I have three Eddyline kayaks; Two here at home, the third (2008 Skylark) being paddled by family. The Skylark was dropped by a couple of guys on concrete. No damage.
The Samba I use for rivers. It’s been run into a few things as well as shallow gravel spots, but no dings. Just a few hull scratches.
Before I got my CD Prana I paddled my Fathom LV on Lake Michigan, whose beaches are not always sandy. Have done some surf landings into beaches covered with small rocks and once I misjudged and came into some big rocks hard. The noise it made was horrid. That landing did cause some gouges in the bow and hull, but nothing that can’t be easily filled with white Devcon Plastic Welder. I just haven’t gotten around to it. That’s one nice thing about thermoform: repair material is inexpensive and the process is pretty simple.
Now, had I hit those rocks during the winter, the damage may have been severe as thermoform gets brittle in extreme cold.
In all honesty, I’m more concerned about rocky beach landings with my kevlar Prana than I ever was with the Fathom.
I think Peter’s last sentence says it all.
