The first thing I thought of was pot and I don't even smoke pot.
I did a boat transom once in real gold leaf, by hand, named Mary Ann.
I kept it really simple and tasteful, just a basic roman font.
I wouldn't worry so much about colors as I would the busy look of your layout.
Your name font is nasty, not classy, and it looks distorted.
If the customer wants palm trees by all means give him one, not many.
Boat lettering should be elegant or even fun, but never tacky or busy.
Here's a 5 minute quickie idea.
Love....Jill
