I've seen some of these before. But, again, it's very vague as to how widespread the problem is. For example...
"One-piece grids are being used to virtually eliminate the traditional framing system, replacing it with a liner system that is literally glued into the hull. Glued, you say? Well, they call it bonding putty but an adhesive by any other name is still a glue.
Those of you experienced with Hunter sail boats will know what I mean. They were one of the first to use full interior grids, albeit not necessarily a liner, and much of their product line suffered massive bonding failures, including their large 60 footer.one of the largest boats built with a full grid/liner was a Hunter 60 that experienced total liner disbonding and failure. Yet even their smaller models were widely known for liner failures....."

First impressions are often lasting ones, especially when they are negative impressions like my first experience with Hunter in the early 1980's. Back then I had been hired by an unfortunate Hunter owner who had a forty footer with a grid liner that all came apart, causing some serious structural problems. At the time, Hunter had just converted to the use of grid liners (one of, if not the first to do so) and were far from perfecting the method, once again proving my point that far too many boat builders perform their experimentation in their product line, at the expense of their customers.
This seems to be focused on the early '80's boats. And in that regard, I assume we are talking the initial shift from the vaunted Cherubini design/builds, to the Legend design/builds?
However, let's look at the general mindset of Pascoe:
Now, I don't know about you but I've never seen anything that was glued together being as strong as a component that's all of one piece. That's despite all the loud and fancy the advertising about adhesives.
And what about this "Hunter 60"? Is he talking about Hunter's Child
or Thursday's Child
...the 60'ers that Luhrs raced (and set many records with - e.g. - OSTAR)? It's a freakin' racing yacht.
Thursday’s Child, an Open 60-foot ultralight singlehanded ocean racer, was designed by Paul Linderburg and built in 1983. In 1984, Luhrs set the boat’s first record in the Observer Single-handed Transatlantic Race (OSTAR) from Plymouth, England to Newport, Rhode Island in 16 days and 22 hours.
In 1988 and 1989, Luhrs sailed Thursday’s Child from New York around Cape Horn and into San Francisco Bay. It took him 80 days and 20 hours, creating a new record for the first time in 135 years.
A revised 60-foot boat called Hunter’s Child was built in the early 90s and raced in the 1994-1995 BOC race. Skipper Steve Pettengill and Hunter’s Child came in second place after completing the race in 128 days.
Look at the hull/structural failures of the most recent VOR boats and tell me how that relates to a cruising boat.
Apart from these examples, I'm not seeing a line of 60' cruising yachts in the Hunter family. Granted, I know about the hull flex issue with the 54's that required the structural add-on, but this ain't those.
So sorry. I'm not putting much faith in this Pascoe dude - "surveyor" or not.
Keep in mind his perspective is obviously a bit skewed...

Boat Review* by David Pascoe - Hunter 28
We're still on a single 40'er that had grid issues. And this is a "widespread problem"? Sorry Pascoe. No dice.
Last winter my boat mysteriously developed severe cracks in its hull. Some of the cracks are 1/4 inch thick and 10 feet long. The hull now has no structural integrity and is completely useless to me. It seems their Advanced Composite Process hulls can't withstand extreme temperature changes. Even their owners manual tells you not to cover the boat with a dark boat cover - I guess they know the heat from the sun might crack their hulls.
I've done some investigating and found that the product they use (BASF Luran S) has a coefficient of thermal expansion that is far inferior to other common boat building materials. Morover, it appears that this website has had dozens of Hunter owners who have experienced the same problem.

This is a 17' daysailor that was stored in sub-zero weather in freakin' Ottowa. It has absolutely nothing
to do with a cruising sailboat and grid issues.
So - this is my point. If this is what's fanning the anti-Hunter hysteria, people are far more gullible than I'd hoped.
I'm not saying Hunters are problem-free (e.g. - the rudder issues, etc.). But there is DEFINITELY a ridiculous hysteria to it all that has absolutely no basis in reality.
Keep Googling Paulo. This stuff so far is seriously lame. And, stumble, if these are the incidents informing that surveyor's "cheat sheet" - NAMS needs to have a serious look at that doc. It's giving them all a very bad name.
