Re: Bimini
You can purchase them new here on iboats, you can surf ebay or craiglist, or you can find a local marine upholstry shop who will likely have them as well. Measure the width or beam of your boat and then determine what length you want- do you want a short top which only covers the pilot and passenger, or a longer one which will provide shade (yes yes) to the rear passengers. Then, inspect the gunwale surface in order to determine exactly where you can mount the top so it can either fold down completely and lay flat or be supported at a 45 degree angle by bimini top braces. I made adjustable braces and then used quick release pins so I can either leave it at a 45 degree angle or drop it completely flat in order to put the boat cover on for storage. I'd go with extra long hardware that way you can always carry a hacksaw out on the water with you and lower the height as needed after you use it a few times. Initially I started with mine very high because I'm 6'4" so that I could walk around without bending over, however after a few trips out I realized that because the top was so high, too much sun came in from the sides and not enough shade was provided. After lowering it about 6", its perfect.
