No, it's 1b, but here's 1c:

In Response To: looks like cart 1a (mike allen)

: looks like cart 1a, but with the intersections pinned. try it without first,
: by using the webbing, i'm not sure it's necessary to do both. and way
: quicker and easier to fix if problems.

actually looks like 1b,(the full diag bracing)

and alternative along the lines of cart compaction discussions a few weeks ago would use tubes instead of wood. If its true that moment connections at the leg base are strong enough, forget the quadruple diagonal bracing. But i'd reinforce the bottome 1inch of the legs anyway w/ some epoxy fill before drilling for the axle.

so the idea would be to make the frontward legs out of 1/8in or 1/4in larger tube sections than the rearward, and on disassembly threading the smaller inside the larger, w/ the longitudinal tiny section inside those. for a super minimal cart that doesn't get major pulls, the longitudinal section could be replace w/ a just a pc of line, but its so minor i'd do it anyway.

to increase moment capabilities of the lower leg sections, consider sqeezing them a bit so they are wider at the axle. on the axle the rearward would go inside the forward.

the connection detail could be one of two: 1/an inside out analog of detail 1a where the webbing goes thru a tight ring and then around the tube or 2/simply a wrap around the tube going from the inside to the out so no hull damage. the longit member could thread thru holes in the leg tops to stop the webbing from sliding or just a pin.

if the yak is severely curved in plan, a cool cool possibility would be to mount the wheels BETWEEN the two legs to (almost) eliminate the moment torque in the axle(really minor anyway). you'd have to play w/ spacers a bit(prob not hard).

the advantage and the reason for these long leg carts is that you don't have to stoop like gorilla man to pull the yak and/or you don't have to keep scraping the stern as you go along the trail. they're as strong or as flimsy as a truss. it only depends on the tension or compression capabilities of the individual members you choose and if you choose wrong you can readily fix the simple ones in the field.

with these tube ones, i can't help thinking about paddleshafts and ferrules making the cart. stupid, i guess, but someone's gotta be.
