Teenagers made fast friendships during a week long sail on the Denis Sullivan. (Laura Johnston, RocktheLake)

The teenagers marveled about the brightness of the stars, and the strength of the friendships they made. They also complained about the mayflies.

Such is life aboard the tall ship Denis Sullivan, as part of the Rotary Club of Cleveland’s Project YESS. Nineteen Cleveland teenagers sailed from Milwaukee aboard the ship, which returned Tuesday to Cleveland before heading to Toronto.

Denis Sullivan, a recreated commercial sailing vessel, will be back in Cleveland July 11-14 for Tall Ships Cleveland.
