I have noticed a lot of nameless DaySailers. I am of the opinion that every boat should have a name. Maybe you have one thought of, but don't feel up to painting it on yourself, or don't want to pay someone else to do it. I found this site a while back. They make custom vinyl decals and have ordered a name decal for my boat. We'll see how much I like it.

They have a ton of fonts, colors, and effects with an updating preview feature. If anything, it's fun to play around for a while.
