Hey Kev,

I had a trailer built it's 2.6mL X 1.4W X 850mmH i wanted the trailer to be light comes in at 250kg and "low" so not to create too much drag when towing it sits at boot height of our Aurion.
The trailer fits in 4 boards 5 sails masts booms etc and all the other gear i have since added some racks made from pvc in it to seperate the booms and masts from the sails.

Very common to see "Go-Kart" used as windsurfing trailers in NSW.
EBAY has them all the time...Just try and get one that is not too wide.
1.6m wide is plenty....Cheers and good luck

Hey Choc

Great design, I like the idea of just adding a few mods to a box trailer.

Is the lid easy to get off? What sort of dollars to build?

cheers mate

Made a mistake it's 1.8m wide not 1.4m, lid comes off easily total cost of the trailer was $2600, built by local Barmera engineering workshop.

KevKev,
There have been a lot of these thread here in the last year or so with all kinds of ideas. Have a search..

Choco - $2600? OUCH!!!
A secondhand tandem 8x5 is $500 - $1000 and the box part can be made for $300 (or if like me , you get all the square hollow section steel from the tip and sign sheeting for free from a signwriters so the box is about $50 (glue, rivets and paint) and you get a trailer from a relative with stuffed bushes and flat tyres for $30. Total cost about $400)..........



..it is a 8x4 so it is still the same wheel track width as the car - a lot easier to tow down 2 wheel rut type tracks into secret spots, and also as it is not wider than the car, and low, the fuel consuption is good. An 8x5 would be a different story.

Fits 3 waveboards, 8 sails, 3 masts, 3 booms and all the misc crap with ease.

I thought it was cheap, got a quote from Adelaide(for my design) and they wanted $2700 just for the trailer without no lid, regardless i'm happy with what i got

Funny how as a trailer owner i have previously felt like a nerd compared to the Van guys. Good to see other NERDS.

Here is mine. Just finished some mods yesterday after an idea seen in a Van at Sandy Point last weekend. Will make life easier.

It is a standard 6 x 4 with mods. I had the trailer glavanised to avoid rust. The lid is a add on alloy with 2 gas struts and lock (and a new one after breakage). The front box is separate which goes into the trailer V. All can be removed within 3-5 mins to allow for trailer use.

Cost- $850 trailer, $500 lid, $200 front = approx $1550...... it was good use of the 1st baby bonus as otherwise dogs, kids, = no gear.









The loft compartment for sails can take 4-5 sails up to 5.5m others need to go in base with gear.

The bars and the device to allow for removal and hinging of bars was idea i got off guy with an awesome van at sandy last week (sorry dont know your name) This enables the sales to lock in place and hinge down for easy access. His was made of alloy but mine just wood and routed out guide and holes. Screwed onto side with stainless as i cant weld..... well welding wood not good idea. These took maybe 20mins to make. Great addition

Everything is rust proof.

Anyway....it'll do till i get a VAN....and become cool.

Here,s mine. Still a work in progress

ahh the old trailer thread again!
heres mine at the moment.
inside is aprox 250kg of sailing gear
8 boards
13 masts
15 sails
9 booms
and assorted other crap
and room i amguessing for another 2 boards and couple of sails
the only limiting factor being the weight.

who needs 9 booms??

i would be fuzzing out the number plate with that much gear in there!

Every time that I read the title of this thread I think it is about a demo day of some sorts.

Whoops sorry forgot Pedro's kit

one of the key design points when building my trailer was to avoid a swinging door that had to be secured open in any way.i achived my goal by having the door hinge up then slide onto the top of the trailer in tracks.works well.

Ya still can't beat the ol' golf buggy & bike combo for cost effectiveness, I reckon...

Sorry I dont have photos, as I've sold the trailer.

I built it myself about 15 years ago and it lasted very well.

Overall length 10', width of box 3' height of box 2' with plastic mudgards over the mini (10") wheels on Indespension units. I tried to reduce the fittings I had to buy to a minimum. The front of the box was tapered in to about 4" at the nose and I could get 3 windsurf boards and a surfboard in, plus 6 sails 3 masts and 2 booms, with the boards in their board bags. I did find that the sails got worn by being piled on each other and shaken about in the trailer. It would take boards up to 275 cm.

2" square box section spine with 2" box section axle welded to it at 90 degrees on either side, and a 2" angle iron bottom frame for the box. I ground recesses to make the floor flush & welded the Indespension mounting plates to the underside of the ends of the box axle.
Its important to get the wheel position right so there is about 30 kg downforce on the ball hitch when loaded.
I used a matching 1" angle iron top frame, with 1" angle iron uprights and cross bracing. All the 1" angle iron was outside the aluminium panelling except at the roof, where I had a flat top so I could carry stuff on top if I wanted. I put slotted foam lengths on the 1" angle that jutted down inside. The sides and bottom were all flush inside and I used heavier 16 gauge aluminium on the top and bottom and rivetted the panels on.

I extended the 1" angle cross bracing at the bottom rear corners to mount the door, which was a rectangle of 1" angle panelled flush on the outside, and the sides extended down to mount the hinges, which were just 2 bolts through holes drilled in the 1" extensions of the angle iron.

At the top of the rear opening, I welded a bolt that jutted out through a hole drilled in the top centre of the door, and a padlock through a hole drilled in the bolt.

Its best to seal the ends of the box section when its built to reduce rusting inside.

AND HERE IT IS FINISHED FINALLY !!!!!..JUST AWAITING SOME QUALITY SEVERNE STICKERS TO ADORN THE SIDES...am pretty happy how it turned out allthough if i built another one i wouldnt make all the mistakes i made while building this one !!...now just gotta find the time to get out and use it all !!!!. Cheers to everyone who posted all those other trailer pics posted for some great ideas.

HI mrrt...I did see your trailer ( well one pic anyway) when i googled " windsurf gear trailers" in images...it is well done; pity i didnt find your webpage till now ;woulda saved me a few headaches i reckon !!!
Have u found anything you shoulda fitted but didnt....anything you thought woulda been handy when it was made but too late now...?

Cheers Kevin

What size hydraulic struts are you people's using? Length or even better Nm would be helpful.
