Finer Points Between 18ft. & 19 ft. Bass Boat ?

Recommended Posts

One has to consider not all marine aluminum is salt water grade.   You don't want a fresh water grade in salt environments.   I don't think I said it couldn't be done.  He's talking a 18'+ bass boat here.   I have a Lund bass boat and it's welded...

As to rivets vs welds, welds are generally stronger, rivets have a crevice and crevices lead to corrosion.   Welding fills the seam.  Aircraft are riveted, but it doesn't matter it some air leaks in or out and adds to the flexural strength.   You don't want your aircraft to crack in half. 

There are plenty of fiberglass and steel work boats out there as well.  These are my preferences, you do what you want.   Don't shoot the messenger.

This is new to me, I’m pretty sure when your 30,000 feet up you DO NOT want any air leakage in your mode of transportation. I’ve owned several riveted aluminum boats and I’ll keep using them. 😀

There's no such thing as saltwater grade aluminum!

The new 2018 Lund Predator, which is a utility jon, is made by Crestliner and is welded.

Exactly.  ANY WATER is bad for untreated aluminum.  All Aluminum boats are treated.

Why do I doubt that this is the boat?  The point is, one can't make a statement that riveted boats being weaker than welded, and then claim leakage at the rivets helps with strength.  It doesn't add up.  And you, as a riveted Lund owner know the rivet deal is false.  Can rivets leak?  Yes.  Can a welded boat bust a seam?  Yes.  Ask me how I and two other welded boat owners know this.  There's no better, just different, and varying quality.

I think there is 2 grades of aluminum (5052 and 5056)primarily used for fishing boats neither has anything to do with type of water. 5056 is a higher grade, but the point about being for saltwater is moot.

The reason 5052 & 5056 are used is they are both highly weldable.

 

Any untreated aluminum is susceptible to corrosion & you don't need saltwater to cause corrosion, all you need is moisture.
