I've gone over a few Sabre insurance auction
boats I was looking at to turn over and was impressed by the quality of construction on them. Sabre in general uses good quality building practices and turns out a quality product, which is reflected in their resale price
I've not heard of any core issues with them from the surveyors I've talked with or several people who've owned them, I did a bit of homework on Sabres when looking for one for a friend.
Having owned a couple cored boats in the past I am not concerned with cored construction unless a previous owner has modified the hull by adding through hulls without going the extra mile to seal the area around the newly cut hole.
More likely issues exist with cored decks, on any boat which have not had the deck hardware
regularly maintained and re-sealed.
Of course like any big purchase
, hire a good surveyor who has experience with cored hulls.
The cored boats I owned were both cored above the waterline so it wasn't an issue there.
Whether cored or not, it's worth hiring a surveyor to go through the potential purchase, just remember, all surveyors are not created equal, ask around for refferals from actual past customers of the surveyor you pick. I've found a wide variation in skill and experience level over the years, find one who has lots of sailboat and cored hull knowledge. It's worth keeping the one you hire honest by going through the survey with him or her, you both may learn something in the process.
The surveyor I hired last year for our latest boat was excellent but I still made sure I had concerns in certain areas which helped him give it a little extra scrutiny. On the other hand a friend of mine purchased a boat his surveyor gave the thumbs up only to find the radar
, depth sounder
, and auto pilot did not work, even though he assured him they all worked, apparently he just took the owners word for it rather than testing it, we later found the water tanks
leaked, The fuel tank
had problems, the starting battery
was not tied down or contained in any way, etc, etc, etc, all these things were obvious, unfortunately the surveyor he used didn't see it, yet he still charged the same rate as others.
