Windows III

I've been doing a little too much business travel for a lot of boat time.  My lack of progress has of course make more window options to appear.  A set of windows that look promising appeared in the local kijiji ad.  They are unused.  Here is a rather poor rendering.  The good news is the installation would likely save time and weight.  They don't come with screens or the ability to lock the window from the inside. Even at half price they aren't cheap.  I'm not sure I like the look.

Ports that open have some obvious advantages  provided they are light and sturdy.
