Re: Tandem Axle Trailer FLOATS!! What can I do to sink it?

Well, I saw a set of 2 grader tires and wheels, along with he pumpkin and axle housing floating down the Mississippi River... does that count? LOL

V

:eek:, but you gotta ask yourself were is the rest of the grader?????

Re: Tandem Axle Trailer FLOATS!! What can I do to sink it?

I thought I replied last night but it didn't post.. Here are the pics of the boat on the trailer. I don't think this is the right trailer for my boat. The bunks are 2"x6" 's and they stick out way past the end of the trailer. I think I need a longer trailer and you can see how long and flat the keel is under the boat so it takes a deep launch to get the bow floating up off the trailer.

No, that trailer is way too short. In the short term, I would definitley want to have bunks that reached the transom but with such a long distance between the bunk and its mounting point, not sure if it would really provide enough support. If that boat has been sitting on that trailer for awhile, I wouldn't be surprised if it is developing a hook in the hull.

I can't imagine you have enough toungue weight either.

Well theres your floatation problem, lots of wood products and air in the PVC pipes!!

Thats not a trailer, thats a raft with wheels!!!

Re: Tandem Axle Trailer FLOATS!! What can I do to sink it?

I filled the pipes with sand and capped the bottom. I thought that trailer looked short. I can move the winch post forward about a foot and a half or so, and maybe adjust the axles and move them backwards on the trailer. I looked at the bunks and they are kinda rotted. Does any treated lumber work or does it need something special? I towed it to Charleston SC from Naples FL and it pulled just fine. I have towed it back and forth Charleston SC and Charlotte NC several times and again it tow's well. I think the tongue weight is OK but would moving the winch post forward and the axles backwards help me much or do I need to be looking for a new trailer??

Dude, you need to find about four more feet of trailer behind the axles. And am I cross-eyed, or is the forward tire in the 3rd picture toed in at the top real bad? And in the 4th pic the back tire is tucked up into the fender? Maybe the way it's sitting, I hope.....

Man, seriously, you need a longer trailer. The bunks on that trailer were extended atleast two to three feet. It shouldn't be that way. It looks pretty dangerous having all that weight hanging that far back. I would be looking for a new trailer.

Re: Tandem Axle Trailer FLOATS!! What can I do to sink it?

Front port side tire is flat, sorry.. That's why the other tires are weird looking...

What is an Ideal trailer length I should be looking for?

Re: Tandem Axle Trailer FLOATS!! What can I do to sink it?

a good rule of thumb is to have the trailer at least 110% of the length of the boat.... IE 20' boat = 22' or more trailer....

BTW I still stand by the possibility of safely adding 'crete to a trailer BUT after seeing this the problem is a tiny trailer with huge bunks.... You need a LOT more trailer

That tire threw my sight off as well.

I have seen the floating trailer thing before though I have not owned one, and most all were float on aluminum trailers. I think the problem is two fold and one is the combo of light trailer with too much flotation/wood and the other is the need for the trailer to be further into the water and the fact that most go well beyond where they need to.

There was a ramp not far from a place I used to fish for eel when I was a kid that saw all kinds of action, and was really fun to watch all the goof ups and boats falling off trailers into the road etc (actually the action is even better now as the ramp sees more use, but I dont get there too often any more) but while there a few years back after watching a guy trying to overcome the floating problem alone we came up with an easy fix. and it was just to not back in as far so it did not float and then after getting the boat as far up as practical then attach the winch cable and slowing back down while getting a bystander or friend to winch the boat onto the bunks till it was fully up etc. The ramp is a solid surface and has deep water so it is a little easier than some. Still it is surprising just how far you can winch a smaller boat onto a float on trailer. Not as easy as a roller but does work. Just be careful with any slippery ramps and how far you back down etc.

I have done some interesting (ok a few were a bit stupid as well) things with trailering, but that was always at slow speed and short runs for the most part. Not that pulling this set up is the same, but it would benefit everything involved if the weight of the boat was more centrally supported on the trailer. This is especially true for longer hauls or higher speeds.

Some thoughts before you get a larger trailer, or even if you decide not to etc.

Move everything as far forward as practical. I know some AL trailers do not allow too much movement of the post, but gain as much as you can. I would see how far you can get and how changing the axle positions would effect the weight distribution before making any drastic changes there, but it does look like you could go a couple feet back without too much concern and may even want further back to better center things.

One thing just on stopping floating is to replace the side rails used for centering with some sort of solid plastic (star board comes to mind) as that will reduce float while adding some weight, and since you see problems with the actual support wood on the bottom I would just replace it and see if it helps. I think it has to help as green wood is wetter anyhow.

I have a friend who borrows a roller trailer set up for 25-26ft to haul and launch his 30ft baja. It hangs off much more than yours, pulls and works just fine, but and this is a big but lol he is going 2 miles not interstate. I have even used a neighbors roller he has set up for his 24 for my 26/28 (I still have to list it both ways cause I hate the confusion of hull vs overall length lol) and it works fine no matter if I move the front post up the 1-1/2ft it can be moved. It fits a little better when moved, but doesn't need to be etc. I think yours looks worse than it actually may be due to wood rails going beyond the end of the AL rails of the trailer frame (something that the rollers do on most roller trailers I have seen). Depending on the design that may not actually be a problem, but still I feel it should be up another foot or two on the trailer for long distance hauling.

So get rid of all the flotation, move everything up far as you can, don't be afraid to winch a little on retrieval if needed, and post back how it works out as I am really curious what you find.

That trailer is flat out too small for your boat.

If you are interested in selling it drop me a PM.

Re: Tandem Axle Trailer FLOATS!! What can I do to sink it?

simple solution nobody suggested.... add more air to the tires! At 70 degrees and 50 psi, air weighs 0.330 pounds per cubic foot. (air weighs 0.075 pounds uncompressed at 70 degrees)

So all you have to do is pump those tires up to around 1500 psi or so and it should sink! (or launch the trailer to the moon, so be a little careful!)

:D

(and no, i'm not serious.... It would take way more than 1500 PSI to add enough air mass to sink it.)

The purpose of having an aluminum trailer is to "save towing weight" Don't sink the trailer, get a better winch.

Re: Tandem Axle Trailer FLOATS!! What can I do to sink it?

The "cleanest" way that I have seen to add weight was using pvc sched. 40 pipe, 3" diameter or more.
Then it was filled with concrete and capped off at each end.
Then u-bolted on top of the cross members inside the frame rails.
Does not rust, does not fall apart, etc. and if needed you can slide them back and forth to balance the load.

Push your winch as far forward as you can.... and get aluminum bunks like mine and you should be able to keep your trailer if you're wanting too.

Also, mine does not float.

This sounds perfect!

The OP hasn't been back in awhile. He has other issues besides the floating trailer.

The easiest is actually to use an equilizing hitch. That forces the back of the trailer down.
