Usually up here beach lunching involves a freshly speared baldy or coral trout.....:)  

horrible but your worst problem is going to be once you get off the corrugations. You have to go up a steep hill thats got BIG deep potholes one after the other so i found my four wheeler just bounced badly in and out of one pothole after the other, tried going slower to stop it but sand very soft in holes and got boggy even with tyres down to 20. On the way in we got delayed for ages by 3 trailers that had shit themselves going up the hill, then all the traffic backs up behind cause track is to narrow to pass. Most guys like myself will try help you but theres always at least one arsehole that starts up about the situation (thats what happened when i was there a couple of pissed fuck heads started carrying on at people why they would even attempt to bring a trailer into shelter bay cause of how bad the track is) we didnt beach launch but from what i could see the beach is not steep and sand felt hard enough for a tinny i think that would be fine. Hope it goes well for you cause shelter bay is awesome sounds like your prepared for any shit with the trailers cheers dave

 You will be fine I used to drag a 6m boat fully loaded in there with an old hilux.. the corrugations can get bad just don't try and go to fast that's when problems happen. Go slow have a beer and relax.. the first hill is the only problem but with tin ya you will be fine worst case scenario you get bogged and snatched up.. beach launching will be easy with a tinny there are some soft camps and if it is to soft go speak to another camp and launch and retrieve there 

 Thanks for the input fellas. Will take it steady steady, rather the drive take another hour than spend the week with busted gear. Biggest worry is cracking welds or wearing flat spots in the tinny hulls but thinking I'll put some rubber strips down on the trailer slides to try and dampen vibrations.

We did the trip in mid june although I drove the boat from and back to Denham so I didnt see the track myself. 1 x car towed in a jet ski the other 2 weren't towing.

The guys said the corrugations were pretty bad and there was one spot where there was an unexpected rut or bump which got the car/trailer air bourne, snapping the tie down straps but luckly did not damage the trailer or ski.

It could be a good call to get one of the cars which isnt towing to go ahead and let you know over the radio where that bump/rut is if its not been fixed up since.

Shelter bay was an easy beach launch with the ski.

Sounds like you are taking adequate spare parts, when I went through In Jan the road through Carrang station was horrible so let your trailer tyres down to cushion the ride and go a bit slower nothings worse than breakage. After the causeway the corrugations get worse so do as above.

The first hill as others have said is usually the worst with big holes at times where others have been stuck, send the car that isn't towing up first it may need to pull you up, there is no room to get around or take alternate tracks for most of it. drop your tyre pressure down to at least 15psi, I usually go to 12 even without a trailer. Low range only go as fast as you have to for momentum because you are going to bounce heaps, max tracks could be handy if stuck on hill

Other tips, keep as much weight out of your trailer as you can, strap tinny down well. Only take what you need and less weight is the key, water, booze and fuel in that order. Time your trip so you are driving the track in daylight and if you have a breakdown/get stuck can see what's going on with a few hours of light to spare. From overlander to Steep its around 3 hours not towing so allow a couple extra

The beach launch there is a little soft depending on the spot but with small boats and a couple of cars shouldn't be an issue, consider leaving your boat in the water, a couple of star pickets work as a mooring system coupled with the boat anchor

 I think tyre pressure is the key. At the first little causeway crossing, let all your tyres down to about 20-22 lbs to take the hit out of the corrugations. When you get to the main causeway at the bottom of the first hill, take them down to 15 - 16lbs as was said. Keep up the momentum but no need to go crazy. When i towed my tinny in, the trailer had a 40mm round axel so i used good hose clamps and clamped a 50mm x 50mm piece of angle iron to the front of it to take the hits from high sand lump between the wheel tracks. I did see a guy once that bent his axel when it hit said lump. Sounds like you have got everything plus maybe more than you need. I think as long as you do all the correct prep work before you leave, then you shouldn't need to take so many spares. Maybe throw in a small portable 12v welder incase. Haha. Enjoy and be safe, it is a great place.

 Great info. Will be taking all your advise on board, especially the star picket mooring and axel bash plate! Thanks again and here's hoping the weather plays the game for us! Fish pics to come :)

 Dont be afraid to drop those pressures....I have happily gone down to 10 psi just need to re inflate before you go to crazy on hard stuff

for the resident bullshark that cruises up and down close to the beach there, he's HUGE and used to boats and people comes right in close for a look and probably a feed if he catches you enjoy and post up some pics when you can

 just my opinion but tyre pressure is key. 20psi is generally ok in average sand conditions but why risk it when you can go down to 12-13psi which makes all the difference. Also just as important to take the pressure down in the trailer tyres otherwise the trailer will become a plow. this will also increase comfort on the corrugations. no need to go too fast.

 Line your trailers with old carpet or any type of rubber mat. This will make a huge difference on the stuff in the trailer.

Always have large amounts of cable ties, they are priceless sometimes, we take some EXTRA large as well.

 Plenty of good info, Ive towed in there before and as above tyre pressure is the key..... Most dont but going down low like 12-15 makes all the difference between getting stuck and not.

other than the first hill the track in is no worries

Enjoy

 Bloke dropped in to the roadhouse yesterday looking for a set of wheel bearings on his way on

home from Steep point and was nearly going to keep going until I pointed out that if he didn't fix it now he would soon be up for new axle as well. He had never done one before so it was time to help a fisho out. What a prick of a job, no lip showing on the shoulder of both big and small cones to get a drift on to and we don't have a welder to put a line on the shrink it enough to get it out so grind the point off a cold chisel and persist. Took an hour and a half to do the one wheel, something that would usually take 20-25 minutes, but all good and he was on his way'

Bet he does them next time he heads in there

 Due to heavy rain yesterday /last night

 Yep thats the second 50+mm of rain they've had in the past couple of months...

The only issue with going low low with tyre pressures is peeling a tyre off the rim on the front when turning sharply so ensure to get some air in after the bad spots...

I'm sure you are onto it but be careful when snatching, obviously never snatch off the tow ball etc!!
