My joint hull have verdigris and previous owner wasn't fix

[hoastonge]

Where we have a ladder to climb on bord just where the hull joint, the previous owner put some a joint of silicone but it turn with verdigris
Do you know if I need to have a joint of silicone there or should only remove

I never see another one Hunter 336 close enough to see if it's the same problem I have, appear on each Hunter 336

Anybody can tell me if he had this problem and how he fix it

I take it you are referring to a bead of silicone placed in the rub rail. I have seen this once before where the owner of a Hunter 28 had placed silicone in the rub rail around the entire perimeter of the entire boat. Looked like absolute hell with all of the silicone having turned green and coming loose.

But no, I can't see any reason for it. The rail will slightly squat below water when the boat is under way and the PO may have figured this was a problem. Sealed it for some reason of which we'll never know why.

Also attached is a pic from Hunter showing the two pieces of the rub-rail assembly.

This is exactly what i try to say . should i just remove it, clean all spot of slilicone and just leave it without silicone
Pervious owners, put some silicone where you put arrow on the second pictures
should I suspect some leak or is impossible to have some water leak where you show me!

At times there were some joints that would open up. What the po was trying to do is put a small bead of silicon on top of the rubrail to point the water off vs. going down thru that joint underneath.

As shown in my previous cross section of the rub rail, the small bead of silicone won't keep water (either rain or sea water) from getting behind the rail. Rain and or sea water will enter the rail further away and run down under the silicone.

- Get rid of the silicone.

- Take a look inside the hull through the starboard side hatch and see if there are any leaks.

- Is the deck/hull seam covered in fiberglass from port to starboard ?

- Place a small stack of newspapers along the seam to see if there are any leaks.

- If there is a leak, dry everything out and paint with several coats of epoxy resin (best) or fiberglass resin (good). Don't bother with cloth. This will seal faaaaaaaaaaaar better than a small bead of silicone.

Hi Dave,

I can only speak for my own 1999 H-310, but on the inside of the hull at the transom, the deck/hull joint is very nicely and heavily glassed over from one side of the hull to the other. All other sections sections of the joint are exposed and visible. Seeing as how this section of the rub rail is underwater when under way, I suppose Hunter figured they would play it extra safe and ensure the small amount of hydrostatic head wouldn't find a small leak to force water into the interior.

Years ago, I had a microscopic worm hole which penetrated the deck/hull joint and the thick fiberglass cover to allow drops of water to appear under the rear berth boards on very rare occasions. Would disappear for several years and then re-appear. This was without a doubt, the most soul crushing leak I have ever searched for.

Thanks Everybody, off it comes!

Over the years I have seen a lot as a former dealer. I am not sure about the hull to deck joint but some did apply silicon some nicely and some not so nice. If there was a leak, some folks found it was a pain to take the rub rail off which of course met taking out a lot of screws vs. one and the easiest was to apply silicon just above in the top edge to keep rain water from above penetrating that pesky leak. On some with the hull to deck joint lips coming out vs. the one where the top deck lip comes over, some folks were tired of the leaves, dirt and so on from getting underneath that style rub rail.
