This is just to caution about aging hoses used for the seat drains.  My 1989 had corrugated white tubing 1 1/4 ID.  I have often had unexplained water in the bilge and each time I had water in the Laz I chalked it up to clogged seat drains from leaves or gumballs etc.  that came along when my winter tarp getting shredded by storms.  Recently a tropical storm came along as my tarp was reaching the end of it's life and exposed the stern area.  I came to the boat to find the front of the trailer completely off the ground and the laz. nearly full of water.  I discovered the drain hoses to have cracks and they were fragile as eggshells once I started handling them.  Clearly they have not had sun exposure but after nearly 35 years the plastic is done.

Just another thought, about 10 years ago in Colorado one of the racers in the club had a brand new boat ,  22 ft I think, can't remember the brand. Anyway, he capsized in a race, got towed to shore.  They righted the boat, got it on trailer, and as they were pulling up the ramp the weight of water in the boat slammed into the stern and basically removed it (stern
fiberglass).  So be careful if you ever have a laz full of water....
