Too hot to sail...
My current boat is the first one I have had with a Bimini and I have to say it makes the difference between going out for and sail or not. The canvas was in bad shape so I removed it and used 6' x 7' silver tarp from Mcmaster Carr for $10. It hung down on both sides a bit and provided even more shade than the canvas. A second one over the boom keeps the sun off the cabin. I can then leave the sliding hatch open when the thunder storms roll thru. A 4' square one does the same for the open forward hatch.
