have built my grass cart and tested it quite a bit this spring here in beautiful indiana.
soon as the frost was out of the ground we were running it. if anyone is familiar with the mid u.s. you know this is when the ground is the softest and muddiest. quite impressed with the 22x8 tires all around, has excellent floatation on the soft surface (doesn't leave any tracks or ruts), and beat the bigfoot tire weight by a pound. best part is no tire wear running on grass. cart dimensions are 60" wide by 70" long, monofork with 30 degree layover steering. first time out we hit 48 kph with a 4 meter windsurfer sail and finally hit 50 kph about a month later. are these respectable speeds for the surface involved? pretty crazy feeling on the rough surface, can't imagine going faster but definitely will be trying. best part is the power slide you get when gybing, love it.

Those speeds are very impressive for that kind of surface.

Any chance of some vids??

Does the sail sit on the pilot's chest when sheeted in? Looks very low
That said, certainly looks the part and obviously works well. Nice job

I have to say , that yacht is simply beautiful, so very speedway, i reckon Vic will be drooling
If your cracking 50kph on that grass you should be very happy indeed. top work,

That is one of the coolest land yachts i have seen. Great work keep it up and good sailing. (very Nascar looking)

That is one great build and Paul it does look very speedway.(one of my home builds)

Cheers
Vic

Wow you have really achieved something there Good work!!!

Nice space frame seat! Is it possible to add a skirt around the nose and floor to stop ones foot from touching the ground ? Not nice when that happens. The windsurfer boom setup is fantastic for low end grunt, which is perfect for short circuit grass off road sailing. This one needs a better name than "grass cart" ? More like NasKart

Haven't finalized how the nose of the craft will be finished yet, something will be added. On wet grass we get a little side slip if a strong gust hits you, but feel that is what makes it so much fun. about like a go kart or four wheeler when the back end kicks out. gybing on wet grass is the best!! already carrying good speed and when the sail picks up the power, back end comes out , little countersteer, feel it accelerate, head to the next turn, then repeat over and over.
They work good on asphalt also and last way longer than a barrow tire, have gone through at least a dozen barrow tires in the last year ($15-20 a pop). $30 for these and they have lasted all spring, ride smooth, and carry excellent speed with traction thru the turns. very happy i tried them.

front atv tires for sand. ams whipsnake. if i lived near a beach would maybe try one with the center blade, trimmed down a touch.

couple short videos

definitely feel this is a direction the sport could grow. more of the masses live near a grass field rather than a dry lake or salt flat. food for thought.
