Sounds like a sub-optimal situation for the owner.
Photo shows what appears to be a front end loader swamped in the surf. Can only assume the owner was trying to dig a channel out for the yacht. I wouldn't be surprised if the damage to a digger like that costs more than what the boat did.
Bout looks in OK condition, but assuming its got sea water through it now, the engine, batteries and electrics wont be so flash.
Sad for the owner.At least he is trying to clear his boat off the beach.
