Few areas
Bill, I've sailed a 1979 25' for 4 seasons - here's what I found to check:Mast step - check the deck for signs of compression, and if you can remove one of the through decks, look for water in the deck core there. Can be fixed, but is messy and no fun.Check for leaks in the cabin under the mast step - would indicate similar problem as above. Toe rail tends to leak, especially around the stanchion posts where water can gather. Look for stains on the cabin walls. If you can hose the boat down, dry out the bilge, wash the boat well with some pressure on deck and wait an hour and then check the bilge again. Some of this may also be coming in around the ports.Check the cockpit drain hose under the fuel locker - this is typically an L-shaped piece and if water freezes in it and the hose cracks, any cockpit water will drain into the bilge - eventually could cause a sinking if the transom drain hole submerges. Over the years we have also replaced the water bag under the cockpit - tough to do since there's hardly any room to get into the area, but luckily my partner is petite and could get in and out of the lazarette.Obviously, check for hull, deck and rigging integrity. Also check the play in the rudder post. On an older boat, chances are that there has been some modification to the electrical circuits to add other devices, so be sure you know how things run there too. I'm still tracing a couple of circuits.There's lots of other things you should check too - engine, stove, head, plumbing etc - but the above are where we found problems.Overall, we've loved sailing Windbreaker and cruising Lake Huron with her. She's a sturdy little boat and loves to sail.Good luck on your purchase.Johns/v WindbreakerSaginaw Bay, Michigan
