My 2010 Getaway has spent every day of it's life outside on a Lake Michigan (Illinois) Beach. A snorkle for the jib in summer, and the mast down and inside in winter is the limit of what I've done - haven't even bothered to take off the trampolines. 4th summer so far and I haven't even had to tighten the trampolines much yet (and no tears or significant sagging after a few heavy winter snows - maybe down 2 inches or so from new from regular use [with the front more worn than the main]). I intended to take the trampolines off and maybe store the boat, but I live a bit away from the beach and never made it the first year. Having seen no significant damage in year two, I figured replacing the trampolines every 5-7 years was still cheaper than a trailer and cover (the dealer dropped it on the beach for me when I bought it). We are protected by trees, but far enough away not to worry about sap or leaves, and with the current wear, I think 7 years is easily possible.
These are tough, well built boats. FWIW - of about 150 Hobies on this beach in Wilmette, IL, nearly 100 stay out all winter (though many further from the tree line do take off the trampolines due to wind worries [we have deep anchors in my row and are protected by trees and small dunes]).
Mast up during the year presents no problems - all the 150 Hobies are stored that way during the summer (and a few don't even take their masts down in winter). My stays have spent about 20 months outdoors (and in fresh water) and look fine. I think I will replace them at about 6 years (6 summers of 5-6 months each outdoors = about 3 years full-time use) just to be safe.
Everything on the Getaway seems to be plastic, aluminum or stainless, so a short wash with a hose and mitt at the start of the summer is all it takes to get it looking great. Anything perishable or likely to be fouled by sand - rudders, lines, blocks - is taken in during winter as well. All this plus a couple of well-considered quick releases for the tiller extension and main block, and the boat can be ready to push to the water in less than 5 minutes (mainsail, mainsheet block and lines, etc. stored in bin on the beach).
