Ron targets dysfunctional couples/families & works with them as therapy

In the movie Marty (Martin Short) finds out he inherited this yacht from his deceased uncle. Said yacht was previously owned by Clark Gable. He decides to go down to the island of Sainte Pomme de Terre, so he can sell it, also bringing his family along. Suffice to say, things aren't going well: Marty is having trouble at the office, his wife Katherine is stressed over her job as an architect/home remodeler (I didn't really catch what her actual profession was), their teen daughter just got engaged to a quite unsavory fellow and their son feels left out.Also add that when they do see the boat, it's kind of a piece of crap.
Enter Ron, a local captain hired by the broker guy, who helps them sail the boat to Miami with a few stops and complications along the way. Long story short, with Ron's guidance, Martin and his family learn to work together and decide to not go back to their previous lives, as well as keep the yacht they fixed up along the way.
Now at the end, we see another couple in a boat, and they seem not to get along until, lo and behold, Captain Ron shows up and starts doing his whole spiel like he did with the Harveys.
The theory: Ron mentions that he was a captain on the USS Saratoga, which was probably the CV-60) which has quite an extensive history. Now, extrapolating Kurt Russell's age to that of Ron (give or take a year or two) makes me believe that he could have been on the carrier when it was in Vietnam. Now I have no idea if he stayed on the Saratoga during the times she was stationed in the Gulf of Tonkin, but let us assume that Ron did go ashore, say on a patrol boat or sent in as relief. He probably saw some *beep* as what typically happens in Vietnam or any armed conflict, and it probably damaged him.
Ron finished his tour(s), attains rank of Captain (so it is believed) and he comes home only to be treated like *beep* because Vietnam war is bad. He most likely has PTSD, maybe lost his eye there too. So he decides to turn to the only thing he knows, the sea, in this case, The Carribbean. He probably hops islands getting work as a boat captain, which kind of enables self-medication through negative means (alcohol and women as briefly shown, this was sort-of a Disney film after all).
Now let's say before he meets the Harveys, Ron encounters another family or couple who need his boating services. Let's also say that they are in a similar situation as the Harveys. Being a Navy guy, Ron knows that all members/sailors need to work together in order to function, so he applies his (positive) experiences to help his clients solve their problems while he himself gets back the feeling of belonging to a crew again, which makes him happy. And when his clients are satisfied/together again, it makes Ron feel good that he made a difference in someone else's lives after going through the hell that was Vietnam.
