THE WAR ON THE LEAKS CONTINUES - The most common culprit in the leaky boat syndrome is the window area. We have seen grown men reduced to over emotional, obsessed and possessed creatures trying to stop the windows from leaking. We have seen boats with a swath of caulk around each window that was so large, that it appeared to have a life of it's own. All jokes aside the effort to stop a window leak is a time consuming, frustrating affair. To effectively stop a leak, one must identify exactly where it is coming from, and this is the part of the process that is akin to rocket science - is it leaking between the frame and the fiberglass, or between the glass and the aluminum frame, and which window, fore or aft. The main reason windows, in the older model Catalina 22's, leak is that the window frame and the construction of the hull in this area are inadequate at best. The window frame many times does not contact the cabin securely, allowing water seepage between the aluminum frame and the fiberglass, usually because the weather stripping the window was originally set with has broken down. This water ends up in the inner core of the boat, and manifest itself through various through holes in the cabin, i.e. the light above the shelf. Another problem with maintaining a water tight seal in this area is that the hull has no reinforcing here, simply the outer glass and then the inner liner, thus any flex in this area breaks the seal. Careful caulking can eliminate the problem temporarily, and remember recaulking any hardware on the boat is an ever ongoing process. We have seen cases where removing the window and using new stripping and caulk did not help the situation and sometimes can make it worse!

The other side of the coin - leaks between the glass and the frame are prone to occur via the rubber gasket. This gasket has a propensity to shrink and break away from the frame. In the restoration of "Cattitude" we removed the rubber gasket both inside and out and very carefully caulked. This should probably only be considered when the rubber is completely degraded.

As in last months summary of what to do about those leaks, remember work smarter not harder - when all else fails, use a rainfly that comes over the windows to afford protection, this also saves the teak!!

Next months topic will be about trying to stop the windows from leaking.
