Re: Backing up (or not)
Smack, I had a Maxprop on my last boat, a Niagara 35 with longish fin keel and big spade rudder. In general there was very little prop walk but I learned that if you wanted some, eg to pull the stern into a dock you could goose it in reverse for just a second or two and you would get a quick jump in the desired direction - you did choose the dock to allow this of course?
Heading back to Lake Ontario for this summer. Ainia is back in North America for the first time since 2010. Currently in Long Island Sound.
