Section 19 - Anchor Connections
I doubt any of the kayak manufacturers advertise or guarantee their carry handles to be for anchoring purposes. I strongly advise you to rig a safety redundant system for the anchor line in the event the kayak handle breaks loose. These photos show how to connect the front leash to the kayak handle and the two backup lines to the eyelets. The leash is long enough to reach the backrest to put it at your fingertips. Connect the clip to the backrest hardware while paddling.
Another option is to permanently connect this leash to the kayak by using the eye-splice knot thereby eliminating three of the four clips involved. I use this method because my kayaks are on my truck all the time and I don't want to leave anything that is easily "borrowed."
These photos show the rear leash connection which is the same as the front, with the exception this leash has a floating ball and brass ring at the end. This allows for an easy hookup for a second kayaker. Without this setup, the second kayaker would have to connect to the rear handle and two eyelets, then disconnect after the dive. Having a single target to deal with is much easier, especially in rough waters and offers a "no bumping" zone between the two kayaks while connecting and disconnecting. This leash can rest in the tank well while paddling and the second kayaker can knock it in the water with his/her paddle when ready to anchor. Or, just let it drag in the water.
These photos show the front leash connections of the second kayak. They are the same as the lead kayak. The brass clip on the free end is larger than all the others because it offers easy connect/disconnect to the floating brass ring at the rear of the lead kayak. This leash is also long enough to reach the backrest so it is at the users fingertips.
The left photo shows the wear on the hole for the front handle on my older kayak. I replaced the handle cord with a softer braided nylon one to minimize the friction wear. For safety reasons I hook the leash to the rear of this kayak so the second kayaker has to hookup to the lead kayak backwards. The newer model XT has more material around the hole. Ocean Kayak apparently saw the need for some improvement here. Although I like my XT's, I think this is still one of their weak points. This is all the more reason not to carry these kayaks by the handles with the added weight of gear in them.
If these holes break through, you would have to install an eyelet on the end of the kayak for the handle as shown in the below photo. Ocean kayak is now doing this on some of their other models in lieu of the molded handle hole.
