More of a trailer design challenge?

[rebar]

Hey folks.

Green river lake in wyoming does not have a concrete boat ramp. It has a nice gravel turn around that leads to a gravel shore. No mud.. I do know people unload/load 16 foot motor boat there, but they might carry them. My idea was to put my concept plywood barge on a tilt deck-over trailer so I wouldn't have to back into the water as far. AI calculates the weight at around 500 lbs and only drafts a few inch's, but this sounds sketch by myself. The angle of the tilt bed may not allow the barge to float before it hits ground or takes water.

Anyway, I can build the barge to fit a miners tent. Sorry, AI would not draw the tent I asked, but the bigger challenge will be the trailer and loading unloading, but a deck-over maybe to tall?? Will I have to narrow the barge to fit between the wheels for a better departure angle? Or design a slight V in the the hull to get it over the trailer wheels?

Thanks!

The easiest way to deal with that is with a trailer tongue extension. I prefer this sort, but you can make them any length you want. It's just installed at the ramp, not for roading.

That looks easy to control!

I'm not sure how far I would need to back in at Green Lake, actually.. Or any other primitive gravel ramp for that matter.

I better forget the deck-over tilt trailer idea, and build something narrow enough (74"?) to keep the boat between the trailer wheels and on top of the dropped torsion axle..

Also considering composite bc AI is telling me I could build it much lighter.

I'm looking at the XF-20 plans..

If you have a downward slope a decent jockey wheel can be used to back the trailer in on ropes or slings. Some trailers have an extension draw bar too for launching, similar to the link here.

Thanks..

I'm afraid the barge might be to heavy to unhitch from the truck, but the extension looks better than the first contraption..

I messed around looking at the XF20 and little brother the XFTS19, but I'm concerned there isn't enough buoyancy up front to support me, without a outboard on the back..

I also tried to talk google/gemini into drawing what I was thinking.. Gemini got close, but nowhere near perfect..

What is your objective? Are you looking to mostly drift down a river?

Yes, and also row in protected calm waters up to the second Green river lake in the Wind River Range. I need a stable platform to fish sleep and relax for a week, so the deck must shed rain water.

I was thinking the Jon20 plans from duckworks might work out.. But I would need to reduce free board to 16". And I'm wondering about raking the back to resemble the front. But it would be stupid not to include a mount for a 9.9 hp even though I cant use it on the upper green river lake. Also looking into a bit of rocker..

Stunning scenery!

If you rockered the stern of the Jon20 I'd recommend doing about half the front rocker as a compromise.
