In 2003, Holt runs for harbormaster. He is opposed to the law that bans fishermen from coming near the orca that has showed up in the channel, as it prevents them from catching good fish and forces them to waste time and fuel by going the long way around.
When Nancy asks to borrow his GPS, he first makes her take a seamanship quiz. He wants to make everyone take the quiz when he becomes harbormaster, and Nancy is the test's guinea pig.
Though he refuses to take Nancy out in his boat to search for Katie Firestone at the end of the game, he eventually ends up rescuing her.
- A Holt Scotto campaign pin can be found under the water when exploring on the boat in Ransom of the Seven Ships.
- "Vote for Holt. Spread the word."
- "Those signs say no trespassing. Which means keep out. Which means you, girlie!"
- "Right as rain!"
- "Watch out for Caddy!"
