Default Hull Life

this might sound stupid, but is there a life expectancy for a fiberglass hull in salt water. or do some last longer than others, due to materials used or type of manufacture? thank you George

Probably the way the hull is taken care of and ran will determine that.

They are all correct. There are PT boats from WWII still motoring around. My Hatteras was built in 1967 and is still like a tank, my 1978 Robalo is good as gold.

Fiberglass lasts a really long time.

The core materials will usually go "bad" way before the fiberglass will. Wood, foams, gels or whatever other fancy items suffed in bad locations will rot out way before the glass/resin will have problems. Water can get between these layers & freeze causing delamination of the glass.

But, if the builder used crappy construction methods, the effects on the glass could be evident pretty darn quick. Stress cracks (major), deflection of the bottom, & delamination, the grid liner seperating from the bottom....

Edit:

That being said, my 1976 John Allmand's hull is solid as a rock. Real wood stringers (not plywood), wood bulkheads & a 1.5 to 2" thick solid glass bottom.

Allmands are not a fair comparison to other boats!

Yup, an Allmand is just a Bertram without the fiberglass tanks & the $$ price tag......

GA2, do you have a particular boat in mind? Gotta keep an eye out for blisters, too.

Hell, the fiberglass hull part itself will last at least forty years if it isn't abused.

A fiberglass hull will last much longer than 40 years.

Here's a picture of my Bertram 1962 (45 yrs young). The hull have been painted and the bottom had a barrier coat job, but the hull is very sound and very dry. Bertram used hollow fiberglass stringers in these boats. Well ahead of their time!

ian_upton, Beautiful boat. Deep V, yet classic styling and I love light blue hull sides.

GA2, I don't know if Sea Rays are constructed the same way that they have been for the past 30 years, but for some reason, up on Lake Erie, it's common to see Sea Rays from as far back as the early 80's, if not maybe even from the 70s. I asked a guy that runs a local marine shop and who's Father used to be a very large Sea Ray dealership in the US, why I see so many old Sea Rays still going. He told me they it was because they had so much glass in the hull, shot in with the chopper gun. He said they were heavy boats for that reason. I'm just telling you what he told me.

Back in 1962, this boat originally came with twin Volvo's. Apparantly all Volvo's of that era were left hand steer.

The boat unfortunately came with the two non-counterrotating drives. She was repowered in 1985 and I'm not even sure that Merc made counterrotating back then.

The classic styling of the Bertram and the Deep Vee are pretty timeless.

Ian.
