Getting a stretch
QWe are thinking about having our 41ft steel narrowboat extended by 10ft or so. Do you have any thoughts on the advisability and any potential problems? The hull is specified at 8 / 6 / 4 and around 5-7 years old. The engine is a Perkins 100 series 1500cc with a small PRM 100 gearbox. The work would involve extensions to water pipes and electrics but no major mechanical alterations. PHIL DEACON, via email
AI am running a 1498cc engine on 55ft and I am happy doing the Thames tideway, so I think the mechanicals will be fine. If the gearbox is okay now, then it should still be okay. If your wiring size is marginal and you have any heavy current devices (or a fridge in front of the stretch) they might suffer from volt-drop, but again I expect they will still work. Question the boatyard to find out how they will ensure you do not end up with a banana-shaped boat.
