Step 1: Cut the pieces of lumber to the desired length – generally around 4-6 inches long. Both pieces should be cut to the same size. I know there are rubber alternatives, but looking on Transair they seem a little more expensive (not sure if they're cheaper elsewhere, but I'm not specifically looking at that). Now you’re ready to chisel out the !recesses. If you’re an experienced ‘wood butcher, you’ll have your own procedures. If not, here are some suggestions:

The example shown was made about 30 years ago of Honduras mahogany. For reasons of maintenance, oiled teak is preferable. Varnished wood simply wasn’t made for cradling heavy chunks of metal. Step 3:With a drill and proper bit, create a hole on each end of the second piece of lumber for your screws to attach to the first piece at an angle (about 20 degrees). They’re an effective load securing method when used correctly, but they can be damaged easily. Keeping straps in good condition Straps used in the UK usually have an STF of 350daN or lower. For some loads, you may need to use straps with an STF of 500daN or more to reduce the number of lashings required. Other information on the strap

The shank slot is easier insofar as its edges are parallel, more difficult in-sofar as there’s a longer slope to cut and smooth, But the procedure is the same as with the fluke recess. Drill a control hole; a 5/8″ bit produces a 5/8″ slot (which is good for anchors up to about 20 pounds.) Then proceed as before, carefully and patiently shaving down the sloped slot. Provided you have time inthe lift dropping the rudder out is fine. Providied the cradle is big enough to provide support as you take strain off the slings then you will be best putting the boat into this first so that she is fully settled with the weight on the keel before putting props in all round. There is a real risk of dammage if you put a prop in before all the load is off the hoist of the prop causing excessive pressurein a single spot. As said elsewhere you may well find that the boat pivots as the weight comes off. You will also need to ensure that the boat stays upright. If you havn't done this before please get somebody who has done a few to help. Once settled in the cradle a good number of props tied together as shown on the Saddler should be fine. Make sure that the props are positioned on strong areas of the hull. If you are determined to leave the mast up strip off all you can, frap rigging hard to prevent vibration and even consider wrapping a warm round and round the mast as a 'vortex shredder'. I personnally thing the right size cradle is the thing to get and take away a lot of trouble and worry. inspect any straps involved in a load shift incident - do not use them if they’re worn or damaged, even if the damage appears to be minor

Cut out the wood; then lay the an-chor on the two pieces and, lining up on the centerline, mark the positions of the crown, fluke, and shank recesses. direct - where one end of the lashing is attached to the load and the other end is attached to the vehicle or trailer Don't worry about the bow and stern props until the end just before the belts get dropped away from the hull. When securing a load in the middle of the load bed, or a load that is not very tall, you should either: Positive fit is a way of securing a load inside a trailer or vehicle body that’s strong enough to withstand the forces likely to be exerted on it during the journey, for example a vehicle or trailer constructed to the BS EN 12642 XL standard.The STF is the working tension in the strap created when the lashing is ratcheted down over the load. It’s only used to calculate the number of lashings needed in frictional lashing.

look for any signs of damage on the straps before using them - you must replace any straps that are significantly damaged You can keep your straps in good condition by using sleeves or protectors over corners and sharp or abrasive edges.They make a great addition to your toolbox for added safety measures when working on your vehicle, but they should also be used with other precautions in place. The same holds true if you need to apply de-icers or other treatments such as washer fluid or anti-freeze when temperatures drop below freezing.
