There is a relation between rivet head size and rivet diameter in the
industry. Just like the relation between screw diameter and minimum screw
hole depth.

Dave is a good engineer.

That's what I thought, they use SS screws and nuts with washers do they

not? However I seem to recall earlier Bennies with rivits.


Anything's possible, but every first series I've seen had SS screws and
that's going back to the early First 38's. This fellow claimed he saw a
first series, then claimed it had undersized rivets after saying he
didn't know which boat he was actually on. All had toe rails that
looked identical to any others I'd had on my C&C. He claims to be an
engineer person, yet he was able to judge the rivets as undersized with
only seeing the tops and doesn't even know what they were made of,
except that they were finished to match the rail.
Yeah...some engineer type. Keep him away from my boat. I wonder what
kind of boat he'll claim to own.

I assume you mean the 8.6. Never heard an S2 owner call their boat a 28
or 36? Welcome to the world of the leakiest windows in the free world.
I have turned down 3 S2's for brokerage due to water damage from those
ports. Otherwise an okay boat though even slower than John's Catalina
28. Not my cup of tea...left all that stuff behind with my Catalina
27...thank god!

My S2 is the 8.5M. Odd, my windows dont leak. I have heard of this
problem but have not had it happen.
My comments about the toerail on the Beneteau are based soley on a look
at from the exterior as I have noted before. I noted them because the
rivets had the same aluminum looking finish as the aluminum toerail and
I wondered if this was due to compatability problems with ss bolts and
an Al toerail although this was never a prob for me. I further
wondered if these rivets (or bolts although they looked like rivets)
were an Al alloy I had heard about with tensile strength greater than
steel.
There may NOT be anything wrong with rivets but in the late 80s riveted
toerails had a bad reputation for failure with rivets popping when the
toerail got hit. By the 90s, perhaps the problem was solved. I had
seen such rivets on old Irwins and the el cheapo Ventures.

Also bear in mind that blind rivets are but one style. In short, you
can't tell much of anything about a rivet by looking at the head,
except to know that the head is bigger than the shank.


Engineer types take notice! But maybe he quickly reached down, yanked
it out, measured and tested to see if it was high grade SS and so on.
Being the Engineer type I bet he also counted them and observed the
spacing for load distribution.
Yup...he's the engineer type alright.

I never heard anybody call the 8.5 M S2 slow. Interesting, is the 8.6
that different?

Maybe everyone you know sails Coronado 27s.
On the LIS your boat is rated 192. That's slow. A C&C 27 rates a 180. A
Cal 28-2 rates 180. Hunter 28.5 rates 183. J 28 rates 177. Tartan 28
rates 180.
Need I go on?

One can also tell by looking at the head if it is a blind rivet or not, the
type of material, what type of load it is designed for (sheer vs tension),
and a whole host of other factors.

Maybe you can't tell much.

Anemia takes it toll.

Amen!

I guess this would all be very interesting if only my 35s5 had rivets
in the first place. It might also be of some interest if our resident
"engineer type" had a clue as to what boat he was on.
Ah well. I think this one's finished.

When it comes to engineering I'd trust his opinion over yours.
You can only rely on other's opinions and experience or very simple first
observations on your part.
You can't deal in higher order abstractions or the application of principles
to problems.
In short, you have the problem solving skills of a chimpanzee.

Amen!

Right you are Marty,

The early models used the rivets and were a source of trouble. They
changed over to the bolts. Seems to have cured the problems???
