Nice set up, Bob. Thanks.
Well, an interesting Post Script to this story; I employed a mooring contractor who has scuba divers to retrieve the line. Rough quote: $200. I wasn't well and needed it done so went ahead. Invoice: $275.
When I inspected the main riser line I found it had been twisted until it had multiple deformations. Strangely, the clear tubing had disappeared and the eye splice had been redone in a somewhat bodgy manner:
The contractor who retrieved it stated that they didn't modify it at all. Huh? So the only thing I can surmise is that someone has run over it and got it caught in their prop and twisted it and mutilated the eye splice and tubing. Then they've tried to rectify it by re-splicing the line then either dropped it overboard unattached to the buoy or dropped it over connected to the buoy by a few strands which subsequently broke. Despite their efforts to rectify it, they failed and cost me money. They had my mooring number so they could have got in touch and done the right thing.
So then I'm left with a rope that needs rectifying and a report from the mooring contractor (whom I had not used before) stating I need the chain replaced with photos of chain worn through to about 25%. That's weird because I'd had the mooring lifted and dropped by my usual contract only 6 weeks prior. The whole thing was just getting weirder and weirder.
So i call my usual contractor and explain the situation and forward the photos. He says he'll have a look asap. Next day he lifts it and finds that the worn chain is ground chain for weight only - there is another length of chain for strength beginning and terminating at the same places so, no, the chain does not need replacing. So he replaces the length of rope and splices it and tells me that because of all the stuffing around I've had that he will not be charging me at all. How many times in the marine industry have you heard the phrase, "No charge"???
I cannot tell you how difficult and confusing it was dealing with the other company; conflicting messages depending on who you spoke to and I'm sure I would have been up for another $500 or so by the time they'd serviced the mooring unnecessarily. I should have called my usual guys straight away despite the fact they don't have a scuba service - they could probably have retrieved it anyway.
