Full tower cover

Hi there,
My boat is in a place where there is lots of birds, insects, and potential thefts...
I recently found this full tower cover, and the guy actually folded it out and back very quickly.
I know it doesn't look so good, but It protects the boat, the tower and all its accessories from dirt, rain and sight...
It includes a near the top ventilation grill, so it has a minimum of moisture.
I had a quote for a taylor made but it is quite expensive,
I was wondering if something like this exist readymade for a 2002 Air Nautique?

I had a cover like that made for my old boat, it was cheaper than a garage or carport. Mine covered the platform and had a velcro flap that made a door in the side so I could get in and out without removing it. To put it on I had some velcro loops that attached to the tower and then you just walked around a pulled the sided down, a little more thinking would have to go into it if you want to cover it in the water. I loved it and will probably build another.

Now for the bad part, for my 18ft Centurion it took over $600 worth of Sumbrella to cover it and the cover was a little over $1000 total. I had my upholstery guy do it.   He likes these challenging things I come up with, and made it so tight that I could have towed it in town without any excessive flapping.

Ryan's 'fake snake' isn't a bad idea, if something is just on the tower then some sort of strip that would keep them from landing there might help.
