Catigale I've got to admit this shelter was North of what I feel is cheap($$$ wise, still cheap sturdy wise).
Rebar was $5.90/10ft so $41.30
PVC sched 40 3/4" pipe 21 pcs @ $5.69(Home Depot) $119.49
7 pcs 1/2" pipe(already had them) $3.89(Home Depot) $27.23
2 100' coils 1/4" line (cheap H.D.) $9.99 $19.98
Tarp (bought last year, guessing a bit here) $69.99
Used Cinder blocks could be gallon jugs with water. FREE
Total $277.99
At 30' I'm a bit snug front and back, I'll probably put the tongue of the trailer out so I have more room around the motor and masthead. I could've used another 8 pcs of 1/2" to make two more full runs end to end to take up play; this would make 5 runs end to end like the ridge line I'm tying in the pic. We drilled holes in the 1/2" and ran string through but no holes in the hoops. My ridge pipes are bent because they're my hoops from last year, straight new pieces would've tidied things up alot.
Mistakes: I tied ropes diagonally before tying on 1/2"pcs for stability, this threw off the centers/spacing and put some odd bends in every thing. Also pounded rebar with deckhands eyeing the line on the Port side, this threw the hoops out of line quite a bit.(starboard was laid out along a string, much straighter). 3sections together bend easily, could've used 1"($7.99ea at HD) for a more rigid structure.
My main idea is that the pvc is "noodley" and if I get alot of snow or wind it'll just bend all over but hopefully not break. The car shelters and temporary garages popular through Costco etc are either not long enough or not tall enough or very expensive $600+. My frame is roughly $200(could be shopped better). My father in-law had one of the 20x10 car shelters and of course we got snow that year and all the metal pipes were ruined.
With the amount of land I have I probably would've been better off buying lumber and building a greenhouse style shed. 3pcs of 10ftPVC makes a 30ft hoop, 4 8ft 2x4's cut at 30degrees makes a 32ft hoop. I could play with the angles to get a shape that clears the mast. I'll need more lumber 2x4 and 1x4 but the pieces are usually under $2 each, so per hoop I'm $8 instead of $17. 15pcs of 1/2" to hold spacing $58 vs 24 1x4s for $36. By the time I'm braced diagonally I'll still be the same $ or less for a much sturdier structure, however it'd probably fail in a bad way if we get a pile of wet snow(its the Pacific NW after all).
As with all of these projects, I'll probably spend double the next person who sees mine and makes some obvious improvements while avoiding some of my sillier mistakes. A 40x30 tarp would probably be ideal, closing it right in but airy enough not to rot the boat.
There's alot of room under there! And I can pull the trailer out leaving the boat on blocks(trailer needs tires etc, centerboard is choked up with eel grass!). It does make me feel alot more like modding when I can move about the deck.
