I did not use patterns to lay out the bimini /enclosure. The bimini I purchased from a local canvas shop. It cost about $500.00 with the stainless steel tubing and is about the same size Kilburn Adams suggested. The dodger and side panels I made after installing the bimini on the boat. The material is Sumbrella Canvas material. It took
12 yards of canvas and 8 yards of window material.
Clear Vinyl, 54" Wide, 30 ga $15.00 yard
Natural (White), 60" Price: $20.99 yard
This did turn out to take a lot of time. I made mistakes which added about 25 percent more canvas than needed.
I did save about 40 percent of the cost, but I never want to see a sewing machine again. You will need a heavy duty sewing machine that can push a needle thru 4 layers of canvas. I found one at a marine swap meet and sold it when I finished for $25.00 less than I paid for it.
This is how I completed the canvas enclosure.
Mount and make sure your bimini will not move during the enclosure work.
I attached a zipper across the front edge of the bimini. Two zippers on each side and one zipper across the back. Then I attached a matching zipper to the dodger piece (3x8 foot) of sumbrella canvas and zipped them together. I doubled over all the edges before adding zippers to the panel. Next I pulled the canvas forward and arched it across the cabin deck to get about 45 degrees.
Pulled the side of the dodger down and over the side of the cabin and marked the lower edge for cutting. I left about two inches for folding over. Marked the window locations and the two zippers locations for the center window.
Cut and added zippers to center window. I cut the vinyl windows to the size I wanted. I got the vinyl window material at a canvas store. I attached the clear window material to the canvas before I cut out the canvas opening for the window. This will keep the canvas from wrinkling. I used a heat gun edge to cut canvas to prevent unlacing of the sumbrella material.
Added a strip of canvas about 4 inches wide across the cabin top
canvas to attach the dodger front edge. Mounted the mahogany wood piece
on each side of the cabin top for the dodger.
Add rear zipper to front side panels.
One mistake I will change soon is I made canvas window panels to cover the windows. I put the covers on the outside of the enclosure and dodger. This was a mistake. They are hard to get to and can blow and flap in the wind. This was from years of having boats with the window covers outside to protect the vinyl. What was I thinking, since I keep the boat in a garage and the main use for the covers is privacy.
