Both ships are black because in their day, ships were made waterproof by coating them with pine tar. And both are terribly small for traveling over the ocean! It was hard to believe twenty-four men traveled on the Pinta and twenty men on the Nina. It was hard to believe Christopher Columbus had the gumption to set sail in them, even if the Santa Maria was larger! (They don't have a replica of the original flagship. Reasons given were that its hull would be too deep to get into ports they travel to and also it was lost before Columbus got back to Europe.)
Here's a picture of the Pinta from the side:
And here she is from the back (looking at her from the Nina):
And moored right behind her was the smaller Nina. This is a front view:
Here's a photo of her front lines:
And here are a couple of her crew members:
If you get a chance to see them, you should go!
