I built this ramp yesterday so it would be easier to get my kayak to and from the water. This allows me to put the kayak in quickly without back strain or damage to the kayak. It took about 2 hours to build and was well worth the time, as it saves me about 15 minutes of work every time I use the kayak. If you would like specific info on the build, let me know, however due to the different designs of kayaks, you may need to design your ramp differently to meet the needs of your hull. My kayak happens to have a sort of catamaran hull. each bunk of the ramp fits nicely in the concave ridges along the bottom of the hull. This allows the kayak to slide nicely and evenly on the bunks. Below are a few pictures of the build. In the background of the last picture you can see the old ramp that is being replaced. The old ramp used 2- 4×4’s and it was poorly designed and did not hold up well to the elements. The new ramp is using 2- 2×6’s that have been treated. The 2 bunks of the ramp will be adjoined by pieces of 2×6 spaced 16 inches across at approximately 2 foot increments. The ramp is then covered in carpet to protect the hull of the kayak and the wood.
