Spider Webs in Boat

Okay this is a little off topics but was wondering if anyone had any secrets or deals with this issue.

Our boat is located in Central Texas area (New Braunfels) We get to the boat probably once every 2 weeks maybe a little more often than that. We always cover the boat if we're going to be gone more than 3-4 days.

Now the issue is damn spider webs, I mean these spiders are working over time, they'll rebuild webs over night and when we get back in the boat in the morning the first thing we do is have to knock down all the spider webs. Any secrets to keeping these suckers out of the boat?
