Extending my trailer hitch

Hello all,

I have had HELL with my trailer, as I have posted previously on the forum. I have a TomCat and it sits real high on the trailer making each launch and recovery a challenge. I received a PM from another member about a product called Extend-A-Hitch. I ordered it from the manufacturer's website www.extendahitch.com

He assured me that his 9 ft version could handle my 6000+ lbs of boat. Installation was pretty straight forward, although the bottom mounting bolts almost couldn't be installed in their pre-drilled postion because of the need for the extend a hitch to have enough clearance from the trailer's hitch to slide in and out. I barely squeaked by with that, the bolts couldn't even go 1/8" lower.
You NEVER tow with this hitch, it's only for launching and recovery. The receiver on the extension is 2" and the receiver on the trailer is 2 5/16", so a ball change is required before launching. I haven't found a 2" 5/16 receiver yet that I could bolt up to the extension.
Launching from a rough ramp is scary. The extension flexes up and down, but hasn't failed us yet. This is helping our launch and recovery. I need to come up with some quick snap on safety cables in case the day ever comes when the hitch gives way. Also important to note that a 9 ft hitch extension only gave us about 6 ft. more tongue after installation. I posted a couple photos in my album if you're interested.

John S-

I don't see any weight limit specifications upon a quick scan of the manufacturer's website.

Perhaps you need to contact them and see whether you're within the limits for which the Extend-a-Hitch was designed. Talk to their technical representative. AGAIN. Tell him/her your concerns.

What I'd do if I were in your situation, would be to get a slightly smaller box section of steel that would fit within/inside the existing box section to reinforce it.

A few bolts at each end, carefully placed back within the double tubed section, should increase the strength and reduce the bend.

It won't, however, increase the weight/strength limits posed by the attachment bolts or hitch itself.

Who recommended the hitch to you? Do they have the same concerns/experiences?

Let us know how it works out!

Joe.

Well,

I went back and did a little research. The member who recommended it goes by "Melon". I haven't discussed any of my concerns with him, but if he doesn't reply to this thread, I'll see if I can PM him to get him to post something on it.

The manufacturer- Basically it's one guy, maybe two at the most, probably working out of a garage, no tech rep there. I really don't think they know exactly what it can handle.

I don't think a large company would even tackle a project like this because of the possible liability. (ie Bubba decides to tow with it, rather than just launch)

I agree that I need to beef this thing up though. I can go with higher rated bolts, I also thought about adding some U-Bolts to the box section that the hitch slides thru.

I'm interested in the idea of adding a smaller chunk of steel into the main extension, I'll start doing some research on where to find that. The only problem is that every time I beef it up, I'm adding tongue weight and the extension already weighs 96lbs.

We have launched with it at least 5 times and have had much better results using it than not. A smooth boat launch surface gives no concerns, but we have a potholed 10" drop, awful launch in Whittier, AK that is down right scary without an extension. (highest launch fee in the area of course)

I guess it's time for me to start taking a bunch of measurements and go shopping. Unfortunately the boat is in AK right now and I'm in TX working.

John S-

Too bad it's in Alaska and you're in Texas. You could get the dimensions from the guys that build it and go shopping in Texas, where it would be less expensive.

Then again, I doubt they'd let you get on a plane with a 9 foot steel box section under your arm as carry-on luggage, and the alternative, shipping, would run the cost back up to Alaska sized proportions.

Wonder how many folks commute/work between the two largest states? (Maybe quite a few within the oil business!)

Sea Wolf,

Usually the prices in AK near big cities aren't too bad. Often the extra you pay in TX on sales tax is about the same as the amount they add on to merchandise in AK to cover shipping. In Anchorage, at least, there is NO sales tax. It close to evens it out.

To answer your question, although I fly for an airline, on my commute back and forth the planes have a large number of oil field workers who go back and forth working on the North Slope (Prudhoe Bay) and Texas. Most of them work two weeks on and two weeks off.

I'm going to PM Melon right now and ask him if he is interested in commenting on this thread.

I can't help you with your tongue extender but it got me thinking about a different solution to your problem. It could fail misserably but might be worth some consideration.

First off you would probably need to replace the wheel on the wheel jack to something that would roll easier on a boat ramp. Secondly you could mount a manual or electric boat winch on the tongue of the trailer pointed toward the tow vehicle. Once you back the boat in you would attach the cable from the winch to the truck. Then lower the wheel jack down. In theory you could release the tongue from the ball and slowly let the trailer roll further into the water using the winch. Anyway this is a hair brained idea from a non-engineer so try it at your own risk Laughing

flapbreaker,
Interesting idea and appreciate the advice, but.....we still have to recover the boat when its time to go. The trailer really needs to be attached to something steady in order to get proper alignment, trailer postioning etc. This extend-a-hitch is working

I just want to see it beefier and easier and faster to use. Every launch and recovery requires chalking the trailer tires, disconnecting the boat, and changing hitches and balls on the truck.

Yes! We're very popular at the launch.

Thanks,
John

I just sold my Tom Cat but I'll tell you what I did. I agree load and launch was always an adventure. I had a standard 2" hitch with the 2- 5/16" ball. First I bought a 19" Extend a Hitch from Cabelas. Then I had a friend make a 36 -38" extention that I used instead. I kept the wheel down on the trailer when retreiveing the boat. Once retrieved, I jacked up the trailer and replaced the extension with the normal ball etc.. If that makes sense.

The "Extend-A-Hitch" is not a new concept. Dump trucks use it all the time. If the trailer were designed from the get go to work that way it would be a piece of cake to make it so that you flipped a switch that would lock up the brakes and you could then release a pin. Pull forward and the pin pops into the longer toungue lock and then release the brakes on the trailer. Once the boat was retrieved you would reverse the process.

This of course would require something like a brake lock out relay (working to lock the brakes on) or electric brakes on the trailer. And it would certainly be something you would do on level ground!

Good concept but in my opinion it is too light duty to be launching a Tomcat on rough terrain. A 3/16” x 3.5” tube stretched out 9’ is not heavy enough for a boat the size of a Tomcat.

John S · Posted: Wed Oct 04, 2006 2:42 am Post subject:

Zydcomo, just so I got this straight, you kept the wheel down on the trailer tongue to offer some additional support? I like the concept of midway support, but a couple of our launches would rip that plastic wheel right off, I think. I wish I had a photo of this launch ramp in Whittier, AK. You really wouldn't believe it.

Oldgrowth, if this is not enough, what is? and how is the load capacity of a 3/16" x 3.5 tube determined?

I'm not sure but I think if this system were to give it would be at the mounting bracket to the trailer and not the tube. Only time and launching experiences will tell. I hope I don't find out.

My favorite idea so far has been adding a tube inside the extension to strengthen it. Next I think I will add U-bolts to the mounting bracket. Then probably assuring all bolts are the highest strength available. Finally I saw a 2 5/16 hitch available at a trailer accessory store for $50, it would have to be drilled to fit my extension, but this would keep me from changing balls.

I have hydraulic surge brakes, so I don't see any other way to change over hitches without chalking the tires. We DON'T keep the trailer lights connected when we launch.

Thanks for the ideas,
John

I can understand your problem with the EZ Loader Trailer eating up the gelcoat. We had the same problem on Cygnet, our TC24. Most of the damage was caused by the whimpy EZ Loader guide ons. The boat was easily blown of center on loading. I remodeled the trailer, and beefed up the side guides, and built a center guide-on. Look in the Discovery album, then the Cygnet sub-album for pix. This allowed an always perfect alighment of the boat over the trailer when loading. The new TC255 has this center guide-on, on the EZ Loader Trailer ( EZ Loader sent thier people to take pix of my trailer). Also the new trailer has the slick material on the forward part of the bunks. The TC255 is much easier to launch and load, than the TC24. If you are able to modify your trailer to assure proper alignment of the boat, I think the gelcoat issues will be reduced.

Brent,

Good to hear from a fellow EZ-loader sufferer. I was actually looking thru your album earlier today and asked you a few questions from a different post.

It was interesting to see that when you took delivery of your tc24 it had side guides only. Every other trailer of that era seemed to come with some sort of center guide on. You defintiely built a beefy center guide. What was the piece running cross wise made out of? Did you use layers of plywood or something else? I'm going to post a photo of my center tunnel. I think Confused

my guide ons are suffiicient, but maybe not. I added the plastic slicks to my front bunks last week and that seems to help. My bottom paint is so messed up from the trailer that I can't tell now if the new slicks are helping or not. The previous owner only took the boat out of the water once a year with the trailer.

I was amazed to see that your boat had NO apparent damage at all from your trailer on the forward pontoon area. ALL other TC24's I've seen have marks on them in this area.

Please look at my photo album, if you have any other advice on how to make this trailer work, I'm all ears. Do you think I need side guides???
I think side guides would take the trailer over 8' 6"

Thanks,
John

John S-

I once had a retractable keel sailboat that was on a trailer with a built in extendable tongue.

The trailer has to be designed with a large tube running down the center of it with the extendable tongue inside it.

Pins placed in holes that match up between the two tubes control the extension.

The tires can be chalked or the wheel jack used to allow the changing of the length of the extension.

Is there room to modify your trailer this way?

How about an extendable tongue controlled by a long jack screw powered by a 12 volt starter motor?

Joe.

Very interesting concept--but I also wonder about the tongue weight. For the TC 255, I am looking at about 800 lbs (not weighed). My thought was more to the effect of two small lightweight wheels (such as 8" rim trailer wheels/pneumatic tires) with a total capacity of 500 to 900 lbs each, with an aluminum I beam--the weight mostly on the I beam's wheels, right under the hitch (2 5/16 ball)and the beam mostly to guide the boat--rigid connection from the ball to the coupler. Backing would be a bit of a challange, but not more than a double trailer at worse.

The other issue is that the extend a tongue adds tongue weight to the trailer. If you had wheels, as I noted above, (Or Gleason makes 5/8" axel wheelbarrow wheels which have 550 lb capacity each--have to had a three leg support for the axel, but these are light and cheap) which could be put under the extend a hitch--just in back of the coupler--and take the weight there, it might resolve the weight on the extension issue. The wheels could be carried in the truck, and then the hitch jack raise the hitch up and the wheels put under, and bolted in place for launch. (We use a foot plate, I don't trust trailer wheels at this weight, but one oculd use an attatchement for the 8" wheels with a second trailer jack, and have a fitting for the wheels which fit into the foot plate tubing--just another option.
