The Village Canvas custom made boat cover for my 16' fishing boat was purchased and made for me in 1993, and it is still very very much in use. Every other summer, I spread it out on the lawn and spray it down with a 15-dollar gallon of silicone waterproofing from Wal-Mart, and believe it or not, it is still in usable shape even after twenty years out in the sun, protecting the little boat from sun, rain, leaves debris, and snow.
It cost about $625 back in 1993, and if I had the money, I should probably get it replaced as it has a couple holes and is getting a little dog-eared, but it still gets the job of protecting the boat done.
Twenty years, actually 21-years now divided by $625 works out to 29.77/year .... and the boat underneath is protected.... or 9-cents /day ..... at 9-cents/day.....that's my type of a price! ,,,,
If you go to the huge Wal-Mart in Tilton, you can chose from about three or four different, off-the shelf, boat covers for 14-16-18' vee hull boats that cost about 50 to 100-dollars which are good enough if they fit your boat, but for the real-deal ..... a custom-made cover will hit the spot a lot better.....plus your neighbors .... will probably appreciate not having to look at a cheapie boat cover .....as well.
