A Bertram 630 weighs over 90,000 lbs. The boat was also supposed to be traveling around 25 knots, not 40. It is reported in that thread that seas were under 6 ft. I am no expert, but in my opinion a 63 foot sportfish should not be stuffing under those conditions.

Im not buying the buoy theory as a lone cause.

Id say this, plus existing damage,plus a big wave hit - plus manufacturing defects.

Look at how the fibreglass pulls away from the core material indicating they were never fused together to begin with.

Core material should be bonded so thoroughly that it becomes one piece not a sandwich of layer loosely held together.

This is what resin infusion and vacuum bagging are employed in the mafgr process for - to insure the complete bond.

I didn't read everything on the other site, but I would think they had radar on and could have seen most anything in front of them.

yes it does and heartbeat the black fountian 33 in 94 if I am right and the power play 33 later in the 90s. but in these three people got killed and hurt, they were lucky in the 63. which I think after 55 pages hit the can that put a small hole in the port side while the can was on top or haft way up a wave and the boat ramed it above the water line and the next two sets of waves caved in thr rest of the hull and deck. if they still make those boats out of polyester resin and coring that sucks. for a 2.5 million dollar boat it should be all glass if using polyester:lolhit:. most high performance boats built with coring are vinlyester or epoxy either hand layed or vacum bagged also a better glass should be used on the 63 kevlar two layers on the outside against the gel and coring. theres was a kevlar 38tg in 96 or 97 on the cape he hit a can 4 times the size of the bert one on the outside of the west end of the canal at night going 40 to 60mph it opened a 1 to 2 ft gap above the water line 7ft long. the glass guy said it was the kevar and it might of had cf in it cause there was a lot of webbing that was black like cf that save the cig he said a all glass boat would have been worst maybe sunk. well thats it for now.

hey fred I read that the new vikings are cord too:eek:.

Look at the separation.

Core material is supposed to BOND as one piece with the glass and resin. This is NOT what this should look like.

Look up the wave station reports... 8,9 and 10 feet. "Absolutely" tops out at 42 knots. 90k further makes the argument for stuffing... It's all about momentum.

Thats usually what happens when a core is not bagged or not bagged properly or is dry. Just the surface of the core is bonded with no cross linking or very poor resin penetration. Although from the pics the dark lines do indicate resin presence so its tough to tell. Man this boat really is a mess. What were the seas that day? I didnt get a chance to read all the way through yet.

oops, just saw this. Yea thats a lot of available forces there. Delams only need a small breach to become catastrophic but man this thing is a mess.

There is nothing wrong with a cored boat, if done properly. In fact if done properly the cored laminate is just as strong or stronger, with a serious weight advantage.
