From the pics, it looks like the top is the same contour as the original bow.
Pretty sure I would want (and need ) a flat surface.

LL, you could open your own "Jimmy Buffetts" with that. Every table in that place is a boat.

I like it! I could put it just off to the left of the spa, move that blue flowering plant right before the stair way to the patio

Nu2, if that's the "blue flowering plant" that I am thinking of; it'll get way to big for the location that it is in anyhow.

And, um, there's a sand shark in your spa!
