F32 Hull Thickness

Post by captainmaniac » Sun Oct 27, 2019 8:01 pm

As promised, here are a few shots I took of an F32 being savaged (not salvaged... but savaged...) .... Based on the Trojan graphics and vents, it was probably a late 70s / early 80s vintage.. like my '79. Didn't check the hull number. After the fact I wish I had gone back to the boat to grab a tape measure, but at the time it was a very hot day and it was a loooong way away... The key used as a gauge in these shots is typical house key - by my measure 1/16" wide.

Apparently limited to 7 attached inline files, so will pass the last 2 up in another post.

Railings were cut off the boat by sawz-alling around the stanchion bases. You can get an idea of the toe rail coring / glassing from this shot. Those of you with an existing Trojan "SLING" sticker can get an idea of plywood core vs glass thickness.

This shot is of the hull side near the chine, and likely a sign of bottom thickness. Took this shot facing straight down on a section of hull side where it was cut off maybe 4" from the actual chine. My guesstimate is its about 9/32 - more than a quarter inch. SOLID GLASS.

This shot is hull side a few feet up from the chine. Not the best shot, and not the best light, but would say hull side is more than twice the width of the key.... so 1/8" to 3/16. Again solid glass, not cored.

This shot shows hull side thickness is pretty consistent in this area for most of the hull height.

This shot gives a better idea of where my 'lower' hull side depth near chine was captured. You can see some variation by section but it is unclear if this was a conscious decision by Trojan or just variability / lack of consistency in layup boat to boat.

This shot shows one of the other sections near the chine that is a bit thicker. I gauge this area as more than 3/8" and nearly 1/2" thick (0.4" actually). Again, SOLID GLASS

This shows where that last shot was taken from ... if you count from the right, this was the 4th section... 5 sections show in this shot.

This is a shot of the transom. By my estimate 3/8" given the key is 1/16".

Not sure what he was cutting out, but this is the location that sample was taken from (low on the transom, center line, near where most F32 swim platforms would have been). Note, she was NOT a 'Luck Lady'...

Originally I thought he cut out the forward through-hull /drain plug, but this pic shows clearly not. Don't know why he cut that hole, but you can get a sense of hull thickness forward. That's probably pushing 3/8 to 1/2 inch or more. Again, solid glass.

Lancaster most definitely over enginnered a great deal

I became a believer and continue to be every time I cut into something

IMHO that is why the Internationals actual weight may have varied from the published weight

Perhaps Bob Cushman could get a response from John Leed on that item

Take a look at the photos below

10 meter Express - galley area

The Schoell design was to strengthen EVERYTHING by tieing it together

look at how the galley is tied to the fiberglass coming off the side in a sandwich

These cuts were done to upgrade the galley sink and stovetop
