Mystery water in front compartment
|Author||Topic: Mystery water in front compartment|
posted 02-18-2003 09:28 PM ET (US)
I have a 1988 OR20. In the floor compartment that is right in front of the console I keep getting water in it. Even on the trailer. The plug is in and it holds the water nicely in there. I've inspected the fiberglass etc and no cracks, or imperfections of any kind. My likely thought is rain water, but I'm not sure how it gets in there as the hatch is closed and there are channels around the sides of the hatch anyway. I took a garden hose and let it run in the front of the boat to see if it would infiltrate and it just flowed around the channels and toward the stern. The water is always crystal clear in there. Any other thoughts besides rain getting in there? I do have a slight list to starboard at the stern. About 2 inches lower than center at the corner. Thanks

I would not consider 2" a slight list.
First, a few questions.
Do all of your draintubes (both fore and aft) that exit below the waterline have clamshells covering the opening on the outer hull?
Are any of the drain tubes excessively corroded?
Is the motor straight, (not turned to port) there anything mounted or stored in the boat that would cause it to list to port?
Are there any obvious signs of hull repair below the waterline?

How long between the water buildup? Condensation buildup is a possibility if the humidity is high and/or large temperture variations between day and night occur.
The list could be caused by a number of factors ranging from a slightly off center motor to water intrusion into the hull. Are the batteries farther to one side? So many possibilitys...

The water is probably coming from inside the hull. I suspect the drain tube in the bow locker has bad seals and water has been getting into the hull there and is now seeping out into the bow locker as it sits out the trailer.
Is the clam shell venturi in place over the outside end of the bow locker drain tube?

All of the clamshells are over the drain tubes throughout the hull. I bought the boat used last July and the bottom has 14 years of bottom paint on it. There are no hull repairs that I know of. There is no connection (drain, etc) between the bow locker and the mid locker where I am getting all the water. The boat is on the trailer and the plug in the midlocker in question seems to keep the water in nicely.
As far as the list, (yes the engine is straight- but the plug is out) the boat is lower in the starboard corner. I have one battery in that corner. I have another battery mounted slightly to port of center in front of the splash well, and the oil reservoir in the port corner. I did a rather crued experiment based on my weight and how much the boat goes down if I stand on the corner at a dock. I estimated that the amount of weight in the starboard corner is about 50 pounds. But I'm no scientist or master of physics to figure leverage etc. Right below the starboard decal on the side was a "ding" about 5/8" wide and 1 1/4 inch long. It revealed the blue matting but not any foam. It was several inches above the water line. I Marintexed it last July.
On a handheld GPS, she topped out at 44.5 mph with low fuel and just me. I run the original SS omc prop and 88John200. With 3/4 tank of fuel and 3 adults it hit 42 mph WOT at 5400rpm.
Is replacing the seals on those drain tubes a big job?
Also, with the exception of some hulls in really bad shape, is this concept of taking on water blown out of proportion? I love Whalers and had a 13, 15, and now my second 20 (all late 80's vintage), but with all the attention that water in the hull draws on the forum, I'm starting to wonder if it is a rare issue that is just being put under a microscope?
Last, just for curiousity, has anyone tried to calculate the volume of foam below the waterline and in total that a 80's hull contains to theoretically figure the maximum water the hulls could contain or to give a sort of reference point if weighed on a commercial scale?
Thanks for all the advice

a response to the questions raised:
None of the clamshells are excessively eroded. I've never really paid too much attention to the time between the locker filling up (the plug is mounted and a bilge was installed with a garden hose to throw over the side to pump it out- previous and original owner). I notice that in the summer when boat water I'll have to pump in once a week maybe. I initially thought it was just run off from people getting back on board from swimming etc. Then I noticed it on the trailer- but again the plug hold it pretty tight so I don't think water is coming in from plug when moored, and obviously not when trailered. Even in a heavy ran, with the boat level or slightly tilted back on trailer and the hatch closed I can't see how 6 inches of rain water can get in there. I can have anywhere from 3 to 6 inches of water in there. And it takes from 3 to 7 minutes to pump out with the bilge. Again the water is always crystal clear with no odors or anything eminating. I want to stress that this doesn't fill up every day (I only notice it when I happen to go into the locker for something) and never seems to exceed the level mentioned. The compartment is not attached via drain to any other compartment in boat and the interior gel coat etc is perfect.

I see references to drains and clamshells/covers. I am a new Nauset owner. My boat is under shrink wrap and I am waiting for the weather to break so that I can start going over every inch of the boat. Meanwhile, I am completely in the dark on these drain devices. They sound very important. Where are they located on a Nauset ? Any information you could provide would be greatly appreciated.

Run the hose again, those gutters are not the greatest.
Had a similar problem with my 22.
It was the caulk, or lack there of, for the main cover panel over the tank. It did not extend far enough under the removable hatch cover. One side even had a gap that would let water right into the well, especially when the water was backed up by the cooler and chocks. I taped it off and extended and widened the caulk up the channel towards the bow under the hatch and solved the problem. Can't see it.
You could keep origami made out of the rice paper Grasshopper walked on down there now.

I agree with Chap. After reading his description, it reminded me of a fix that Whaler offered. I believe they made up a repair kit for it. I doubt it's still available, but they may have the instructions.
The location of your accessories is probably enough to account for the list.
Water in the hull can seep back in even when the plug is in place because it comes out from between the fiberglass and the tube. The volume of water and the fact that it's crystal clear suggests that what you are seeing is rainwater. Hull water will have a distinct odor like resin.
It is a common problem for many boats with below deck lockers. Even though they have gutters, water will find it's way in. At some point, the volume of rainwater is likely to exceed the capacity of the gutters.
