First off the year of your 18 will be the last two digits in serial number on the transom (back) of your hulls,this will help with what model you have .
If the hulls have wings(a framed seat that extends outboard on each hull)it could be a magnum or SX ,otherwise it looks like a standard h18 to me. The chrome triangular piece with the hole that is anchored to the croobar is the deadeye and the end point of your mainsheet.Once your mainsheet is threaded through the blocks and the clamcleats you thread the end of the rope through the swivel cleat (also mounted to cross bar)then through the traveler car fairlead and finally through the deadeye and knot the end of the rope.Usually when I put my 18 on the trl I untie end of rope at deadeye and
pull the traveler to the starboard end of traveler track where it will slide out.That way I can leave my block assy.attached to the boom intact,put it in a small sail bag to protect it.Saves time when setting up.Rudder kickup is adjustable with screw.Get ahold of a setup manual if you cant find on I can fax you a copy of mine.
