I imagine the sled material needs to be affordable, obtainable, wetable, easy to work with and slick and tough enough to slide over rocks. HDPE comes to mind. How about finding a used port-a-potty side or wall? Or large wheeled trash bin? Or dumpster lid?
Better would be a slipway… There are many to still be found on the Maine coast. Which is rocks and 13-26 foot tides… You can then have a winch at the top to control the boats descent

I thought about making some kind of slipway that runs from the top down to the water? But the tide levels and the currents at any particular time would change the best launch point. The other thing is that there are strict county rules against building docks or anything along the coast edge really. Houses with a dock were usually built in the 70s, etc and are grandfathered. Getting a new dock permit takes an act of God almost.
So I have focussed on building a sled for the kayak itself. Just using a regular kayak cart with wheels would present a risk as some of the rock ledges are very uneven and a tip over would be likely.
Yesterday I started this puzzle using an exoskeleton of rigid plastic pipe with elbow connectors and thicker flexible irrigation tubing. The cost so far is cheap. It is also light and hopefully strong. And nothing permanent that would get noticed.
I will update with pics today…
Looks like you will become good at seal launches and landings: https://youtu.be/WD6au3vEHvU
I assume there are local laws preventing you from building any structure, like a dock?
^^ Jeepers!
The other challenge I have at the lower section at the fluctuating waters edge is the wet slippery eel grass and other plant life that gets exposed during tidal changes. It would be just a matter of time until I broke an ankle. So, what I came up with is this: I found (at a box store) these large thick 3x3’ perforated rubber mats that restaurants use in kitchens. They are super beefy and have little rubber “bristles” on the floor side to prevent slipping. I plan on joining three or four of these mats with heavy zip ties to make a flexible runway into the water for entering and exiting. This should help keep damage to the boat and my body to a minimum?
After a couple of hours this is where I am at. I need a few more pipe connectors which I will have to get on the mainland. But I think this is going to work. I am making the end with the skeg box quite beefy. Thinking about running a smaller diameter pipe inside that cross white section pipe (in the front of the photo), figuring I could buy a cheap Craigslist kart just for the wheels. The pipe within a pipe will be come a working axle.
This will take some experimentation and revision I am sure. I hope the wheels do most of the work, but this sled should be good protection in bad roll overs on the rocks. I want to get it all dialed in with the poly Dagger before trying it with my Romany which is in great shape. The weight is great. It will easily be stored beneath the kayak rack I also made under the house…
I like your approach using simple items from big box DIY store. Good also to see your Japanese style pull saw as they really zing through stuff.

I have a couple of these saws. They are awesome…
Gorgeous location. If you want to impress your neighbors here’s another option.
I’d like to see the video Peter-CA posted scored with something like Vivaldi… might alter the mood a bit.
It’s a difficult issue for sure - and would be nice to have a few solutions for differing situations.
Probably the first step is to have a kayak [or two!] that can take a little beating or is not too precious like a plastic boat. Maybe smaller rather than larger.
With that in mind, I’ve often thought that something like a 6’ [2m] long mat of chainlink fence [maybe plastic covered] might smooth out the bumps a bit and provide a surface that is less likely to damage a hull too much. A wider one might help the slippery areas if could be held in place if your shore is not exposed to weather and waves.
An alternative for killer shores might be a plastic cylinder that you push your kayak into and is rolled up rocks somewhat by lines at each end [ie it’s parallel to the shore] that allows the cylinder to roll up and down to a somewhat controllable degree.
Another idea is to do the same thing with a cylinder of any construction that is then pulled/slid up the rocks - if it is steep enough to slide back down that is!
For camping and reaching areas that are also difficult, the problem is even more severe, but some of the potential campsite locations are so exquisite that it’s worth considering how to get up to them. Pool noodles, small hpde mats, that fold-out paddlefloat by northwater, smaller yaks [conflicts with having to carry stuff, tho’], plastic yaks, or just beater yaks [while carrying a good repair kit] are possible solutions. It’s a great problem though and I’d like to hear more ideas.
[On sites that we’ve [BC Marine Trails] had more permission to intervene on, we’ve spent days moving heavy rock to make 6’ [2m] wide ‘boat runs’ in order to provide at least a semblance of small boat access. In well exposed sites, some maintenance work is required every year or so - it’s amazing how even large rock is shifted over a relatively shore period of time.]

I made more progress: made some cuts to each pipe for a better fit. I used outdoor screws through all the couplers instead of using pipe glue in case I want to refine the measurements again. I also adding more “ribs” cross sections. I can get more of the large flex tubing here but I need to be back on the mainland for more coupler joints. I have extra Thule straps to synch the boat into this sled. Like anything it will take some practice before I am comfortable using this thing on my own.
I have dragged both of my boats onto rocky shores with some minor scratches as a result. That is to be expected. But repeatedly dragging any boat down our rocks without some sort of protection on the way down and the way up (probably more hazardous?) is just going to ruin them in short order.
I do plan on taking my boats (via the car) to other put in spots throughout the San Juan’s, just for a change of scene. But I really hope this sled will give me a spontaneous “I wanna paddle now” option…
PhotoMax- I think your easiest way to get the kayaks over the rocks would be by using a section of an aluminum extension. It could be pinned to the rock with rebars and U-Bolt the rebars to the ladder.
Then buy or fabricate a “trolly” to ride on the ladder. You’d need to rig up wheels (like on a train) to ride along the ladder rails
Lastly, a winch to help raise and lower the trolly in control.
Paint everything PNW ROCK CAMO. The whole project could be done for about $300 in material and you’d be able to safely move the boats without damage.
Good luck with it.
Two words: Zip Line
(Or is it one?)
I really can’t install any kind of structure. Even if I could I prefer having the entire rocky area as natural as possible. The rock ledges are steep in some areas and very off camber in others. A small trolley would not work. Damage could happen at any section of the boat. I think my system is going to work. It will involve tweaking but there is no rush. The cool thing with this contraption is how little it weighs, which is great when I need to store it…
You could just wrap and strap the Dagger in tarp or astroturf or something like that and winch it down without all that extra gear. It will do just fine. The covering will take the minor scratches you might get. Maybe want something a little better (like your sled) for the NDK.
Another Neptune’s Ranger video for you:
https://youtu.be/tt7nR9dZTsM
Check out at about timestamp 3:20 through 3:35 and you will see a spot where the boats are lined down off of a cliff to a beach. No covering on them. The boats do just fine (though keep in mind these boats are treated harder on the water than off the water - and they do just fine with that also, so long as you accept scratches).
Looks like you might want to make a rope ladder to help you get up and down.
Peter’s comments remind me that I’m just thinking about fairly loaded boats. Hzll, with unloaded boats get plastic and just throw them over the edge! Barring humour, get a long line and push them over and down with a paddle or whatever as you make your own way down. An unloaded plastic boat can take a beating and after 3 or 4 years, get another. With a covering that doesn’t grab the rock edges, the timespan could even be longer. With the 30% gradient of fairly shelving rock that you have it’d be fine.
Hmmm… Could give new meaning to “launching your kayak”.
Trebuchet!

Now for getting it back up the rocks… You’re on your own.
The thing is that my photos really do not accurately show the steep ledges and off camber shelves of this rock system. Just walking down there takes some care! I am building this using the Dagger boat for now but I also want to deploy my more expensive Romany Surf as well. Like I mentioned the tide swings and resulting north-south currents impact any launch point location big time…
