While Kate helped hoist the sail, the Prince continued to work on the rigging, and cheered after the sails were finally hoisted.
He added: "We all need to be a lot more open about all this stuff. The more we're talking about mental health, the more we're finding there are so many more services needed for people who are struggling."
While on the ship, the pair also enjoyed a chuckle with bosun Steve Atkinson about his full beard, with the Prince saying: "That is the most amazing specimen I have ever seen. Seriously that is incredible, it must have taken you ages but you must be very proud. I'm very jealous"
Kate joined in on the fun
The royal pair chatted to the young people about mental health during their visit, and listened to their personal stories. Prince William said: "So many people's natural reaction is to close down, talking things through is crucial…we're very glad you're still here. You're very brave and you should be very proud that you've shared your story."

The 25-year-old said of the meeting: "Kate told me I was competing with her brother. I told William it took me nine months to grow."
The Duchess changed from her earlier chic Zara and H&M ensemble to a suitable sailing outfit, donning a casual khaki Troy jacket, black leggings and white Superga pumps.
The couple are enjoying their final day in Canada, and Kate spent time chatting about her son Prince George at the Cridge Centre. 20-year-old Zara Auld from Victoria said: "Kate asked me what I like to do and I told her cooking. She asked me what and I said Italian like pizza and pasta and she said George loves that."
