I own a 25.5 1984 Hunter. There are six (6) brackets that hold as many posts dedicated to the lifelines on deck. They are made of cast aluminum and are very brittle after all this years. Some of them cracked and broke. After looking for replacements without any luck, I had them welded. Well one of them broke again, and it doesn't look good for the others. Does anyone have any useful information?. Like if they are available somewhere, or if there are replacements.Any tips would be very much appreciated.
