This is an interesting thread, and I'm glad that it seems to have been solved diplomatically. I have the same problem where my new-to-me boat is berthed in La Paz, Mexico; Double boat berths, with about 3' between our beams. My problem is that I am new to the whole trawler thing, being a sailor newly converted. I do have twin screws, which should help, and I bought two new large fenders for the outside of my boat for docking. I am going to the boat this week and will venture out and in to the dock for the first time. I will post if things go sideways,
but I am trying not to stress about it now.
Cheers, Bill
