Absolutely Andrew, I agree. This really is a lifestyle, career, hobby, vocation. If he’s doing charters I guess he writes off most of his costs against his income but you’d need to love it above all else. It’s not a part time business.
In most of our travels around the globe and this country I always gravitate to the waterfront if it’s not where we arrive and it’s always the old timber boats that grab my interest. Stuff the super yachts. We have done a few day tours in old timber vessels in Turkey, Vanuatu and even Sydney harbour and I think if I won powerball that’s what I’d buy. Only if you were loaded and could ring up the marina and request a service , hull clean, recork and antifoul. Doing it yourself though would be a constant job. I think the rewards of owning such a vessel are obvious though.
While looking at boat vids to amuse myself ( intermittently raining so haulout stuff intermittent too

) I came across this old fellows vid on the interior for his sixteen foot micro cruiser. Not an investigator but thought his internal fitout was very clever and well executed. I’m hoping to add a few internal mods this time and I like looking at how others make interesting and intelligent use of very small spaces. I think his micro foldaway gallery is great.
Whole vid is a nice distraction from current difficult times at any rate.

DISCLAIMER Unfortunately it contains the ubiquitous “explodo” stove . I’ve written volumes over on the “other” place on these. The newer ones are supposed to be much safer and are now approved again by the relevant authorities but if you have one of the older models walk don’t run to the nearest wheelie bin and drop it in. Only should be used outside IMHO and that probably includes the newer type.
