Re: guide posts or bunks
What you need depends on how you launch and retrieve. If you sink the trailer and float the boat all the way up you need bunks to support and centering guides to line the boat up. If you drive or winch up the boat, rollers would be added. <br /><br />I normally center the bow and drive/winch up on the rollers. Two of my trailers (for outboard boats) have bunks, centering guides and rollers. The third trailer is full float on with bunks only(for pontoon boat). The pontoon trailer is the least user friendly. The ideal trailer to me is a full roller tilt such as Easy Loader sells...but it gets costly replacing all the rollers.<br /><br />I'm in salt water...to keep corrosion down I use motorcycle chain lube (spray foaming type) on the roller pins, springs, axles, hubs and hardware. The rollers go before the mounting hardware even begins to show rust. It penetrates like thin oil, sticks like grease and doesn't come off for dozens of launchings. I also spray the galvanized trailer frames once a year with CRC "Heavy Duty Corrosion Inhibitor". It takes 4-5 cans per trailer but lasts a year and keeps the metal rust free. It has a very slight amber tint and is dry to the touch after a few minutes...great stuff.
