I disagree. The Spiegel Grove has mooring buoys and it is great to tie up and drop down with lines already on the ship. The less I have to worry about my boat in the hands of someone else, the better.
I would prefer mooring buoys to people dropping anchor on the site.
I have this console with the same SPG. Not exactly what you are looking for but putting it out there. It does have the compass port in the back. Would need to only recoup enough $ from it to buy a brass and glass.
