hi new on here (and new to canals)
i bought a 22.5 norman 4 berth boat (about a ton in wt) and without any outboard
on e bay at Northampton
The plan was simple move it to sheffield with a 24 volt electric outboard charging batteries at moorings
bad plan this was no good as the outboard doing about 1-2 mph kills 2 batteries in about 2 hours
and visitor moorings do not have power
the outboard was rated at 96 ft lbs push and i estimate = about 2hp
so a heavy boat will need a lot of batteries and a lot of charging
as the trip was grand union,oxford, coventry, trent and mersey, macclesfield, peak forest, ashton,
rochdale, calder and hebble, aire and calder, new junction and the sheffield and south yorkshire
you can see 1 to 2 mph was not going to work i bought a 5hp honda and did it in about 30 days
