Easy to install, 10 minutes. Hardest part was cleaning out the garage to have 12' cleared, 7 hours :-). Screwed supplied bolts into rafters, clipped on the straps w/ provided carabineers, then loaded the boats into the straps Top boat was a bit awkward for a single person to load. A second set of hands makes it a whole lot easier.. Then figured to use and hold 5 gallon pail to hold the lower boat while I put the straps on. Made it a whole lot easier. Maybe if I try 2 pails I could get the top one loaded easier.. I will load a video of that if it's a tragic fail...... :-) I will post an update in a year let you know how it survives, good or Bad..
Great boat for experienced, intermediate or beginner. I liked the boat so much I bought a second one.. I have used on still to quick rivers, ocean inlets, bays and rivers. I even had it out in the open ocean (on a very calm day). Tracks very well without a rudder, Pleanty of cockpit room for supplies/ drybags and asoare paddle. Sealed compartment allows storage of small cooler and more supplies that need to stay dry.. seat is pretty comfortable for 3-4 hour adventures, longer than that I have additional pad that helps extend time on the water without your butt going numb.. :-) Only 4 stars because I would like to have seen more accessories specific to the Manatee (or Perception) models..
