To be fair to them, they have been full time boaters for 2.5 years now, and have previously owned another boat before this one, and are pitching their videos at the 'uninformed' more than seasoned boaters, so are bound to come off with a bit of a "know it all attitude" to people who have been doing this for decades.
That said, I don't really understand the opposition to the boat so much - sure, it's way overpriced, and doesn't have much in the way of 'heritage' value, but apart from that it's a far nicer boat than some of the ones we've seen for sale.
At the end of the day if they can get top dollar for their old boat due to their profile & following and thus have more to spend on their new one, well who can blame them for that?
