I did bring my hiking shoes and did use them on the times we were at an actual dock. For the wet landings, you need there waterproof tall boots, but there aren't that many. Last time we went, I brought my hot pink muck boots, which were new at the time, but they have been out to the ranch a lot since then. And I don't want to pack them in a suitcase, no matter how clean I try to get them, so I will use the ship's boots. George will too--hope they have a size 13.
I would say on the previous trip, it was 50/50 as far as dry vs wet landings. IMO you do need to bring hiking shoes or boots.
