Most trailer yachts are less than 25 feet long. They are small and the mast is not too heavy for one man to handle. Many older yachties stop sailing because they can no longer handle the heavy mast. Those with money, can easily move on to a larger keeler, 28 to 50 foot. They can continue sailing until the money runs out. The plus points are many: Drive to the marina, park the Mercedes, walk aboard, start engine and cast off all within 15 minutes. The mast and sometimes even the sails are permanently installed, using furlers!
To continue sailing, a compromise solution is to berth larger boats at a marina (boat parking). The mast is left permanently up with the main lowered or furled. The jib can also have a furler. No more hard work towing, rigging up, launching, recovering and rigging down the mast any more. The boat remains afloat always and the mast and other gears stay permanently rigged. The blue cloth is for protecting the sail against UV. The owner drives leisurely in his saloon (no more 4x4) to the marina, starts the motor and cast off; all within 5 minutes. Once clear of other boats, he removes sail covers, raise or unfurl sails, pull on the main sheet, cut the motor and away he goes, just like before; but all within 15 minutes!
