What do you think? Can help me with your suggestion?

I think that's a really interesting idea. Keep in mind that this would be a really niche area of YouTube, so you'd probably be getting some very good search rankings for things like "boat vlogs" and such, but you're probably going to have a fairly slow channel growth to start out.

Hope so
But first i should see my dad responses. Hope he can record good footage, different kind of variety and so on.
