• What maintenance is required?  Regular maintenance is vital, especially when using the trailer in saltwater. SBS Trailers recommends a few basic home maintenance tasks and suggests using products like Prolan spray on vulnerable zinc-coated parts (like U-bolt threads and winch gear) as they are more susceptible to corrosion than the main galvanised chassis. An owner's manual is available from the manufacturer for more detailed information.
• How do I ensure proper boat support? The winch post and roller system are fully adjustable. The goal is for every roller to touch the hull, clear of any strakes, with the bow eye reaching the winch post for optimum support and tow characteristics.
