just saying those drains for the cleanout tray have me jelly beyond belief. One of the things the 19' boats have going for them.
Someone on here did their boat name on the side. Given the overwhelming number that have it on the back, it trips up the eye when it's on the side of the boat, IMO. I can't recall who did it, or where to look, but if you do a simple google search for boat transoms, you'll see what I'm talking about as far as the sheer number of names on the back, and not the sides.
I don't know if you find that second hand strap useful, someone else could chime in, but if you're so inclined, that could be removed, the holes could be filled/patched, sanded and polished, and you'd have more space. You could also replace the fabric strap with a metal one, or move the OEM strap up a bit, or both (metal grab bar AND move it up).
Alternatively, you could find a smaller font, or stretch the font you choose, to have it fit the area slightly under the handle, so it would be centered, if that would be your concern. My boat name has been italicized and stretched to fit under the handle as well, if you're looking for an example of what I'm referring to.
Plenty of ways to skin that cat, the deciding factor is what you think would look best, and the effort you want to put into it. Make it hap'n Cap'n!
