4.7m (15ft) Boat Trailer
Introduction
This 4.7m boat trailer is a strong but lightweight trailer suitable for most boats between 13ft (3.95 meters) to 15ft (4.7 meters) long with a vee hull. With fully adjustable rear quad wobble rollers, an intermediate set of adjustable dual wobble rollers and keel rollers, this trailer will suit most alloy and fibre glass hulled boats. Launching and retrieving of your boat at the ramp, just got a whole lot easier and quicker!
Distance between the guards is 73" (1850mm) and overall length from the coupling to the rear quad rollers is just over 16' (5 meters).
The boat trailer plans include details of the winch post shown in the pictures above, and also two fully adjustable winch posts to adapt to different bow and winch eyelet setups.
The trailer is suitable for boats up to 1320lbs (600kgs) although if the tire and spring specifications are uprated, boats up to a maximum of 1760lbs (800kgs) can be towed.
Disc Brakes can be fitted if required but wider guards will need to be fitted to compensate for the additional room the braking hardware will take up.
Details are included for fabricating your own wobble roller arms and supports that will potentially save you hundreds of dollars. "Off the shelf" roller setups can be fitted in place if you are reluctant to build your own.
The trailer plans include details for preparing the trailer for galvanizing (a must for salt water boating).
