Not sure which the most appropriate sub forum to ask is, but this one looks good.
My home sailing club (www.gravesendsc.co.uk
) have been fundraising hard to build an accessible landing stage off the front of the clubhouse - Gravesend is obviously fairly tidal, and they currently access the water via a vertical concrete wall, with dinghies being launched by crane!
They were originally getting some Ex MOD pontoons, but for whatever reason this seems to have stalled.
If anybody knows of some secondhand pontoons floating about (!) available, ideally steel/concrete construction, please drop me a PM or e-mail me as below, and I'll send on to Dad (who is project co-ordinating). the sort of size they are looking at is two lots of 10m by 2m or similar.
The company they are using for installation has the walkway etc, but all relevant pontoons etc are open to negotiation. Because it's a fairly exposed location, the slightly lighter pontoons normally found in sheltered marinas will probably not be man enough for the job, so they're looking for something a bit more industrial. Ideally secondhand due to financial constraints!
