That's how keel boats do this....

i take it you will be putting in the first order then?

you should come down on the next cruise and see the trailer in action, i am sure james would be happy to knock up one for the scorp at a good price!

The most useful mod on my trailer is the custom made adjustable & removable beach launching wheels. It makes things much easier when towing out of the sea onto the beach with a rope.

I've considered my own design for some time, but I guess that getting around to actually building it ain't ever going to happen! Yep, I'd certainly consider talking to James about building one, but then I have my own ideas about how to design such a rig and would probaly want to do something a bit different!

I agree. It's a fantastic idea but I think sales would be very limited.
The bigger boats that would really benefit from it (and those who would see it as a smaller percentage of the overall purchase price) wouldn't be able to have one unless the trailer had assisted brakes and a dedicated tow vehicle.

The smaller <7m range would IMO baulk at paying a very significant part of the purchase price for the trailer.

one other item is a super strong ribbed trailer front jockey wheel that can take a ton of weight and have a pneumatic tyre so the trailer can be towed on a rope and not bother about the weight on the jockey

the two wheels mentioned are a good idea but not sure it would work on a heavy boat

Richard B · 03 July 2007, 00:09

But what if it could be accomplshed for a factor of 1.5x the price of a standard trailer?

its worth seeing it in action as a lot of thought has gone into it and it is a good idea, might be good to compare your ideas with what james has done to see if there are any benefits he could incorporate

must remember to order up some new bearings tomorrow am!!!!!!

having seen it in action, even if it was the same price as mine i would stick with mine....having launched in a lot of different places i am very happy with regular roller trailers.. ...however i can see it would appeal to a lot of folks and at the right price could be attractive to many folks

The thing is, I'm not talking about the same trailer, I have something different in mind that would work in a completely different way, but achieve the same objective of being a combination trailer where the road wheels are never submerged. Trailers are a very primitive piece of engineering, and there's a huge scope for designing something much, much better by starting with a clean sheet of paper rather than just attacking the current design piecemeal. James has made an excellent start at this, but I'm sure much, much more can be done.

That still buys a new hub/bearing set every year for 15 years.

Last year I thought seriously about starting a business building trailers like that. I spent a long time with blank sheets of paper,did most of the costings and so on but didn't go ahead (Believe me ,I've probably thought of every variation possible-right down to remote launching using hydraulic or air assisted rams).
I came to the conclusion that as an optional extra it'd work along with an existing business but the sales volume wouldn't be enough to sustain it as a sole design type. The drawbacks cut too many people out of the targetted sales window.

Yep, me too! That's why I'm still doing the day job!
It's just a great pity that companies like Indespension, Bramber, Snipe, De Graff, SBS and the rest continue to churn out the same old technology year after year. That's why I admire James for putting an idea like this into action.

A Ton, how is that useful?
Tow hitches on regular road vehicles only take 75-125 Kilos nose weight at best. Them there Vipermax’s must be real bow heavy.

The wheels in the earlier pictures do exactly what they were designed for with no probs, i.e. drag the boat and trailer up the beach.

one of these

http://www.towsure.com/product/13906...key_Wheel_48mm

so that if pulling up a hill, over stones, etc etc with a heavier boat then it will easily take the load and the fastener for securing the jockey wheel can take the strain as well due to the ribbed design.....had one on the previous trailer and they are great.

was thinking they take a ton but is around 500kg they can take

Richard B · 03 July 2007, 00:52

Errrr.... Chris me ole mate, I think you've missed Yoyo's point!

The problem is that 500kgs is downwards only - they bend pretty easily if you aren't careful.......

How about a nice walkway on the trailer, so one doesn't get their feet wet when recovering?

Andy

Mark has one of these on his trailer - very useful.
