Scott went on to share another adorable photo of Penelope as she stood on a wooden set of steps during a boat trip.
“Poosh,” he captioned the image, using a nickname both he and Kourtney, 39, have used many times in the past.
“Just sailing,” he captioned another image showing himself relaxing on the trip while North stood at the edge of the frame.
Although the exes, who ended their nine-year relationship in July 2015, did not pose for any photos together, the mother of three also extensively documented the trip — and one of the photos was even taken by her eldest son!

In her latest snap from Bali, taken by son Mason Disick, 8, Kourtney leaned against a wall while wearing a yellow-on-yellow outfit.
“By Mason,” she wrote alongside the image, making sure to give him ample credit.
Giving all of her children some love, Kourtney also posted a series of adorable images of her and her daughter Penelope taking in the local scenery.
“Thank you Bali for the happiness and peace,” she wrote alongside the photos.
“He protects her,” Kourtney captioned the photo.
While Kourtney and Scott have had their differences over the years, the exes are in a good place right now.
“Kourtney and Scott are friends and co-parents. They have a very good relationship, so it’s not strange that they are together with the kids,” a source recently told PEOPLE. “They want the kids to feel like they are still a family and can have fun together.”
“Lately, Kourtney is very happy with Scott,” the insider added. “He is taking care of himself, isn’t partying and is a great dad.”
However, just because they’re getting along doesn’t mean they’re likely to reconcile, with a source telling PEOPLE this summer that Kourtney “will never get back with Scott.”
“She’s happy that he’s doing well and spending a lot of time with the kids,” said the insider. “She’s happy about co-parenting with Scott, but that’s it.”
Scott has been dating 20-year-old model Sofia Richie for about a year, while Kourtney, 39, previously dated Younes Bendjima and has stepped out numerous times recently with model and actor Luka Sabbat, 20.
