That was my assumtion. just making sure. Its a misleading test, as it shows nothing about the hull to deck bond. Everyone with loose rub rail screws is going to think they have a major issue, which may or may not be true.

Your picture however is troubling. Thats why I asked where it was on the boat.

How is that a misleading test? There are screws every 18 inches or less. In my case I double the screws since it was "loose". If the rub rail moves, or you can push the hull in........PROBLEM. I guess we need to post a video demo? :) Next hull we find in SCOPE! :drink: :eek: I'll ask the owner about where that pic was taken.

Absolutly, if you can push the hull in, you have problems. Loose rub rail screws don't mean anything, except maybe that the owner didn't do any maintaince on his boat. I used to have to tighten mine every year. If you didn't do that for multiple years, I'd be surprised if they didn't all come loose.

Telling people that loose rub rail screws is a sign of a bonding failure is misleading at best. Everyone that has loose screws is going to panic and think they have a major hull issue, when they may or may not.

If you remove the rail, and the through bolts are broken, or as you said, if the hull moves in, thats a problem.

As I said, that shot of the Plexus is very bad. Thats why I asked where it was, or for a wider picture. Based on the pictures and videos I have seen of Formula applying Plexus, that looks like its the whole bead that "missed", and it shouldn't have "missed"...

Sorry......I miss read your post. The only loose rub rail screws I have had are because the head of the screw (under the rub rail) came off with the broken screw.

Are you indicating that you need to periodically remove your rubrail and tighten the screws holding the deck?

The pic doesn't show there isn't plexus in the joint, only there is plexus on the hull. Maybe the guy sneezed and started a new bead. You need to look between the joint.

They do not realize the seam may be breaking the screws. I will be very surprised if now that this is public that when the rest of the country thaws out we will hear from more owners.

BTW formulas comments about operator error is really BS. 4 of the five owners are SCOPE board members and past presidents of the club. I am the least qualified with 35 years of OCEAN powerboat exp. Although it did not take long to learn NOT to run at speed with one tab at 2 and the other at
8 !!

I was VERY VERY VERY disappointed that a leader in the industry would stoop that low to pass the buck.

One of the boats was leaking when running into weather. This is how the owner found the issue. The water was entering the cabin through the seam......How many 382 owners have mysterious water leaks??????

Guys, the key word here is "may". The rubrails were the leading indicator of the seam issue. I AM NOT saying that all rubrail issues are as a result of seam failure

Plex photo
 
This photo was taken from the engine room forward of the starboard engine. When we pulled the rail and repaired the joint there was NO PLEX in this area NONE!. In general on my boat there was not enough plex in the seam.In most places there was just one line installed and then over squeezed. Upon repair we installed enough to squeeze out the top and the bottom of the seam. Plex wants at least 1/8" of material left in the seam, careful not to oversqueeze! As you can see there is no plex squeezed from the joint forward of the gob. Operator error...yes I agree..

Dave......how did you get the deck and hull separated? If done correctly, that Plexus joint is "inseparable"!!! You'd rip the fiberglass first! :D
