I'm not a fan of carry handles and I have a gen 3 V10, so my boat came with 2 carry handles. As a means of carrying an 11kg boat they really are a bit of overkill. Sometimes my 10yo daughter will meet me at the waters edge and offer to help carry my boat home. Then they're handy.
The thing is though, when you are punching out through some surf, if you get smashed, they are bloody handy to grab and keep the nose ducking under waves until you get an opportunity to remount. As for carrying a boat, I wouldn't bother. As a means of controlling your boat in surf or even swimming to shore if something breaks, I think I like them
