Boat Trailer Info For Ballistix

[AndieMac]

Took some pics of one of the teflon/nylon slide trailers that I find very easy to use and maintain, making loading and unloading extremely simple. As with some multi-roller trailers, the planning strakes can get caught on the outer edge of a roller, making it sit crooked on the trailer.
This principle has been trialled for just over 20 years locally on sea ramps (effected by wave and swell activity) with great success.

For Ballistix...... If you have a V section attached to the aft end of your existing trailer, it will assist the boat to self centre and be guided onto the existing keel rollers.

More sections added will essentially convert the trailer to a full 'drive-on' version.

This process is cost effective and virtually maintainance free and can be constructed by anyone who is clever with metal.

The pic below is to show how the teflon/nylon is attached to the steel, in this case it is with SS rivets, but sometimes SS countersunk screws. This trailer is nearly 10 years old and always fully submerged in sea water. Boats rangeing from 26' to 30' are trailered on this particular tandem axle rig.

This big triaxle is built exactly the same with a 6 tonne load (up to 33 feet) limit, the boats are driven on, all the way to the winching post. This is a 315 Searay with twin V6 mercruisers.

Wow! what a trailer....!!!

....the one downside must be weight! I would think you would need that truck to pull it?

 

[STEVEDUNSTABLE]

as you said, wow what a trailer....the problom with that load n wieght is not the pulling but the STOPPING it!!!! a land rover could pull it but NOT LEAGALLY.... here in uk you have to have powered brakes over 3.5ton gross trailer wieght fitted to the trailer...and those systems get very upset at being dumped in salt water...........just for interest, i was witness to a 44ton polish truck with a snapped propshaft on the m1 in the middle lane. plod said wait for recovery etc...passerby in range rover used a chain and dragged it onto the hard shoulder...........yes it was fully loaded !!

A mate and I use the rig to transport boats on the weekends, his gear and my connections, find us enough occasional jobs. The prime mover is over-kill, but its part of his farm machinery anyway, and the clients like it.

Disc's fitted to all wheels with a 'Sensa-Brake' system (air over hydraulic), although hardly neccessary with the current arrangement. A little 7 tonner, 4WD at about 250 H.P. is all you need.

As far as making inexpensive modifications to basic trailers are concerned, I have seen successful outcomes from brackets made up from 2 inch galvanised tube encased with polyethylene pipe.

Even poly pipe (50mm or 2 inch), cut to length and fitted over the steel bracket that runs between the rollers on a multi-roller set-up, assists the boat to slide nicely down into a centred position. The poly also protects the keel and stem gelcoat from impact damage when driving on the trailer.
With a small hand saw, cut a 3/4 inch wide slit, full length of the already cut and measured (usually 280mm - 300mm, up to 12 inch) poly pipe. Spread and jam fit over the multi-roller bracket, then secure with 2 large cable ties. Cheap as chips, works well and lasts forever.

[AndieMac]

No worries Alt..... can we still put pics on the forum after that carry on recently?

Wow, that's a mighty trailer. I couldn't post a reply until tonight! I managed to get mine back on the trailer after a lot of trying...will post a full one over the next couple days. Thanks for the pictures!
