The top of my sliding hatch has been damaged by weather and the lack of varnish... It's working, but I think I'd like to go back to a plank style of hatch to mimic the seahood. You can only "restore" damaged wood so much.

But it is working, so it is likely to be near the bottom of "the list" for a while.

I like what Greg did on Guenevere for a spray hood and extra storage... http://www.svguenevere.com/prep/proj/spray/
