I've been carrying a Victorinox Swiss Champion -- I bought it in Brugge on a touring trip through the Zermatt/Matterhorn area -- on my belt for about 35 years. And I can use that, along with a Leatherman tool, for maybe 90% of boat fix-it chores.
I agree it's a great tool and a good recommendation for other work... but I think it's not what OP is after here. Opening one-handed is not gonna happen. It's also too bulky to be a true "pocket" knife. And the main blade doesn't really "lock" into the open position.
FWIW, the other knife I carry all the time is a Benchmade pocket "flick" knife, which means it's mostly a "one-handed" piece. When we're fishing, the mate carries a Kershaw spring-assisted pocket knife. We keep a Buck folder onboard, for various chores, but it's not a "one-handed" model. My onboard emergency belt knife is a SOG "Pentagon" model, a 5" fixed blade with straight edge on one side and serrated on the other. Their shorter model might be less cumbersome when wearing it...
