Ive had this on my server for a couple of weeks now, and people legit love it. The vikingships arent used as much, but the rafts are literally everywhere. Colon is great for support, and seems to be constantly adding features and fixes as required.
Both Rafts and Viking Boats are highly recommended to open up new, fun aspects for any server. Colon has always been a great plugin dev and someone really putting out server changing plugins. A+ as always!
