If indeed one hull takes the "usage" alot better then the other then that is cause for some investigation. At least that is what I think. The two hulls may indeed be expected to handle the same "usage". But like the others I too feel that at least a portion of the damage is due to improper handling. But that doesn't explain away the claimed difference between the two hulls.

Will, it there any potential for using some small timber ramp or something at your sailing location. Possible covered with a layer of carpet ?

Is the lake shore totally "wild", or do you guys have some "club" facilities ?

Otherwise a small anchored bouy will do the trick for you, even in very strong winds. The same setup was used at the resort Wildwind in Greece were over the years I've been several weeks in total. Each afternoon the wind were 15+ knots with often gusts to 25+ knots. They too had a rocky beach. The procedure was to sail the boat up the bouy and hook the line to the bridle strop or the spi pole just underneath it. The boat would then weathervane and you can take your sails down. Then you go back to sure and pick up your cattrax (that were chained to your trailer to prevent being stolen), You place the cat tracks under the boat and unhook the boat before walking her in. Possible lay some foam blocks or wooden planck on shore where you park the boat before taken the mast down or put the boat on the trailer before taking the mast down (don't forget to tie the boat down first). The is the way many sailors do it.

By the way this resort used mostly glassfibre boats like the Tiger, Fox and FX-one and these do indeed handle abuse very similary to the F16, "not very well" that is. The procedure seemed to work for them very well and I found it easy enough too.

Nearly all travelling F18 sailors have procedure very similar to that with the exception of the small bouy as that is the crews job then.
