Permanent Beach Trailer, instead of dock or pier?

[Flightfollowing]

I recently bought a somewhat remote beach front lot in Kachemak Bay Alaska, and want to be able to load and unload my Mac26X easily to shore. Most lots in the immediate area use a Mooring, and dingy's to shore, or has some piers and a platform, or perhaps hires a landing craft for big loads. This depends upon the shoreline of the lots, either beach or cliff or hybrid. Note that Kachemak Bay regularly has 28 foot tides, making this process considerably more complicated than normal. Some other nearby bays use docks, but docks with a 28ft tide range and a 10 degree slope neccessitate a very very long dock, with lots of maintenance and expense for such a dock, and likely removal every winter. Note that not much beach exists beyond high tide, pretty skinny and the shore is sloped and fairly rugged, undeveloped and no vehicles, roads or anything of that nature.
I want to put a trailer on the beach and use a winch to pull the trailer up and down the beach, so that I can dry dock the boat all the way up the beach near easy access regardless of the state of tide. I have never seen this done before and wondered if anyone else has seen this being done and had any references about it. Or could point out what I might be overlooking in this plan? The beach is about a 10 degree slope, and fairly smooth but with the occaisional rock and a very few boulders that I'm pretty sure I can avoid.
I imagine that I might have a clothesline loop of rope/cable from shore to mooring, attached to trailer, and upon arrival, pull trailer down the beach into the water, motor mac onto trailer, and then winch the trailer and boat up the beach above high tide to a standard parking spot from where it can be easily loaded and unloaded. Departure is reverse, lower trailer and boat down beach into water, launch, then pull clothsline to put empty trailer back up beyond high tide on beach. Does this make sense? What am I not taking into consideration? Why haven't I seen this done before regularly?
Any trailer used for this will need to be extremely corrosion resistant, and likely would need to be able to be pulled from both directions to avoid swapping ends going up and down beach. The trailer may never get rinsed with fresh water, and just live right above the surf zone.
Alternatively, the trailer could be made to float, and be tied off at the mooring. Upon arrival, just drive the mac onto the trailer/dolly, and then drive the combo onto the beach, then winch it up the beach. A floating dolly would probably become completely encrusted with marine life and seaweed and kelp, creating problems if left floating all the time. Pictures below show the lot at high and low tides.
Any observations?

I don't think you're too far off base. I saw some similar setups in the San Juan Islands. Sorry I didn't take any pictures , but I'm sure there's something out there.

Clever idea.

Maybe draw from this for ideas

Probably make something from wood so it won't corrode. I would think without a freshwater rinse, even aluminum would be a problem. Or maybe not if there were no steel parts.

Gee wiz, that seems like a nice place for a boat house:

Great Link Russ, that does give me lots of ideas.
Their are lots of piers and a few boat houses, but my budget is minimal to begin.
these are the neighbors:

Will they let you put anything in the water? What about a railway type track rather than worry about how to get wheels over and around rocks etc

I don't actually know, but no one has any ramps or rails. Other coves have some docks, but also not ramps or rails. One would have to contend with ramps or rails getting covered, contaminated, or buried with shifting gravel from wave and tide movement. Also, a rail or ramp would have to be VERY long just like a dock given 28 foot tidal variation at 10 degree slope, like 200 ft or so. Plus undoubtedly some would complain and I would be "that guy' with the rails being an eyesore and impediment to access, as people do travel the beach to get around at lower tides. Thus my preference for a zero impact solution to the public beach zone.
I think the beachlauncher concept so far seems to be the most practical solution for all tide access. You can obviously see from pics that every pier built on the cove doesn't work at the lower tides, and when it does you still have to look down 5, 10, even 15 feet to your boat below you from your pier. The beachlauncher themselves are EXPENSIVE, the ones I see on their website are over $20k just for used jet ski models. I have just started to see one of these: https://www.sealegsrecreational.com/ which is a similar concept to the beachlauncher.





I am designing a winch towed beach dolly a bit inspired by the beachlauncher in my mind, and thanks to all for the input and advice.

It needs to be extremely corrosion resistant. (the beachlauncher is galvanized but they say that has a built in freshwater jet rinse system to contend with corrosion). Ideally it could be usable by different boats of similar or smaller size to a mac, so that I am not only limited to my mac every-time. It needs to be steerable to some degree, to avoid boulders.
I am thinking of using something like a capstain winch mounted on the dolly

That would run a loop of rope from the front of the dolly, to a pulley on shore, and back to this winch on the dolly and then back out to a mooring pulley offshore, and finally back to the rear of the dolly. Saltwater rope would be hard on the winch, but that is life.

I think you have the right idea,

The cheapest way to go would be a simple steel box frame with wheels at each corner and saddle bunks inside for the boat to float over.

Just hook your winch up to something strong on shore and the other end of the cable connected to the steel box frame with wheels.



Put a tow rope with a float on it for the back of that steel frame so you can pull it from shore down into the water from your boat. Also have tie ropes coming off the sides of the box frame with floats on them so you can see where the frame is when it's underwater.

Once the frame is under water float your boat between the side floats and over the frame and connect the side float tie lines to your boat.



Then just let the winch haul the frame back to shore dragging the boat with it - as the frame gets to shallow water it will settle up under the boat and the boat will rest on the bunks.



So when the boat is on shore do you need to hide it?? Can you put the winch inside a boat house so the boat is hidden and protected when it's on shore?

Is it like the TV show "Life Below Zero" that we all watch over here in California?? Do all you guys have big beards with icicles on them??

You are correct, Alaska state law requires large shaggy beards for anyone involved in reality TV, set in Alaska.

I wish I could draw as nicely as yourself BOAT! thanks for the ideas and suggestions.
I also started planning a beach mounted winch, but I don't have a remote control and didn't have solutions for free spooling it, so I am thinking more along the lines below, with a rope loop between beach and water, and the trailer in the middle.




My thinking goes like this: upon arrival, one pulls up close to beach below trailer and boat hooks the rope loop attached to back of trailer, cleats it off, and reverses boat to pull trailer down beach. The castering nose wheel(s) rotate and the trailer goes into water. Release rope loop, drive onto trailer bunks up against a winch stop at front of trailer, just like a normal trailer, and winch into front of trailer. then step onto raised trailer platform, boat hook the middle of the rope loop, loop it around capstain winch attached to platform, and winch everything up the beach. Some steering would be available with a tiller on the castering trailer nosewheel to avoid any rocks (although one would probably want to periodically patrol the beach and remove stray large rocks). once to top of beach, tie off trailer and all done.
To exit, one would reverse the process and use winch to pull trailer down beach with rope loop on capstain winch, steering towards mooring line. Once deep enough, drop loops off winch, pull away from trailer, then boat hook the rope loop again, cleat it, and reverse boat pulling trailer back up beach.
That is the theory.

I got a freebie ride on the largest sealeg craft they have made legs were over $100k Australian. As we launched on the maiden passenger trip we entered the water, you could feel the boat float off the wheels, the engines wouldn't start, a 6ft plus wave hit us and drenched the first four rows of passengers, lots of yelling for them all to move to the stern, we were nosing into each wave and being pushed more broadside with each wave, we were in big risk of being broached and rolling, the other boat rushed out and towed us to sea, lots of joking talk about oh dear we got wet, only the boaters knew how close we got.......

Whenever I launch into salt water I bring a garden sprayer filled w/ fresh to rinse down the wheels / brakes after put in and after take out. Flush the engine and rinse the entire trailer at home.
