1.   The yachts bobbed around on the choppy sea.

2.   The sandal evoked romance, dancing under a canopy of stars, yachts bobbing in the harbor.

3.   Yachts bob in the boat basin, and flocks of cawing seagulls circle fishing boats unloading their catches.

4.   Workers on the upper stories can see the yachts bobbing below them in the marina, and Mount Sannine glinting under its cover of snow.
