Only another 11 months and visiting the Isle of Wight will be travelling outside the EU 
....Is this out of date?
Well, the EU site linked above quite clearly states that to re-set the clock, the boat merely needs to leave "the customs territory of the EU." It's difficult to imagine how a boat could reach, say, Réunion without doing so. Jersey, as MarkJ explains, can be reached with or without leaving the customs territory, depending on route taken.
According to
https://ec.europa.eu/taxation_custo...al-status-eu-countries-certain-territories_en
Channel Islands are within EU customs area.
Post #17:
"Whilst not being part of the EU, they [The CIs] are actually in the EU Customs Union, but not the EU VAT area."
The advice given by HMRC to the OP seems to rely on the notion that while the CI's are in the customs area, some of the waters 12+ miles from them are not.
