"We did have a problem with the starboard holding tank being clogged"

Next time if this happens call Moorings service and they will send a contractor out with a compressed air tank and he will go underneath and blow the s*** out. This has happened to us 4-5 times especially when the boats have sat for a while (e.g. post hurricane or Oct after base was closed). They have come to Norman, Peter, Virgin Gorda Yacht Harbor

We had one curious sole who wanted to watch for some reason in the water and was surprised when the contractor went flying by him in the water back to the boat followed by a large "cloud".

I can also tell you opening the pump out and using a "plunger" doesnt work either...but is really funny to watch
