I just thought that I would add this artrist’s rendering of Yorktown in her final resting spot. The “gap” is visible at the top of the island structure.
A tip on the wooden deck. Use a good hardware store type spray sealer, like Krylon, to seal both sides and all edges of the wooden deck. If you want to stain the deck you can use a thinned-down version of the an enamel paint before sealing, or paint it after sealing. A water-based acrylic will cause the thin wood to warp. Even humidity in the air may cause warping. Sealing the wood with a solvent-based material reduces the chances of warping
The deck came with a disclaimer not to use acrylic paint. I was going to use enamel due to this, at least on the deck. Do you still recommend using a sealer?
If you use enamels make sure to do both sides. You need to seal it one way or another.
