ENOUGH HORSE POWER?
QI have seen a 40ft Liverpool Boat narrowboat for sale at £26,000, which seems fine but I have one concern: the Yanmar two-cylinderl diesel engine develops 14hp and I wonder if it is underpowered. I do not intend to cruise tidal rivers. TG, via the CB website
ATONY REPLIES: In today’s terms I think you are correct, but remember Liverpool are/were a budget builder. It is also worth remembering that in days gone by, full-length cargo-carrying boats had engines with this sort of quoted horsepower, or in some cases less (albeit they swung large props, which tend to be more efficient than smaller ones). I suspect it will be fine on canals but I would not be so happy on a river with a bit of flow on it, and it may take a fair while to stop. It is also important that the propeller is properly matched to the boat and gearbox reduction.
