Again, there are all types of rigging and correct ways of lifting. Without going into geometry and lateral loads, those types of lifting cables and the eyes attached to the boats are designed to lift straight or on an angle and as long as they stay within certain limits. Most of the lifting eyes are designed to have very little lateral load when picked at a 45 degree angle or less. You need stronger cables as the angle shrinks however.

Good point. I wouldn't dunk my trailer in salt let alone a really nice myco or something

My guess is the foam stringers covered with one layer of 17-08 finally failed while lifting.
These light weight built boats are not built for a lifetime of service.
Be glad it failed on land , now send it to the grinder and build a new one.
There is a ton of old racing sailboats that see a 1000th of the direct impact these boats see that have been destroyed.

The bottom line is that years of being craned in and craned out of the water took it's toll on the mounting points/glasswork of the D lifting rings and failed. It does not make the boat a bad boat and is something that was not easily recognized or diagnosed. When you're lookiing for structural fatigue in a race boat you are usually looking at stringers, transoms, bottoms, etc; not the joint where the bulkhead meets the deck or lifting eye. The boat was repaired and went on to win P3 class with an average lap speed of 73+ mph..
