I bent a set of stanchions doing that.

Re: Low buck projects- Let's see 'em!

When I did it I didn't have to bend the pvc tubing that much. There was very little bending force on my stanchions. Survived two winters without a problem. Also the tarp is not stressed this way, not like a tarp that is stretched by itself over the boom.

Re: Low buck projects- Let's see 'em!

This PVC frame I did build for sailing purpose, but not for covering the boat. I just adapted it for covering a boat for you all. I really don't advocate covering boats, but if you have to cover, it should be an easy good design, so I though I would share. I can not find the pictures of when I had it set up, 60' long, in my back yard, to recondition my mast. Winter project. I now use some of the frames to hole netting up over the coy pond.

To attach the frame I would lash to the outside of the stanchion base only, or if you have a toe rail that has holes in it, and on the outside of life line. Stanchions and life line will be inside the cover and should clear the life line and not touch them. Tarp should be tight enough so no snow or water can not accumulate on top. And when you attach the beam rope tighten it down to squat the frame bending the frame to bow it around. This will give it spring and hold it tight and will not allow for much side to side movement. If you make the top two PVC pipe longer to make the frame wide enough to clear the life line and stanchions, then bend them in (this will work fine too), you will need to add gusset ropes inside from the side 45 deg elbows across to the base of the frame to keep cover from swaying. Tying off to the mast will eliminate most swaying and or planing to use the boom just under the frame will work too.

If you would like me to show these options in plan form, I will be happy to do so.

Think spring!
Eric

Re: Low buck projects- Let's see 'em!

I made a similiar frame from pvc years ago and its still going strong. If it will help, several points that have worked well on my frame...I drilled 2 holes in pvc center ridge about every three feet
for 3/4" ribs which pass though center ridge and connected 2 pieces of the 3/4"
rib material as needed then cut to desired size , they fit into holes in pvc that run along
(inside) port and starboard toe rails.(ribs and all numbered) This creates tension that works well and can be carried all the way back to the stern. Another big help is using plastic ties to hold things in place when setting up and from wind, come spring they cut off real easy.
Pretty strong, stands up to wind and snow.
Hope this helps.... Hugo

Above post was from prev. thread.... but the pictures just wouldn't travel with copied text. If any interest in pictures they are on thread titled...
"I just don't get it. Winter storage " 2/16/2011 post # 31....frame is really a thing of beauty.
Sorry but when it comes to sailnet and pictures "I just don't get it!"

Re: Low buck projects- Let's see 'em!

The problem with any flat top, is snow is going to accumulate. There is no need for structural ridge beam. If you think that will hold snow or any cover can, good luck with that.

And keep in mind this is a low buck project...under $100. 5 or 6 frames of my design (for a 32' boat) and about $10 each frame and 3 3/8"x100' rope from Walmart for $5 each. Project is frame only, no tarp cost. Project is not how to cover, but how to build a cheap frame that will hold up.

Re: Low buck projects- Let's see 'em!

Looking at these frame designs I cannot see how/if the tarp is attached to the frame at any point.Can someone enlighten me on this subject please.In New Zealand we do not have a snow problem per sec,my interest lies in building a frame to cover a boat when out of the water for major refurbish.-Thanks-Chris

Question Re: Low buck projects- Let's see 'em!

When I did this the tarp wasn't attached to the frame. It was attached to the toerail with cord and/or bungees, just using the frame for support. That is the advantage of this as there is less strain on the tarp. When the tarp is just over the boom as many do it has to be tight and wears out a lot faster.

.. and when the sail and cover are left on, just as hard on the sailcover too!
