This is the most fun I've had in awhile!


At least these two are allowed to slug it out here on YF they would have gotten booted 5 pages ago!

So, do you both of agree the boat stuffed and came apart (for whatever reason) and did not hit anything?

Uncle first off IF you are building a boat for longevity Wood/Plyrot/Balsa is not on the input ,home depot-shopping list! Where the Plastics can be exposed to water and humidity permanently.
Now where the Behavior of the sandwich Structure under overload, Impact, fatigue. Vibrations and ETC the Plastic wins hands down.

Stiffness again Uncle not true by any measure in a well-designed panel! If anything it will be self-destructive. As if wood is used that does not have the consistency of Plastic.

And again your Data is NA where the Liner foams are concerned. Now off topic the best in Sport fishing Boats and Composite Yachts are built using Plastic Cores.

It appears that way, but until a real evaluation can be made by both sides of this it is a touchy issue.

Well It came apart for sure and looks like delamination.

With the sophistication of todays radar and chart plotters I for one find it hard to believe he hit anything.

The buoy would not only show up on radar, (from miles away no less based on the height of the array) It would also probably be on his GPS's chart.

If hes using a raster chart like most capatains seem to prefer - buoys are definately marked.

Some guys will navigate that that though setting waypoints from buoy marker to buoy marker and he could have been blindly following a waypoint right to it.

Lets say he hit the buoy. Should that have brought a 63ft 1.8M dollar bertram to the bottom? I just dont see it. Chain wrapped around a strut yanked something off, damaged the boat- oh yeah sink it? ehh dont think so but its possible.

Im a big believer in waiting to see what the testing shows, but It sounds and looks to me like the boat just buckled.

First you said it was "bogus."

When I posted Gurits data now you cant really say its bogus anymore can you?

Your hammer test is interesting but one "test" does not trump all the other measurements of strength in the third party data.

You said Sigma labs did the testing??
Is it Sigma labs data, or yours?
Can you post the whole lab report?

If you can, then we can all compare all the third party data objectively.

Im off to Home depot to see what kind of deal I can get on a Cigarette Top Gun made from crappy wood. Its probably on the other side of the Skater aisle.

Why did the D-57 and D-100 Balsa Break since by what you believe it is stronger? But the linear foam did not!
