Kamikaze,
I also have a Sailrite LSZ machine. It's a beast going through multiply layers. I'm probably going to be stepping up to a full industrial machine soon. Maybe a Sailrite 111. I keep getting more and more inquiries regarding repairs etc. I actually enjoy doing the work however it's time consuming to make things look good.
I think a dark navy blue would look great for your enclosure.Off set the blue with white binding and white zippers! If you decide to do a white or off white you might consider a vinyl material like Stamoid. It would make cleaning it so much easier. I would imagine a Sunbrella in a light color would be very tough to keep clean esp if you like to fish. I just did a top for my V with a tan/beige. I used black zippers and binding. I really like the way it came out.
Got fancy and made zipper blind to keep out water spray.
Used this old binding I had laying around for the edges.
We use Naxa tv's on our Bertram. They are 12 volt with built in DVD players. The reception is pretty good with one of those paper thin stick on antenna's.
We've had good luck with them. I would imagine you could use a foldable mount that would secure it to the hardtop out of the way when running.
