A note on mounting pads; I have a single 1/2" bolt that threads up into each leg of the pulpit from below the deck instead of three or four smaller bolts with the heads exposed on deck. The mounting plate for each leg is 3" in diameter with a hole drilled in the middle-the nut is welded over this hole and then inserted into the tubing and the plate is then welded to the tubing. It looks clean and makes a smaller access hole in the salon overhead. ( I have used a similar method with stainless handrails only I found a threaded stud with a nylock nut easier to install. -js ). The pins are just 1/2" solid round stock welded through the cross bar. You will be amazed at how many uses you will find for the pins once they are there — I cleat off my lazy jacks, downwind pole topping lift, main halyard when not in use etc etc.
I recently went to look at a boat with a friend that was interested in buying a sailboat up in Kenosha, Wisconsin. This was the first time I had ever seen Granny Bars on a boat, and I thought wow, that’s a great idea! If you have ever been out and had the weather turn on you such that you needed to reef the main, you know how unstable you can feel up on deck in those situations. You are trying to hold on at the same time as reefing the main. Plus, if I have to single-hand, which I am sure I will, then in addition to jack lines for safety the Granny Bars would make me a lot more comfortable since there would be no one to fish me out of the water if I fell in.
