Author Topic:   22 Revenge--Water In Hull

frankb posted 08-04-2003 09:21 AM ET (US)
I'm a newbie Whaler owner who just picked up a 1985 Revenge.
The boat is in relatively good shape for its age with signs of obvious use. I discovered that along the keel the fiberglass is worn from what appears to be someone either riding the boat hard onto the trailer or the boat sitting on the beach. The area of wear is damp to the touch and drips ever so slightly.
The transom has some stress cracks on the rear edge where it [meets] the side of the boat that are covered by some tape on pin striping. When I press on the pin striping a small amount of water (not clear/yellowish/brown) will come out. Pressing on it again minutes later it will do the same. This is fairly high up on the boat. How concerned do I need to be about water being in the hull? The boat has been in the water for the season prior to seller pulling boat. I would like to salvage some of the season here in the Northeast and am curious if I should repair now or can I wait til end of season. Any thoughts or advise would be greatly appreciated.

You need to be very concerned over water in the interior of the Unibond hull. This is the worst problem with older Whalers.
Damage to any portion of the hull that is submerged that permits water to enter the Unibond hull can ruin a Whaler. Particularly important is damage that can allow water flowing a high speed to begin to destroy the bond between interior foam and the thin hull laminate shell.
If you have any damage to the gelcoat the reveals the interior laminate or foam of the hull, you should not delay in repairing it and making the hull water tight.
It is extremely difficult to remove water that has been entrapped in the interior hull foam. No one has reported much success with this. Various methods that have been tried include vacuum pumps and numerous drain holes.
I would haul the boat and repair any damage in a workmanlike manner.
Then I would conduct some tests to try to determine the extend of the water entrapped in the hull. With the boat on the trailer, crank the trailer tongue up high so any water will tend to flow to the stern.
Next I would do is to drill a 0.25 inch hole in the transom near the keel centerline and low. If water begins to flow out, you have an indication of water in the hull and in the wood of the transom.
Tap with a soft faced plastic hammer to find any soft areas.
Let the hull dry out as much as possible.

How about posting a link with some clear pictures to illustrate the areas of concern. I'm wondering whether there is some delamination allowing water to get between the foam and the skin.
