Mr T.
Sutton, and I know it well, is but a stones throw from Hampton court, and Bushy park..where there is a really nice boating pond, with easy parking and a 20 second walk from car to jetty.
IF you were to bring this RTTL down on a Sunday morning (0915 to about 11 or 12 ish depending on just how sunny it is!) I am sure we could have a look at it and advise. It is not that tricky, this boat business, and there are many ways to simply overcome a bit of mis-alignment. I should be there this Sunday and could apply my vast bodging knowledge to the absolute full and have you wizzing around the pond in a jiffy.
Ashley PS I take it this is Sutton near ewell and Epsom and not sutton, yorkshire!! or somewhere
