John,
On La Reina I changed out the plastic clamshell vents for stainless steel. They cost about the same and weighed about the same. The edges are sharp and can bit your ankles but they are nice and bright. I have attached a photo. There are vent in the photo is for the engine air intake. There are two matching covers on the port side for the bilge fan exhaust and the Espar heater air intake.
For more information then you wanted: In addition to the vent covers you can see the Murray Cressman boom extension. It is hard to see in the photos but I have also added the Murray Cressman 3 eye bails for the reef lines and topping lift. Mike Quill sells a similar product that looks very nice. I have changed the blocks to Garhauer. The standing block for the main sheet has been moved off the coaming down to the rear deck and turns at the stern chock. I had to add a wooden pad under the mainsheet whinch to make the sheet run properly and not rub on the eyebrow. The shore power is a Smart Plug and the dorade air intake has also been changed to a nice stainless steel scope. It weighs more and cost more then the plastic one it replaced. The fender covers are the legs from a pair of fleece jogging pants. Keeping with the cat theme, the symbol on the covers is a Puma. Oh yes, you can also see the dodger and enclosure with the nice stainless grab bars. I came up with the initial design of the enclosure and then worked closely with the canvas maker to come up with the final design. I took him out sailing on two occasions so he could see how the mainsheet ran. Overall I am happy with the final product but would make a couple of changes if I had to do it again. That is my bragging for the day.
