The question as I understand it is not how long the boat is top competitive but how long you can sail it if usage is "normal". I totally expect this to be 20+ years.
Exactly. Sure the Laser guys buy a new sail every regatta, a new mast a couple times a year, and a new boat every season, but none of the "old" stuff goes into the trash.
I am fairly isolated here. I was not aware that knees, elbows, ankle bones, etc could dimple a boat. A bit of any eye opener. I had a dimple on my boat before it ever got on the water. There were no other boats around me that were this tender. So I was wondering if I was being introduced to another fact of life.
