OK, here is my build of the classic Revell kit. No photos exist of the actual boat so I did what I could. There are some descriptions in a few reports on what it looked like, along with info on how they painted the boats in the theater so I based things on that. . . .
So here is what I came up with. Ya, no big 109 on the hull, that was made up on the float they used in a parade for Kennedy, they did not actually put the big hull numbers on the real thing.
