Just wanted to add the following:
If you are tied to a fuel dock
you can't expect to be located in a place where boats who need fuel
would be blocked from getting to the pump. So I suspect that the LE was moved further and further down the dock while boats who needed access
came to use the fuel pump. I suspect that BMC placed your boat at the fuel dock because they were not accepting responsibility for your boat by placing it at the boatyard docks; and the boat was not "in their possession" since you did not provide a deposit that they had requested (despite any verbal agreement).
I would suspect another culprit in terms of the damage to the keel; since you mention that the boat was towed from HMB up to SF Bay in May you should also be aware that this time of year is whale migration season and that there is a huge probability that the boat ran over a whale and suffered damage to the keel. Last June we sailed from SF down to HMB and on the way back the whales were breaching all over the place. At one point I had the engine at full throttle (forget sailing) to avoid one coming up beneath my boat.
Again; I can't imagine enough lateral force or forces due to a boat resting on a shoal to cause keel damage. Many boats do this while up in delta sloughs while tied to the shore bow-in; or sailboats careening to do bottom work where there is no place to haul out. It really should not cause a failure of the keel fasteners unless there are severely corroded or fatigued bolts. I say this because the keel is pretty much the spine of a boat like yours; and if anything would have failed by sitting on a shoal it would have been a seam opening on the side of the boat due to the keel carrying the weight of the boat. The keel shoe is an integral part of the keel and it would have only stiffened the keel and protected it from any slight form of hard grounding if there was a rock beneath the bottom of the boat. How do you know it was sitting on the bottom? Was it sitting out of the water at low tide; and if so, how much and do you have pictures?
In this particular case I just can't find BMC to blame; as opposed to what happened to my friend waiting 6 months for rigging work and lots done wrong on other jobs, or the damages to the OP's Beneteau with subsequent "hostage situation".
If you care about the historic boat you own; and "never want to see a boat again." as you said in your pevious post; you should consider donating it to either the Maritime Museum in San Francisco; or to the Spaulding Wooden Boat Center in Sausalito ( Spaulding Wooden Boat Center: HOME PORT
).Be sure and tell them where they can find the keel (sitting on the Berkeley Marina Breakwater); so it can be retrieved and re-attached. Instead of being a floating planter box it would be restored, preserved, and sailed; and that's what I think Mr. Hess would have liked to see...
