Background:

I've been boating many summers with my family when I was younger, but never in my own boat. I've had my own small boat for under a year now. So I have pretty good operating experience, but owning -- not so much.

Shoreline and Launching:

We have a difficult shore-line with a broad tidal range and shallow approach, but would like to find a good way to easily launch and recover a small boat (16'). This is in a sheltered inlet, so the waves are never much bigger than a large lake (except when someone's 40' yacht or a tug boat cruises by). The tide goes out much too far to be able to launch/recover at low tide, but I'm fine with a solution that works from mid-tide and up.

I am renting this property, so do not need a solution that will last a decade (a few years is fine), but I don't want to rebuild every year.

Here is a photo of the shore line at to low tide:

At high(est) tide, the water comes up to the rock wrap on the right.

I've been looking at the ShoreDocker and Multinautic roller ramps, and think a 30 foot span (2 kits) might do the trick for me, but am looking for input and suggestions. I thought I would be able to find sets of roller-wheels cheaper than in these kits, but haven't found anything yet. I've drawn on the photo a "~30 foot" red line where I would build.

A alternative consideration would be a set of sturdy launching wheels for the aluminum boat. Many of the ones I found look like twigs and I'm worried would break. Beachmaster looked like the strongest/best built option. The main concern here would be preventing future boat upgrades (see below), and perhaps the brute force required for up-hill solo recovery. Thoughts?

The boat:

I currently have a 16' open aluminum Lund fishing boat with a 30hp Yamaha electric start and steering console. I would like to upgrade to something a little faster that is also more comfortable, smoother and more stable in the water, while still able to deal with the shallow approach. The target budget is under $10k (for a used boat). Our usage would be mostly leisure (just to get out on the water and cruise around the inlet), but also some light tubing/skiing and fishing (a few times a year). We are fair-weather boaters, and will avoid days that are really choppy.

I'm thinking of a small Seadoo Speedster jet boat, but have no direct experience with these. Given the type of ramp I'm looking at, my max is 2000lbs. I would also like it to be small enough to fit in the garage in off season; we have an empty spot, but no where else on the property suitable for storage. The 16' aluminum is there now with about a foot to spare.

Boat priorities (ordered):
  • Under 2000lbs (loaded)
  • Shallow draft
  • Smooth and stable as possible for a small boat (able to handle wakes from 40' yachts without stressing my wife)
  • Comfortable seating with space for 3 most of the time (and 4 in a pinch)
  • Light duty skiing / tubing (no pros here)
  • Fishing / crabbing (but no fancy equipment, outriggers, etc.)
  • Fit in garage (<= 17ft)

Thanks for reading. I really appreciate your input!

Re: Shore Ramp and Boat Recommendations for difficult tidal shore line

I agree; when you move up, a trailer is what you want. rollers and if you can find one, tilt, with a power winch. alway skeep the trailer axles above the water.
Can you drive in some pilings to help with mooring? Build a cat-walk pier?

Thanks for the suggestions. This steers me in a different direction. It may be difficult to get a permit for a pier or moorings, as I'm beside a protected wildlife area and they oppose shore development, but the trailer is do-able.

So with this approach, I'm trying to figure out how to do it solo. I think I'd need someone to help push/navigate the trailer, while someone else operated the winch from the top. I suppose an upgraded front wheel for the trailer is also required.

I could pull the loaded trailer up where the red canoe is currently stored to keep it out of the water.

Are there any tricks to keep the trailer from leaning backward while launching/recovering the boat? I've never trailer launched without a vehicle attached to brace it.

Re: Shore Ramp and Boat Recommendations for difficult tidal shore line

I as not suggesting trying to launch from a trailer that isn't attached to a vehicle, or a winch that isn't attached to the trailer. If you've ever had a boat pop off the ball in the launch/retreive process you know why. And sinking a trailer "all the way" in salt water is a bad idea, too.

You're moving up to a bigger boat and you can't plan to just handle it like another canoe.

Oh. I had misunderstood. There is no way for me to get a vehicle down here.

Would simply rearranging the rock/gravel constitute "development"?

I could get away with some rearranging.

Re: Shore Ramp and Boat Recommendations for difficult tidal shore line

We faced similar issues on the great lakes and "trying" to keep a boat on a ever changing coastline. In the end the lake wins, and without some costly permanent equipment, I would recommend using your local boat launch and scrap the idea of tracks/winches and wheels. Add the tide issue and the size of boat you're suggesting, there aren't really too many choices. We had a small track with a boat carriage that would roll the boat from the beach out into the water. It failed, it also blocked the beach for walking pedestrians creating a hazard. Any reason you can't just launch and retrieve daily and store your new bigger boat on the trailer?

Re: Shore Ramp and Boat Recommendations for difficult tidal shore line

At a friends cottage, we built a boat lift on wheels that used gravity to get two jet skis to the water down his bank, and an electric winch to the boat house to pull the rig up on shore. The battery had a cheap charger on it, and would only last 2 years, however it beat cranking

the wheels were nothing more than cement filled tires on steel rims with a welded hub, a plastic bushing and a piece of stainless pipe to ride on as an axle. they were held on with a bolt thru the end of the pipe. We put hub caps on them to cover the rust

The frame was galvanized pipe that we sprayed the welds with cold galvanizing compound, then painted the whole thing with bottom paint to make hosing the crud off easier with the pressure washer in the fall. We used pipe with PVC pipe over it for the boat to sit on, and standard 2x4's with outdoor carpet on the sides as a guide.

lunching was easy, let gravity take it to the water, then push a bit toward the end. unhook the bow and go. Retrieval was hook the bow, walk up to shore and winch the rig up.

The neighbor had a pair of cedar logs as a boat track and a trailer winch mounted to a tree to pull his 14' out of the water up on the bank

Re: Shore Ramp and Boat Recommendations for difficult tidal shore line

you could build a long sliding lift with a winch, or get a sand trialer for a kayak. it should hold a small tinny.

Re: Shore Ramp and Boat Recommendations for difficult tidal shore line

this may seem like overkill AND may not even be suitable depending on how soft the "ground'' is but near me a number of people keep old fergie etc tractors JUST for launching their boats of a sand ramp....no concrete...,

may not suit your situation though, just a thought

Re: Shore Ramp and Boat Recommendations for difficult tidal shore line

On lakes that allow boat houses up here (grandfathered in) they just have a set of "railroad" tracks that pull the boat on a cart up into the boathouse with an electric winch. You could do that on the shore as well

Re: Shore Ramp and Boat Recommendations for difficult tidal shore line

Thanks for all the great feedback!

Then as I said, you have all the native material in the world, all you need do is re-arrange it a bit.

After I build a ramp, I still need to figure out how to get the boat to water. I don't have a way to get a vehicle down here.

Thanks. I think that could work, but would worry about metal tracks rusting in salt water.

The roll-and-go ramp is alot like what I have been looking at from Shoredocker and Multinautic.

I'm still thinking something like this (or the one you mentioned) is the best approach. The wooden kits are about 1/4 the price of aluminum. In my mind, I get two kits for a 30 ft run (or find a place to buy the rollers, and make it myself).

Although I admit the trailer (without vehicle) idea had me intrigued.

At a friends cottage, we built a boat lift on wheels that used gravity to get two jet skis to the water down his bank, and an electric winch to the boat house to pull the rig up on shore.

I can see this working. Do you happen to have any pictures of this contraption?

Re: Shore Ramp and Boat Recommendations for difficult tidal shore line

Back to the idea of using a trailer (without vehicle). What if I put a pair of pneumatic swivel jacks or castors at the back end of the trailer, to help stabilize during launch?

You really only need some Wheelie Bars like on a drag race car.
You will not be moving at the time you are preventing the trailer doing a wheelie, so no wheels would be needed.
They would also keep the trailer from rolling as you launched and recovered.

Success!

I went with the trailer proposal. I picked up a cheap used trailer, and added a Tie Down Engineering Spare Tire Carrier to mount the front wheel.

With a little help from my brother, we built a ramp using pressure treated lumber over the steep section up the rock to a landing at the top. The hardest part was getting the trailer around the side of the house to the back, but we jigged the TDE spare tire carrier on a 90' angle and used it the wheel the trailer down on it's side.

I'm using a Dayton 14L040 115V AC winch to pull the boat up and lower it down the ramp. It's slow, smooth and steady in both directions. I mounted a bench roller to keep the winch cable off the rocks at the top of the steep section.

I've attached a few photos showing what it looks like bringing the boat in at about an hour from high tide.
