Maybe renovation is a bit too big for this. The Red Ranger has two long, fixed portlights that let in a lot of sun. And heat.
In the summer, these need to be covered to keep the interior livable. It's that or air conditioning.
And we ripped the AC out because it was only usable at a dock. For the last two years, we spent minimal time at a dock.
Now that we're at a dock more-or-less full time. AC might be nice. But "nice" also includes "expensive". The power isn't free and the machinery must be maintained and it's storage that's lost to us.
Here's the old covers with a weird fastening that I devised.
This is what CA did using snaps and a single piece of fabric.
Shady in the summer when we need shade.
A little late this year, since summer's almost over. But it's ready for next summer.
