PVC—I used 1.5” schedule 40. Quantity of ten in five foot length.
2” outside deck screws (100)
Fender washers (100)
Rubber garden hose 50ft light duty
Dock fender floats
D rings/anchors/cleats
Rope

I’ll add some more garden hose cross supports (ran out of screws and washers—used 100 so far)

Portable, removable, weighs about 30lbs

Works better than imagined
Designed so back third sinks so you could just drive up onto the ramp.

I’ll actually add a little more floatation all the way to the very back 1/4 just to have the perfect amount of front and middle bouyancy.

is that your backyard

good idea

Ha, no, I need to sweep some leaves out of the garage.

Friend’s dock.

Bien hombre

I priced out something commercially available, and cheap ones start at $999.
I knew I could make something serviceable for under $150 easy.
That’s $850 more dollars available for beers and fishing gear.
