Building a super new boat trailer, but on the cheap!

This is his current project. I've tried to tell him, but he's convinced it'll be a viable tender.

Reckon it'd make it to France?

Might have more chance than Jeepster!

Perhaps they could go together ?

Perhaps YOU should go back and read all the patronising and insulting comments thrown my way, even AFTER I proved Simon did not have a clue what he was talking about, because his MITcalc model was all wrong and did not reflect the actual loadings on my trailer, as my MITcalc model did.

It doesn't take MITcalc to see that thing is under engineered! The results from the calcs are only as good as the data put in. Use your common sense.

I can imagine how you might feel having been bombarded with these replies, but people were trying to be helpful in the first place. It was only when you blatantly refused to accept anybody else's view point and claimed you knew you were 100% right, when people started to loose paitence with you. There is a certain etiquette to communicating and putting your point across over a forum, and accusing people of being stupid isn't it.

My trailer uses exectly the same materials and has the same capacity as the Indespension Roller Coaster 1.3HE...If its good enough for them, its good enough for me!

Your longitudinals are substantially longer in relation to your overall trailer length than Indespension's are. I can only imagine on that basis that your swing beams are positioned further apart as well, resulting in a lower capacity to maintain zero deflection, when compared with the Indespension trailer.

Look what happens when you overload

Aha - the flaw here is clearly the lack of lightening holes...

At least it would be easy to trim its feet

Gotta love this thread

This Yank also appreciates that the original American trailer was sized and built right for the boat!

It's a British boat though-another muppet stuck an illegal (in the UK) American trailer under it at some point

The Inde 1.3HE trailer is meant for heavy engined (HE) boats. It's a 'development' of the original Roller Coaster 1 from the 1990s which had an 870kg GVW - same frame and roller assemblies, but a heavier rated axle (1100kg). The majority of the boat's weight would be carried on the single bunk of rollers, relatively close to the axle, with a pair of roller supports and a keel roller carrying a lot less weight forward of the axle.

Glad to see the muppets got exported as well


I don't know much about the original trailer, max gross trailer weight over here is 3,000lbs (1360 kg) unless braked. I doubt a 17ft boat with a 80hp engine exceeded that, so seems about right. There's really no way that boat can be trailered at <750kgs so the OP could have saved himself a whole lotta sweat and steel by just getting a better tow vehicle.

And thats just what I would like to do but I dont have any money in the bank right now and selling my current car could take quite a while, so its unlikely the boat will get much use this year.

That sounds good news

You could always start making & selling trailers, that should bring a few bob in. You've proved you know what you're doing & should now have the confidence to go forward. Just make sure that you get the type approval & CE marking sorted out & Bobs your uncle. Oh & make sure you get plenty of product liability insurance, simples for a man of your capability

Hi guys...Just wanted to give you an update on my current circumstances. I have been working full time for several months now so I am no longer in any financial difficulties.
I finally used the trailer I built to launch my boat and I have to say it was just as easy to use as I hoped it would be. I launched my boat single handed and the wheels didn't even get wet! It it was recovered with me holding the bow of the boat straight on to the centreline of the trailer against the running tide on the Thames and then it was winched on by a woman who had never even been near a boat trailer before! It tows like a dream, the caravan axle suspension giving the boat a very smooth ride and the brakes work perfectly.
Also I swapped my little Mazda 2 1.4 TDS for something with more towing capacity, a Vauxhall Zafira 2.0 DTI, which I found on Swapz. It was a straight swap and no money changed hands! Next I managed to find a used Witter towbar for it going cheap on ebay and once I had it fitted I was ready to roll.
The final addition was to swap the 13" steel caravan wheels for 14" five spoke Renault Clio alloys. (a perfect fit on my Knott axle BTW!) I bought three of them from a bloke on ebay for £40. I got three so that I could have a spare.
So all is well here, except in the trying to find myself a good woman department but that's only a matter of time.

Welcome back!

Did you drill those holes, or just go with the bigger tow car?

Out of curiosuity, if you didn't get the wheels wet I assume it was a helluva steep slip? My Roller trailer if I try to do a "dry wheels" launch or recovery puts a fair old bend on the chassis beams when the whole weight of the boat is supported by the rear rollers - I reckon form the dimentsions yiou quoted mine are roughly twice as deep as yours - and my wee boat only weighs 420KG full of fuel.....

[Max...]

This has put me right off any thoughts of modding a trailer to use with a 75kg SIB...

What a topic!



I was all set for an early night and then I come across all 16 pages of this unputdownable Ribnet classic.

Welcome back Jeepster! It's been a while, but we often think about you
