Yeah, and they've even improved it to a survey every 7 years (up from the previous 5 years) fairly recently. Provided the boat has been insured with Craftinsure for those 7 years - always worth checking the small print!
I needed a 5 year survey during one of the lockdowns, and couldn't get one, so I paid an additional waiver on my insurance for year 6.
At renewal in year 7 they offered me the same waiver again, but they'd just introduced the 7 years thing (new underwriter) so I queried it ... and didn't pay it!
