This is my first season in the Maximus Centurion, and it is not bad. Prior to it I was wearing an Astral 300R which I still think is one of the best vests ever, but, it was getting a bit old, so I started looking for a new vest. I am 6'2", 225 on a good day, 34 inch inseam. I took the L/XL and it fits well for summer boating (over a shorty splash top) and winter (drysuit with a ton of layers)
The Centurion is extremely comfortable, and feels a bit more flexible then the Astral. It is really well thought out, and holds everything I need well. I switched from a fixed benchmade SH20 to a folding Spyderco rescue, and I like how tidy and away the knife is, but still deployable quite quickly. The vest is "long" and could be an issue in a highback seat depending on your torso length. With low back seats no problem, cheetah chair in a ducky, a little uncomfortable, but I could always try to get the vest to ride higher too.
I usually keep a pair of locking biners, 2 prussiks, GU, sunblock stick in the pockets, and sometimes I will add a bit more stuff, (beanie in cold weather) PLB while sea Kayaking, and it holds everything quite well.
While rowing (culebra or superpuma) I have not had any problems with oars catching on the front of the vest.
The QR belt is well thought out, with a clean path to the vest. I do feel like it takes a bit longer to get it on, secure it and get on the water than the 300R, but 20 times out, and I still like it.
I think it is a pretty solid rescue option for rowing
