Re: How do you jack up a trailer with the boat on it?
Put cinder blocks under the axle, then let out enough air to take the weight off the tires.<br /><br />Might want to make sure your portable compressor works before you do this.
Put the trailer-tire-changing jack you carry with you while travelling under the axle(s), crank it up in the air, and put a pair of jackstands under the axle(s). If you have a weak jack, do one side at a time so you don't exceed its capacity.<br /><br />If you don't carry a jack that's capable of lifting the axle of your trailer for a roadside tire change, this is the perfect time to discover the problem, go buy one, and practice with it.
Or. Another viable Option is. <br /><br />Jack,+ Block the trailer Frame. <br /><br />That'll also take the weight off the Springs. <br /><br />And. <br />It can be done with the Tongue Jack. <br /><br />Just Lower the tongue jack as Low as it'll Go. <br />Block the rear of the trailer Frame. <br />Now. Crank the tongue jack Up, above level. <br />Block the tongue,+ Lower the jack till the Blocks are carring the weight.
As long as the wheels are off the ground, give them a spin every time you walk past them. Keeps the bearings from marking the races. more
Measure a distance of 6 inches on the face of the 2-by-6. Mark the distance and use a carpenter's square and pencil to draw a line across the face of the 2-by-6. Use the circular saw to cut along the line. Repeat this process until you have one 6-inch-long piece of the 2-by-6 for each jack stand. here
If you use jack stands to lift your boat from its trailer to do bottom work, such as painting or fiberglass repairs, you can use automotive jack stands -- with one important difference. Automotive jack stands, when used under a car, won't slide apart because the bottom of the car is flat. Automotive jack stands used under a boat can slide apart if the bottom of the boat isn't flat, and can lead to unpleasant consequences. The answer is to tie the jack stands together in pairs.
1/2-inch wood screws, 1 1/2 inches in length
Measure the width of your boat across the stern -- or beam -- with the measuring tape. Use the bolt cutter to cut a length of chain equal in length to half of the beam of your boat.
Set one piece of 2-by-6 on the top of each jack stand and use your screwdriver to drive 1/2-inch wood screws through the holes in the face of the jack stand.
"The stands should balance the boat to keep it level athwartships. The boat’s weight should be borne by the blocking. Do not use the stands to support the weight of the boat unless the stand is designed for this purpose. Some boats require that the weight of the boat be supported on the chine. Use supports designed for this load.
ABYC Standard TY-28 addresses the topic of jack stands and their placement in detail. [links]
The proper number of jack stands supporting a boat depends on a number of conditions. This boat has its mast removed, which reduces windage, and the stands are on asphalt. more
Answer: Great question. In fact there is an industry standard that addresses this matter, and it was recently updated in July of 2014. ABYC Standard TY-28, which is actually a technical information report vs. a “standard," provides guidance for boat lifting and storage. It is the only document I am aware of here in the US that addresses this matter. [links]
"Additional attention to stands may be required during freeze/thaw cycles, before, during, and after storms, and on soft ground. On soft ground, extra, rigid pads, such as plywood, may be required under the stand(s) to prevent them from sinking into the ground.”
My next boat was a custom 18' Shadow weighing 700 lbs and also equipped with a 2.4 carb Bridgeport. This is the point where driving became interesting. I did fish a little back in those days, so I rigged the boat as most of your boats are rigged, i.e., 2 trolling batteries, 1 cranking battery, the internal trim pump for the 2.4 and all my fishing gear scattered throughout the boat.
While crossing wakes, try to hit them straight on, trim down and let the "V" of the boat work for you. While cornering, also trim down and lose some speed. Going fast is fun only if you can do it safely, without putting anyone else at harm!
Always wear your lifejacket and please, hook the kill switch up. In my opinion, a boat that is capable of walking NEEDS a foot throttle and tilt/trim on the wheel, so you will hever have to drive it with just one hand! Be safe. [links]
Prop selection can also have a great effect on control due to transom lift, steering torque and water holding capability. In general, a 4 blade is better for all around performance, but in my opinion a 3 blade is a better choice for new owners/drivers due to the lack of transom lift. To put it simply, the more boat in the water, the less chine there will be. The negative is that speed will be less also. The whole basis for chine is that the hull is lifting to the point that it has to be balanced on the pad and lifting strakes; this only occurs as the hull reaches it maximum potential. The idea that Ranger, Champion or other well respected heavy performance hulls are beyond chining is just not so. These hulls, given the maximum setup to achieve their fullest potential will chine also. more
