That is what we did in Europe mainly through GDPR. And we got rewritten software in Chinese cars. Yes it slowed down the rollout of Chinese cars (or at least their advanced features) but the big brands are now nearing feature parity with the domestic models.
Canada could simply demand the European software. And the European models.
20-30ft sailboats are hardly what you think of as ocean going or “blue water” boats. Most people cross ocean on larger boats over 30ft.
sailboats are increasingly easy to electrify. Tho I have no data on how many people do it. There are huge benefits in going electric and the tech is becoming quite mature
That said most boats you will see out there owned by real humans (not charter companies) are 30+ years old with 30+ years old motor in them. Sailors rarely replace the motor unless they absolutely have to.
Sails boats definitely. Day cruisers /small motor boats also. I think the big motor yachts less so at the moment. They demand range in thousands of nautical miles which is tough.
Sailboats usually motor only occasionally. Not continuously for weeks to cross an ocean. So it’s easier to not worry about range and plan around it.
Further EV sailors love that they are generating fuel out there in the ocean from regen on the prop and from solar. Remember no one will refill your diesel tanks in the middle of the ocean.
Honestly same goes for propane for cooking.
Going electric on boats removes multiple complicated and flammable systems with one.
A big battery bank, solar, electric drive and electric galley (and water maker) and you’re set. You can go off grid for as long as your food lasts.
