Boat Trailers

OK so all this talk of heavy boats on trailers with the associated risks is starting to worry me.

I am running a 685 Cruise Craft with twin 4 strokes on a 3t trailer. Problem is that with a full tank of fuel and a couple of full water bladders plus all the fishing gear and bits and pieces that we lug around I reckon I am very close to my legal limit. This is especially so when we do trips away to Carnarvon, Coral Bay etc with all the additional gear that goes into the boat. So questions are:

  • If I am running overweight and I am involved in a MV incident where towing may play a part, do I get any leeway legally ie do they allow say 10% over  or is it 3,000 or less = OK, 3,001kgs or more = not OK
  • exactly what is involved in upgrading the trailer from a legal limit of 3T to 3.5T
  • I guess I have to assume new axles, springs, hangers etc but can I retain existing hubs, calipers, rims etc
  • I am currently running ford slimline bearings in my hubs but I think these are too light and would prefer to go to a heavier bearing, does that mean new hubs and if I get new hubs does that mean new calipers as well.
  • Can I get to 3.5T with 14 inch alloys (standard Dunbier issue)
  • My trailer looks to be in reasonable condition but perhaps a couple of the cross members look a little tatty so if I am upgrading would probably change them over as well

Now having 10 thumbs and not being that technically minded I would be looking to have someone reliable do the work. Can anyone recommend anyone who can do the job from start to finish including the re-registering part ?

I would appreciate any feedback on the above and any recommendations for prospective people to do the work. I should add that I am SOR

cheers

hey Bruce, you don't say if

Sun, 2013-11-10 13:55

hey Bruce, you don't say if the trailer is Dunbier, only rims?
Your boat will be essentially the same as mine, allowing for 10 or 20kg on the outboards and a little on the trailer itself. Mine came in at 600kg trailer, and 2700kg with almost no fuel (50-100 litres).

First stop would be to speak to both Dunbier and/or Martins (take the trailer in there?).
While springs have ratings, generally they just look at the number of leafs and width (60mm?).
The rims should have a rating cast into them, but you can get 14" Ford pattern onto 3.5 tonne if you use loadsharing suspension (roller rocker etc rather than torsion/slipper). I have Mullins on mine and they are 1000kg each.
Have a look through this, and Ill chuck up some more info later if need be!

Hey Rob

It was mainly your post and Bodies post that started me worrying (thanks for that !) But need to get it fixed, as you say you have an identical boat at 2700kg on the trailer without fuel. Add 300l fuel and then the two fresh water bladders I carry plus gear and easy over 3T I reckon. Yep its a Dunbier trailer.

I've just been out and had another look at the suspension set up, the brake controller and the tyres so that I freshen up my thoughts on the general overall condition.

  • Rims are rated to 1,050kgs so they should be OK provided I get the right hubs ? 
  • The Carlisle brake controller is rated to 1,000psi, not sure if this is adequate to go to 3.5t rego ?
  • Longitudinals on the trailer are in good nick but maybe 3 of the crossmembers are scruffy. I would probably do all of them.
  • From what I can see the front of the front spring is bolted to a hanger, there is a rocker in the middle bolted to a hanger that the rear of the front spring and the front of the rear springs are bolted to and the rear of the rear spring is a slipper. Is this load sharing ? As I said I'm not mechanically minded ! If its not, will going to rocker rollers share the weight more evenly between the two axles. I ask this as there seems to be more weight on the front axle than the back axle.
  • Springs themselves are 40mm wide and 9 leaf

Given that the price of a new trailer is almost extortionate - $16k from Roadmaster, a refurb is going to be the way to go I think.

Cheers

bugger 16K, if you were going

Sun, 2013-11-10 15:58

bugger 16K, if you were going get new go for a Peterson at about $12K.
Sounds like load share. Id probably take the trailer into Martins, or ring them, they will be able to tell you but I see their 9 leafx45mm twin axle is only 2500kg.

45mm sq axles are max 1500kg per axle
The various bearings have their own max ratings.
Good resources are Martins Trailer parts website
Spinny Things on Ebay
Huntsman123 on Ebay

Lots of info there

Alternative as I said to Bodie, is go to Transtyle (or Trojan) and order complete torsion axles with brakes and everything then its just a bolt on job for maybe $4.5K complete with rims and tyres.
I suspect your brake unit wont be up to it either, all the ones I see are 1200 or 1600psi, 1000psi is normally only drums?
That's how Id go next time.

Bruce, if your looking at a new trailer, check out Ace trailers. A Mate of mine just puprchasied one and they will do a trade in for your trailer aswell. Mate of mine has a 24ft Carribean with twin donks. New Trailer was about 12k fully optioned with 2 lots of spares and 6 new rims and tyres. Good thing is, local too. And made of Ali.

Im going to order the Trojan torsion axles hopefully today from the same mob Ace trailers. They also do tralier mods, repairs and so on. I will be putting in 2 x 2.2tonna Torsion axles which were quoted at about $1,100 each which included axles, hubs, Bearings, disc's and callipers and galvanized. Basically just bolt onto the Chassis and done!

This will rate my trailer to 3.5T

Advantage is the torsions axles are lighter and you no longer need leaf springs which is one less moving part which rusts that needs replacing.

 

Hopefully have all the parts in the next week or so will post up some pics once done.

Mon, 2013-11-11 21:01

Crikey, $16k for a trailer.........I got a 3.5t MagicTilt ali trailer from the US for US$5,500 which was about A$5,200 at the time, great trailer, tows perfectly. Has bunks, not rollers, I will not go back to rollers now I have bunks, they are so much easier to float the boat onto.

 

Still, with exchange rate now and transport plus other costs (I needed it to sit my boat on), I guess costs would be well over A$10k.

 

Downside is US spec everything, so parts may be an issue??

If your looking for a new trailer give Terry a buz from Tezzas Trailers 0410 565 665. He built mine for around $12500. It's rated to 3.5t and set up for a ally boat but he builds them to order. Its built to last and is a dream to drive on.

Cheers for that Brendan. Looks like its all open channel as well. I may give him a ring. Meeting up with Guy from Ace Trailers on Thursday and then another local builder on Saturday. That should provide me with enough info to decide whether to refurb or buy new.

Just one out of the blue, would it be a problem if I went to an even heavier trailer say 4T ? I can only pull 3.5t with a cruiser but it shouldnt make a difference if the trailer is registered heavier so long as i dont go over 3.5T ?

I feel your pain and concern

Mon, 2013-11-18 14:40

Never had an issue with the boats I have owned, but trailors????.

Bloody had my fair few mishaps. So even though I have a current 5.4 Trailcraft Ali that came with a standard single axle, the first thing I did was add another. Then upgraded all the specs on the rims, calipers etc.

Probably overkill for what I have, but at least I know that if a tyre blows (happened) or I loose a rim (happened) the remaining axle will get me home. Poor old trailers just cop it. Everything in them gets drenched in salt.

Spend an age cleaning the boat, but the poor trailor gets minimal attention from me in the past. That is not the case now.

I am so bloody paranoid now after the mishaps that I probably spend more time and almost more coin looking after it.

It is due for a hub service again so more $$$ as I am like you, mostly 5 thumbs on each hand.

Had the trailor rated with the upgrade and is 2.5T, way over what I need for the Traily. But feel more confident with the security, plus can laod it to the hilt for trips, leaving the Cruiser free for the important stuff.

4T brings bigger issues

Mon, 2013-11-18 14:57

Ace Trailers built mine back in February this year...fantastic trailer.  Got 220mm ali I beam, 2.7ton axles, oversized hubs/bearings, walkway, 2 spare wheels with hubs/bearings, full keel and bunk rollers.  Really is overspecced to give me comfort.

However, anything registered over 3.5T requires a 75mm tow ball, and that was a step I didn't want to take so it's registered for 3.5T.

Ignore them

Mon, 2013-11-18 15:09

I dont think they have ever tried to price one up. $12,500 is fair/cheap.

The other way to go would be to bring one from the states...but then you have compatability issues down the track. Not a great problem, but just one more issue to have to worry about. Plus they are generally aluminium and "I" beam (less maintenance issues).

I reckon I spend more time keeping the trailer clean than the boat these days. Always easier to do when the trailer is new. Getting used trailers is a bloody nuisance. I reckon too many people overlook the quality of a trailer when buying a used boat. For me, having a good quality (newer) trailer is probably as important (if not more important) that the age/hours of the motor or the boat. Its not the be all and end all, but it can be a deciding factor.

Tue, 2013-11-19 09:59

Bruce, i just ordered the reaplcement axles, hubs, callipers and so on for mine from Transtyle trailers in Melbourne. Got the run around here from Ace trailers who didnt bother calling me back and Martins didnt stock torsions suitable for my weight requirements.

Ended up going for

2 x 2.5 Tonne Transtyle torsion galvanized axles

Galvanized 12" 6 Stud Land cruiser lazy hubs and 12" Ventilated Rotors with one spare Lazy hub.

Kodiak Stainless Callipers

6 x 6 stud Landcruiser Allow Rims and Tyres (With a load rating of 1,180 KG)

Full spare set of bearings

Stainless flexible hydroulic brake hose kit.

 

5k plus delivery.

 

Not a cheap exercise but wanted to really beef up the running gear, and this should do it.

Only thing Id have maybe done different is have SS discs and Dacro calipers-depending on how long your trailer sits unused.

Thought about the SS Discs, i have Darco discs now and they look fine after 5 years. to go SS was another $1,600 or there abouts.

Good thing is, it only takes 2 weeks to get them too!

Fri, 2014-01-10 18:19

"•If I am running overweight and I am involved in a MV incident where towing may play a part, do I get any leeway legally ie do they allow say 10% over or is it 3,000 or less = OK, 3,001kgs or more = not OK"

Insurance wise would be unlikely to be a problem if your just a tad over but well over (100kg or more) could be another scenario. Property damage cover possibly declined and if you seriously injure someone possibly facing recovery of cost of injury. If that were to happen I wouldn't be mentioning the water bladders - just standard load (but I didn't tell you that)...

Policing is a separate issue and would depend on the officer involved.
