Float On Boat Trailer

I also would like to know how to set the bunks for the boat to rest on the trailer right thanks for all the help

The trailer, or at least the cradle section has to be completely submerged so the vessel can float on to it.

Bunks should be set to take an even part of the weight along their full length and should never have square ends. They must press against chines and/or strakes and must not bear on unbraced hull skin sections. They should extend beyond the transom not finish before it so the strongest part of the boat takes the load. Wineglass displacement hulls are very difficult to spread the load, but are probably the main type of boat that needs a float on/off trailer.

The keel is going to take the biggest proportion of thew load, but should not have all of it. It is nearly impossible to have too many rollers, but every roller must bear on a part of the hull that has a bulkhead or major frame member behind it. A combination of as many keel rollers as can be fitted, as many guide rollers as will do anything meaningful and at least one long chine bunk each side (my trailers have three each side, two full length for a total of six) will do some way to supporting your hull safely.

Bunks spread the load wonderfully, but rollers can have such a small contact area that they can have over 100 times the normal floating loading on the hull. Rollers must never be used for competition boats, or foam or balsa core or lightly built ply boats for this reason - they will quickly damage these hulls beyond repair. Alloy too must be supported on multiple bunks - not rollers except for the keel (and there you should have one every foot or so) unless you like a pattern of dents in the hull.

Edit - When towing any outboards should always be fully tilted so the engine weight is furtherest forward in from the transom, thus much less stress on the transom, and rear hull contact points.

I have a 14foot boat with a 50 hp motor - the motor is probably heavier than the boat, as I have to buy mudguards and wheels for my trailer and smaller mudguards are cheaper, what difference do smaller wheels make say 10" over 13" is the boat easier to launch with smaller wheels from a slipway, as the boat will float quicker, or will the back-end of the boat catch on the slipway floor if it is to steep?but if you have 13" wheels surely your car must have to get nearer the waters edge to float your boat off the trailer, as you can probably guessed I am new to boating and have never launched a boat yet, so any answers will be gratefully accepted, cheers

One of the boats I ran some years ago was a 16' Glastron with a 60 hp out board, the trailer was fitted with 13'' wheels the smaller wheels won't make launching easier. The problem with 10'' wheels is that trailer is often nose high unless you fit a drop plate on the tow hitch and then you have a problem with grounding the hitch. A nose high trailer is dangerous.
With regards to launching aways keep the trailer attached to the car either on the tow hitch or attached using a long length of rope between the car and trailer if its a difficult slipway that way you can keep the weight of the trailer under control, if you try to man handle the the trailer down the slip you stand a big chance of losing control and losing the trailer in the water (I've seen it happen a number of times and recovery is usually difficult), try to keep the wheel hubs out of the water particularly in salt water, if they get immersed in water they will need to stripped cleaned and re-greased very soon after, keep the winch wire attached until the boat is floating on launch and use the winch to draw the boat onto the trailer on recovery, to float it on means immersing the wheel hubs and that is bad, the rest is just practise.

Regard above comment. In the UK mudguards and lights, reflectors and number plate are a legal requirement.

Don't put it that deep.

If it is a float on/off type then it must be very lightly built!

Most conventional trailers don't get put in the water past the lower rim edge, as the bearings are safest kept out of the water.

A light trailer with large tyres will have a lot of displacement, so changing to light truck and/or narrower tyres may help if it is a real pain.

Our town is having a contest on who can create the best float. The catch is you have to decorate a boat not a trailer. We are using a pontoon boat. Please let me know any creative ideas you may have!

Have a bunch of people ice fishing with santa hats

make it into a big snow blower

How about a big bed on it with two kids sleeping and have everyone else dressed up as sugar plums and candy dancing around in their heads
