Fiberglass boat leaking with no holes

I have an older hurrican deck boat and it has started to leak. I have checked the hull and can find no holes of any sort. I have filled the hull with water and none comes out. I am at a loss. The only damage i see is the gel coat has been scraped off of the keel for about 2.5 feet. the fiberglass in this area looks to be in goog shape.

Does anyone have any ideas or can you refer me to anyone that may be able to help?

try putting some food color in the water ,maybe youll see it easier if it a white hull

Good call. Remember, polyester and gel coat are water resistant but not "water proof". Water gets in. I had water getting in along the seam between the hull and shell, on a boat, well above the waterline. But, water still was getting in. Sealed it and... no more water.

Filling a hull with water while on a trailer puts enormous stresses on the hull.

How much water?
How fast?
In what conditions / situations do the leak happen?

check around the rub rail on the boat not sure how deck boats are designed, but on my boat the silicone had cracks in it at the stern of the boat on the port and starboard side allowing water to come in at times… had me confused for awhile…

If it has a Live well Check the Lines

Had the Same Problem with my Stinger pulled my hair out till
I plugged the Live well (Out Side) and Filled it with RED</font id=“red”> water

Low and Behold the hull filled up with red</font id=“red”> water overnight

cbroadway,

Check the rear drain line that runs from under the back seat to the stern of the boat near the ladder. This summer, the bilge on our Hurricane was running very frequently and we looked around for a while. After pulling up the aft hatches, we finally found the hose was no longer attached to this drain. Any weight in the stern of the boat put the discharge below water level and water was running back through the tube straight into the bilge area. We were surprised that there wasn’t a backflow preventor or something on that line but it was an easy fix. We think that it must have came off (taken off for better access) during a service or something as the line nut was loose.

*edited for better clarification

water can easily “wick” through the exposed glass
start by fixing the exposed area
you can use gelcoat or marine tex

Hey, Cbroadway, have you opened the hatches in the aft and looked at the seam between the liner and the hull as you’re putting the boat in the water? I had a boat once, and we had a heck of a time finding the leak. It ended up being an uncaulked seam on the transom area where the liner (top) met the hull. At a certain point while the boat was being backed into the water, the water poured in, but only at a certain point, because at that point, the seam was underwater because of the angle of the boat on the ramp, but at any other time, the seam was above water. It never leaked at any other time because the seam was above water. So, what we had thought was a slow leak of a fitting ended up being a pouring gap that only let a small net amount of water in because it was only underwater for a snip of time at each launch. I only happened to find this because I just happened to have a hatch open while backing the boat down one time and saw it pouring in.

Hope this helps.
