside to be more accurate . . .

....whose skip took part in the bow-hauling duties on one occasion! (Graham didn't bump us that time at least).


Fortunately that was the only occasion! And I guess that says something about the capacity of Alnwick's fresh water tank! Although I will admit to wheeling a fully loaded lavatory cassette in a wheelbarrow on another occasion - no purple paint marks on the wheelbarrow either . . .






Well not quite three months - we did a bit of boating (on a hire boat) around the Ionian Sea in between . . .

In Topic: Any narrow boats with electric motors?

Our next door neighbour has a true "Diesel/Battery Electric" powered boat - it is moored at Cropredy but has taken more than ten years of work so far and still suffers with occasional teething problems. Economy appears to be quite good because the diesel generator can run at its most economical speed but one area of difficulty has been failure of the thrust bearing on the electric traction motor - the motor was not designed to take the amount of variation in linear prop shaft thrust that occurs when a boat is constantly changing from forward to reverse as on lock flights. Running on batteries alone appears to consume far more power than was ever expected and the range of operation on battery power is therefore so small as to be impractical.
