The jib is rigged in the opening shot, the line runs from the jib to the bullseye, through the coaming and to the cam cleat on the CB trunk. It's much clearer in the movie. They did shoot some actual sailing on the water, and others are studio green screen shots. Somebody in continuity messed up!
Here's another shot showing a couple more boats that look like DS's, but it's a bit hard to tell the insignias. It looks like they are DS's but they've rigged them with different sails. The dude with the slick captain's hat calls the DS a "Spatterbox". And he says it's got too much weatherhelm. Funny.
Oh yeah, no PFDs!
