    It's pretty common to bog a 4X4 vehicle on a beach close to the water, and the tide can make a difficult recovery quite stressful. So in this video I get my car bogged next to the water, and talk through how I recover it...alone.
    Note: if you're looking for lots of fast action or excited people then don't bother watching, everyone else is doing that.

    something i learnt from experience use the largest tyre on the smallest rim that is possible this will allow you to decrease your pressures down to 5psi which has gotten me out of situations
    eg 265/75/16 on 7 inch rims .to get 285/75 16 you must use an 8 inch rim which now diminishes your bead pressure for low tyre pressures hence you roll the bead a lot easier talk to the
    tyre business about this when selecting tyres

  • @alexdevries7594
    @alexdevries7594 3 ปีที่แล้ว +6

    Hey Robert, thanks for the video! I completely agree with the tyre pressures points - thanks for providing the graphics of the different pressures. I’d love to hear your take on wider tyres and what effect they have on the footprint.
    I’ve never had much luck with heading straight up the beach like that - I’ve always used momentum to get the vehicle moving straight across or down the beach and then use that momentum to gain height up the beach.
    Whenever I stop, I make sure I’m pointing downhill so I have some momentum to get started again. If I’m doing a u-turn, I turn up the beach, reverse down and around, then forward straight across again. Making sure to keep momentum.

    • @L2SFBC
      @L2SFBC  3 ปีที่แล้ว +1

      Agree with all that and will demonstrate some of it....as for wide tyres, pointless. You get the same flotation with narrows, and there's less frontal area so less rolling resistance. The momentum-along-the-beach technique can work, but I didn't use it as it is risky - often you can slide downslope into water, and the turn up the beach can be difficult. I find it works best when the lower part of the beach is flatter.

We were on Padre Island or Mustang Island EVERY free minute.

    that's odd. In my experience the damp sand between the water and the high tide line is actually firmer than the loose dry sand up at the top of the beach. And you always want to stay on the firm sand just above the water for as much of the distance as you can then build up speed to jump up through the loose sand above the tide line and through whatever gap in the dunes you are using to access the beach.

    • @L2SFBC
      @L2SFBC  3 ปีที่แล้ว

      It can be firmer, but it can also be softer. Depends on the beach, and to some extent the tide. But getting bogged there runs a risk of being bogged and then waves get you. So what you describe is a valid technique, but it doesn't always work. Wouldn't have done in this situation.

    your sand has a much different character from the sand where I am. where I am, the key to getting back off the beach is to spend as much time as possible in the wet sand. the wet sand is compacted enough to hold the weight of the vehicle, while the dry sand will not compact. so a run along the wet, and then a gentle enough turn to get aimed at the exit without sacrificing momentum, and hit the dry going fast enough to get to the hardpan without losing all your momentum.

    • @L2SFBC
      @L2SFBC  3 ปีที่แล้ว

      That can work here too, but it's high risk so I don't recommend it. Reasons; possible splash of salt water, and wet sand can be softer as well as firmer. It is also possible that the sideangle is greater closer to the water. And if you do get stuck within the area where waves reach, then the waves will remove sand and sink you quite quickly! But every beach is different. Main this is to adapt your technique to the situation.

From what I’ve gathered: there’s a particular type of sand that people here refer to as “sugar sand” which is basically just mostly dry but still moist sand. The consistency is basically about 20-30% clumped sand to give it a sugar type look. That type of sand will get you in trouble quick as I know all too well.

      Interesting technique,and valid in not spinning your wheels,correct Tyre pressure and the back and forth motion applied. Best option thou is -1, don't create a new course,follow the existing track. On a reasonably sloped beach,the sand sometimes a meter closer to where your demonstration started can be very soft just on the ridge. The best technique is not to do a u turn ,but rather to angle up to the dry sand in a 30 to 45 degree approach, this is more reliable and keeps you away from the potentially softer sand on the ridge I mentioned.

    Do lockers have a use in sand/beach driving. Thanks again for all the time and effort you put into keeping me out of trouble.

    • @L2SFBC
      @L2SFBC  10 หลายเดือนก่อน

      The purpose of a cross-axle locker is to ensure that one wheel on an axle doesn't spin uselessly compared to the other. In sand, you typically have roughly equal amounts of traction on both wheels on an axle, unlike say rock where you are frequently balancing two wheels with a third having minimal weight on it and therefore traction. So, cross-axle lockers in sand don't help a great deal unless you have a situation where one wheel on an axle has more weight on it (traction) than the other. Even worse, a cross-axle locker will increase understeer and therefore drag of the tyres, requiring more steering lock for a given turn radius, and that extra drag could well see you bogged. What you do want to do is lock any centre diff in sand, but not cross-axle unless for example you're ascending sand dunes in a desert which have been dug out by people wheelspinning probably due to too low a gear and too high a tyre pressure. For sand, tyre pressures are critical - see my other video on why, and also my sand driving principles for use of momentum.

      @L2SFBC  3 ปีที่แล้ว +1

      Yes they would prevent wheelspin. However, they also restrict turning and create significant extra drag, and make sideslopes more difficult. So, while my Ranger does have a rear locker, I did not use it for that reason. Also, the weight on the wheels is about equal, so the locker wouldn't make that much of difference. Lockers in sand are most useful in the desert when ascending rutted dunes, not on beaches.

      No. They would be a bad idea. They would increase turning circle and create drag for no benefit. There is not really any difference in traction between the wheels, which is what lockers control. Yes, you do see a single wheel spin, but the small benefit from controlling that is outweighed by the inability of the wheels to turn at different speeds around the corners, which creates drag, as does the need to turn the steering wheels more to achieve a given turn radius.

    So... here's a question Atmospheric pressure at sea level is around 15 psi. How do you air down to 10 psi.

    • @L2SFBC
      @L2SFBC  9 หลายเดือนก่อน

      Question of the Day
      At sea level, the air pressure is around 1013.25 bar. It varies a bit depending on exactly how far you are above or below sea level, and also atmospheric conditions - you hear weatherpeople speak of highs and lows, and barometers dropping indicating approaching bad weather.
      Air has mass, although we don't really feel it. As it has mass, the earth's gravity attracts it. The air near the earth's surface has air above it, squashing it down. Imagine stacking 15 plates; the plate at the bottom would be carrying the other 14. Similar to air. So, the air nearest the earth's surface has the highest pressure. The further away you go from the earth's surface, the lower the pressure - this is the principle on which aircraft altimeters work, they precisely measure air pressure and read out your height above something, either the earth's surface or a given datum somewhere in the sky. There have been deaths when people get that wrong and aren't at the altitude they think they are. By the way, elevation is how high you are above sea level whilst on earth, altitude is how high above the earth you are (or another datum).
      Anyway, the standard air pressure at sea level is 1013.25 bar, or 14.7psi. Yet when we have 15psi in our tyres the tyres are not flat. How so?
      The gauge is calibrated to read 0 at 15psi, which is atmospheric pressure.
      As far as tyres are concerned what we want is an increase of pressure over atmospheric, so it makes sense to call atmospheric 0 and work from there.
      Now this raises all sorts of interesting questions, or interesting to me at least. In theory, tyre pressure gauges should be calibrated according to atmospheric pressure, just like aircraft altimeters - if you're going for a local flight, you'd twiddle a dial on your altimeter to set it to zero before you take off. For those driving in high elevations, same thing, ideally you should recalibrate your gauge. But then comes a complication. Tyre pressure is about relative pressure between tyre and atmosphere; so let's say you need 30psi at sea level. You operate at 4000m where the atmospheric pressure is much less. Should you still be using +30psi over atmospheric? I leave this as an exercise to the reader, and don't forget to factor in temperature, reduced tyre drag and cooling, and of course fractionally reduced gravity...

    i saw a ww2 movie where a group; had big British truck for a group of 4-6 who i north Africa were heading to Tobruk. at some point, they had to go up a sand pass and the truck refused to go. they pulled the plugs and used a hand crank to move the truck in reverse uphill almost imperceptly./ they explained the sand would hold together and support because of slow movement--any ideas on the science of this--or just a plot mover?

      Incredibly slow movement does work that way by avoiding wheelspin, but I can't see a hand crank being slow and smooth enough to work.

      ah ok I see that now. Yes hand cranking would work to move the vehicle. However, I'm not convinced there would be enough leverage to allow it to be moved up a steep, soft-sand incline. Also looks like they didn't let tyre pressures down. The basic premise is also questionable; if the engine overheats, let it cool down, then try again, maybe at night when it is cooler which helps 3 things - engine power, engine cooling, and denser sand. Or, drive up as far as you can go, then crank.

      @@L2SFBC tree anchor strengths? Oh interesting. As far as gear goes I don’t have too many sources for you. Out in the field we use adjustable hollow braid slings (Whoopi, loopi, deadeye) usually in a simple girth hitch or timber hitch configuration. Amsteel is very common and is rated for a lot. Tow straps and tree savers are perfectly fine but with slings it’s nice to be able to adjust the length to match the tree diameter or to create a really long neck for positioning the eye of the sling (the eye being the anchor point) anywhere you like. That way the winch line doesn’t rub on the surrounding objects. The biology of the tree itself doesn’t really matter too much compared to the local soil condition provided the strap is set low enough and the tree is healthy with no signs of decay, visible cavities or fresh dirt from the roots pushing the soil up from wind stress or water erosion. I will say that smooth bark trees like Eucalyptus, Sycamore, Himalayan birch, etc. can potentially run the risk of letting an anchor slip up the tree but it’s a pretty rare problem.
      You might want to add that anchor points on trees are often at a bad angle to the road. Sometimes I like to find 2 trees opposite of each other and run a line connecting them. Then using any good midline knot, or a prusik loop that can adjust, or even just a free floating pulley placed somewhere in the middle that allows you to get the right angle you need to get the pull going more in line with the road.

    • @7kyro
      @7kyro 3 ปีที่แล้ว +1

      Also on small trees, with questionable strength for holding an anchor, you can tie it off to another tree for added support, known as a dead man. A lot of the time it’s less about the gear and more about the limitation in anchor points and the angles the offer. You have to get creative sometimes. I’ve even cut a dead tree down so that it will land closer to the path and allow for a better anchor to rig off of. This can be used if you’re line is too short and you need an extra few feet to ideally secure it to an anchor.
