First, rivets are used on aircraft for the following reasons, not all of
value on a boat:

- low weight per attached foot of seam than welding
- cheap and manufacturing ease of use
- thermal expansion and flex
- can be drilled out for access/repair/inspection
- welding is more expensive per attached foot than rivets


Are other opinions welcome, yes.

I think aluminum welds are fine as long as they are reinforced or the sheets
are relatively thick. Thin sheet (seam) welding of aluminum is prone to
cracking when subjected to even a little flex as compared to other metals.
Maybe someone with knowledge of metallurgy can explain the crystalline
structure, etc. My opinion is based on experience in industry.

BTW, I think flex is much more important in airplane wings than you give it
credit for. Next time you fly, note the location of a wing tip as the
airplane begins it's take-off run and watch it as you become airborne.
While flying in turbulence, watch the tip of the wing again. There's quite
a bit of wobbling around going on out there. Welded aluminum panels
wouldn't last long, nor would the wings if they were designed to be stiff
rather than being allowed to flex.

Thnk B-52. :)

I read somewhere that the wing of the B-52 flex up to six feet from
wing root to tip.

Can't verify that.

Riveted aluminum boats tend to be sounder than welded boats and as a
general rule, easier to repair. The better aluminum boats, like Lund,
Starcraft, Princecraft, are riveted boats.

Um... Are you at all familiar with the type of heavy duty
welded aluminum boats the poster inquired about?

Yep - this is the one he referenced.

200 Sea Runner Hewes Craft

Has nothing to do with the rivet/weld debate.

I like the Weldcraft boats. I think CaliBill has one, but don't quote
me on that.

I'm not that familiar with the others.

I would say six feet at least. Even the wings on commercial airplane like
the 767s and 747s flex close to that at takeoff and in heavy turbulence.

Finally going to make the plunge and buy an aluminum boat, but i am
confused. Our goal is to buy a boat that will last for many years to
come and also turn heads when on the water. The more i talk to
salesman the more BS i hear. What should i be looking for as far as
the quality of the welds, some look like art and some look like my
son
who is 12 tried to weld for the first time. Does the apperance of
the
weld matter? We are looking at a 200 Sea Runner Hewes Craft right
now,
any comments would help at this point

Thanks

I own a Lund, and the company makes a big selling point of the fact
that
their aluminum hulls are double riveted. Welding is not mentioned
anywhere
in their literature, as far as I've noticed. I've been beating the
crap
out
of the boat since 1999 and it's as tight as the day it was new.

Thanks for the feedback
I appreciate your coment about rivetted boats but my wife said noway
to riveted boats, he dad had one and it always leaked. Infact you
should have seen the dirty looks she gave one of the salesman when he
was trying to sale us on a riveted boat. What would you look for or
like to see as far as welds?

================

I have no idea what to look for with welds. Tell your wife that her dad
bought a ****ty boat, and she should not judge all riveted boats based
on
her father's bad judgement and low budget. If she's such a shmexpert,
maybe
she should be designing boats.- Hide quoted text -

I would appreciate it if you didn't talk about her that way. You
don't know her.

==================


I don't know her, but based on the information you provided, I know
something ABOUT her. Here's an example of what I know about her: She
thinks a handmade pastry from a fancy bakery is identical to a frozen
Sara Lee pastry with the same name, like "tiramisu".


Maybe her dad bought a Lund and the rivets leaked. You know nothing about
her or the boat her dad bought. Except that the boat had leaking rivets.


You are correct. The leaky boat could've been a Lund. But, that doesn't
change the absolute perfection of my analogy. His wife thinks all things
within a given category are identical. Hopefully, that doesn't extend to
men.


I sure wouldn't want to put a splotch on that perfect image of yourself,
but you might just consider a little apology.

Note to the origional poster if you are still he We are a pretty
good group, really there are only two in the whole group who jump in
with no info, trying to troll conversations into the ground and steer
folks the wrong way intentionally... Both have posted to this thread,
I will leave it to you to figure out who they are;)

The 'Old Dog' wasn't there. You should see the flex on *those* wings!

Same with Princecraft. hulls rivited...same as high stress airplane
bodies.
scroll down to... 'proven fastening methods'
http://www.princecraft.com/Content/e...ing_boats.aspx

Airplanes aren't designed for the water, bozo.

Nice job emulating Harry...If you own it, it's the BEST!

I owned it before Don did.

Want to call me a Bozo?

You neither own the Bozo's Bin nor are qualified to enter.

So quit trying.
