Slung Sand turns

AudereEng - 21-5-2014 at 06:34 PM

3shot posted a nice video (the 2nd one) on the JIBE forum - thread South tower run - where he showed how they buggy with cross beach runs.
He was running from the bluff toward the water and back with downwind skidding turns.
He commented that he Slung sand everywhere :thumbup: :cool:

I almost always getting wind across the beach due to bluffs on the Oregon coast - his video is how I normally buggy...

I thought he was literal with the "slug sand" comment - he later noted that it was more of a phrase.

Looking at his video closely the JIBE beach sand seems very different than my beach sand.

I often have an issue where after I turn in 1 area for a while (about 25 turns) sand starts getting tossed (slung) up in the air off my wheels and I run through the raining sand pellets on the other side of the down wind skidding turns.

Below are some turn marks from today (from the bluff side - the slower speed turn) created using a 3m kite (4 would have been the perfect size) using midi tires

The JIBE beach is also very flat - my beach is a little more like a wash board (not bad today) away from the waters edge.

I think both of these issues might be caused by some clay in the sand?

Thanks to a recommendation from csa_deadon (thanks) I buggy at Ona Beach State Park just S of Newport Oregon some days N or S of the creek depending on the wind direction, tide and where the creek is - it's location changes a lot

So
Anyone else have raining sand during down wind turns?
How common are cross vs. on/off shore winds on your buggy beach?
How flat is your sand?
How long are your runs between turns?

Thanks for the comment Aud :thumbup:. I will be honest. I've been to a lot of beaches from MD to FL and never saw sand so hard and flat as Jekyll. A buggy's dream. It is literally like dusted concrete.
Jekyll also has pockets of those washboards too. They change daily.

When I'm able to get to jibe next time, I will run my disc wheels. They should be perfect for the hard packed sand.

I didn't meet the guy or remember his name, but there was someone out at JIBE on some snake skins. I bet he could have blown the doors off of the rest of us if he opened it up and put the hammer down.

Just my sand observations...

I think it's a combination of both the size of the individual grains of sand as well as what might be mixed with it. JI has just pure ultra fine grains of sand and when they're wetted, it turns rock hard... Awesome stuff to ride on.

One island north on Saint Simons Island, there is roughly the same sand. When I stepped off the stairs to the beach from the rental we were in last week it was the same stuff, just dry, super fine almost like sugar. However, we were on the north end of the island very close to the tidal creeks and marshes that divide SSI from Sea Island, so as you approach the water, the sand contained some silt and mud from the creeks. This made it practically like mud in some spots, but just squishy sand in others. As you crossed the creek (or made your way around it) and got out onto the sandbar approaching the surf, it had less debris from the creek and was more and more like the JI sand. I had trouble riding on this beach because there were kind of pockets of really good JI style hard pack, and other pockets of squishy stuff. One day it rained all morning and the entire sandbar was hard packed and the wind was cranked.... I very much wanted to ride that day, but couldn't.

All the way north to the northernmost coastal GA on Tybee Island the sand is WAY different. The grains are way larger. They almost looked like meteors in comparison. Closer to the surf the hardpack was nice, but typical of most beaches, the soft stuff was really soft. I even noticed in one spot the sand LOOKED like hard pack, but almost behaved like snow with a thin layer of ice on top. As you stepped, it gave way and made a big deep footprint. That was not a good spot to ride. I seem to remember a similar "rain" of sand on that beach.

Nice video Phree' !

Around here it seems that exposure to pounding waves is what we lack ?

As soon as you drive down the West coast and get down below Vancouver island everything changes.

I agree that the sand type plays a big part in the puzzle but it seems we have no real hard pack since we aren't exposed to the surf.

I want like crazy to get to Jekyll and see but expect the hard pack is due to the surf situation as well as sand ? Pesky little things like islands off shore can really change a beach !

Can anybody compare the sand at St. Augustine beach to Jekyll ?

BeamerBob - 22-5-2014 at 02:42 PM

It's very similar. Those are my top 2 beaches to buggy on. I would give a slight edge to Jekyll but it is awesome riding at Anastasia State Park.

soliver - 22-5-2014 at 02:45 PM

I really want to get down to St Augustine.

How's the campground there at Anastasia State park?

nice! windyheap!

most of the sand beaches north of Jax have same powdery sand...the mouth of SAV river on TYBEE North definitely more coarse and thats where the rhodes dig deep with heavy action on beach just like JAX. but just north on Dafuskie, HHI, fripp, edisto....all way up to myrtle all have fine powder. the river sand in most of GA is more coarse and packed with clay!

and the weirdest element, is at night your tracks and the spray on the sand glow.


PHREERIDER - 22-5-2014 at 03:12 PM

oh yeah, and the grey color is from all the detritus washed out from behind the islands that gives it the low tide smell!
