All the boats I mentioned above are way stronger than a Westsail or an Irwin etc.
Depends on what you mean by "stronger".

If you mean "stronger" as in surviving a tow off of a reef, my money would go on the Westsail.

What sort of "things" are you talking about?

At that spot, just aft of the keel, the hull is about 2.25" thick of which 1" is balsa core and 0.25" is copper clad muck (sore point) so there is an inch of fiberglass: 3/8" inside and 5/8" outside.
This is the strongest cored section, but there are sections where the core is tapered out 12:1 to a solid laminate like around keel, rudder, propshaft-strut, bow etc. that is even crazier. Also, the turn of the bilge has an additional 3/8" of kevlar laminate on the outer shell for extra abrasion resistance. Pretty awesome I think

I knew it wasn't gonna take long before a Westsail reaction I understand that you think a Westsail is stronger and for towing off reefs they might well be... but out sailing in the big waves and getting slapped around while doing so is where it counts more, because sitting on reefs should be avoided imho.

The über-class of yachts get away with falling off 30' waves while driving at them with 11 knots. Or eating up a dock they are tied to during a hurricane, while the dock will eat a Hunter trying that. Those kind of things. I've seen these...

Must be really quiet down below when under way , thats the thing I notice most about a cored hull over a solid one, that and they are much warmer up here in Canada .

Hey, you were the one using the broad term of "stronger".... so.

And no, I am not one of those who thinks a Westsail is the "strongest" boat. Do a Don and search my posts. I dont defend, nor bash them. Nor do I bash other boats (well, maybe Mac26s ). But this is a thread about hull construction quality. I think a reef would be a better test of such "strength", not falling off of a wave.

Or being blown off boat stands in a boat yard. I have seen two Hunters blown off their stands during really bad wind storms. Both hit the pavement on their sides. Both were a total loss (according to the insurance company). Reason? Large cracks formed in the hull (you could see daylight through one).

I think that being on a reef is very unwise for any boat. I would choose steel if this was the test. Sailing out there during bad weather is much more realistic for boat strength tests than being on reefs... for most of us, that is

A Westsail might not be blown of her stand so easily but I bet it would be a total loss too if it happens. The extra weight will generate a much more violent crash and every rib of her would break I imagine...

I would sail off in a Westsail too , don't get me wrong, and I understand that you haven't been bashing Don's Hunter either, but there have been members, in W32's IIRC, that were bashing Don in the past; I do remember the case he just brought up, and I think that was unfair because the guy would swap his W32 for that Hunter in a flash.

cheers!
Nick.

Or find one that already has. I am sure the insurance company will sell it to you CHEAP.

In the theme of Hunter discussion a Hunter 50 was tested/promoted in latest Australian Cruising Helmsman mag.
It was headed for Tasmania to replace a Hunter 45.
