In my experience; Solo, with friends & a partner, as a skipper
of pro' racers, & also charter
boats. Both in the US, as well as "overseas". Quite honestly, it's much easier to eat healthier, if for no other reason than you can't/don't stop at the grocery store or for fast food on the way home, as you are at home
And or "stopping on the way home"/running to the store, entails; getting into the dinghy
, tying it up/beaching it somewhere, then going to the store/market/resturant... often on foot or via taxi, & then doing the reverse, prior to cleaning
your produce & cooking... From Scratch.
The From Scratch part being a BIG factor. As more than likely, you'll be using much fresher ingredients, as well as a much healthier balance of them in every meal. Even if it's as simple as making whole grain cereal or oatmeal for breakfast. Which is a big switch from sugar coated, triple-sugar puffs from the store. And after a bit, it's easy to wean folks off of much sugar at breakfast, even if it's just a switch to honey or molasses. Including in your Tea & Coffee.
And everyone not only gets a say in meal planning, but also in cooking
& cleanup. Not to mention that meals
are Definitely more of the type where everyone sits down together to eat. So it's more of the traditional family/crew type of event. Much as is everything involved with meals
onboard. And with that, because of folks (kids especially) food preferences, you can entice the finicky ones to have more of a hand in every part of the meal process.
Even my Uber-Finicky little brother, when he was 5-11, would cook once or twice every 2-3 days. On a sked. Maybe only half of the meal sometimes, but that was for all 4-6 of us. And he would really Eat (onboard). Where as at home, it was a chore to get him to finish half of a sandwich.
And he definitely did got into the grocery shopping
thing as well as cleaning
up afterwards too. So it was a BIG swtich. One which my folks were really glad to see. As often he & I would do whole meals from start to finish, including dishes. Though often the chef(s) got a pass on such chores, as part of proceedure. Both onboard & at home.
This went on from when he was 5 & I was 7, on through adulthood. And was something that we loved when onboard or when camping. And it grew into a habit at home later on from there.
The whole family being involved in every aspect of meals includes shopping
at farmer's markets. Gathering food from the sea. Be it fish
, shell fish
, kelp & other veggies, etc. And then there's the fact that the fridge & freezers onboard boats are much smaller. So you shop for more fresh stuff more often, ergo healthier meals. In addition to doing things like sprouting, storing quality produce as our ancestors did a century ago, in modified "root cellars" onboard. Etc., etc.
It's what you make of it, but it's easier to eat healthier, kind of out of logistical necessity. That & outside of the US, in non 1st World locales, IMO the food's healthier even when you eat out.
Plus who else is better at making friends, & finding unique resources than kids
? Could you get them to eat goat's milk cheese at home? They'll likely find it if it's avaiable when you make port, & bring some home. Um, baby chicks too
Also, via living onboard, there's much less of the vidoe game
culture. And a lot more chances for kids
& adults to invent their own fun. Be it adventures in the dinghy
, skateboarding ashore, walking
to the store & in general. Plus the fact than onboard you're in motion 24/7 unless at a very sheltered dock
. Which generates physical activity whether you realize it or not, as the boat's always moving.
Not to mention what transpires when you're sailing, so...
Watch the activity level of the family & kids in the video, & his comments on same. Especially when he compares life aooard & in the USVI to being in the US.
