    If you are still having trouble advancing the bolt remove the back bar from the boat and try the bolt in it. Look for metal chips or dirt particles inside the bar which could be hindering the bolt's progress.

    10. The four outboard bolt assemblies are identical. To install, first slip the bolt through the outer end of the corner casting and down through the rail of the boat. Place the stainless steel channel over the bolt's exposed section which is under the rail. Spin the nylock nut on the bolt but do not tighten the bolt down at this time.

  • Page 10 See Figure 14. WARNING The diamond wire adjustment not only affects boat performance but also affects the mast structural integrity. If the diamond wires are loose or broken the mast will be permanently distorted or could fail completely.

    Always wear a life jacket when boating. BALANCING THE BOAT When sailing, sit on the upwind side of the boat (wind on your back) just in front of the tiller, facing the sail. Balance your weight further outboard as the boat begins to tip or heal over with the wind in the sails.

  • Page 29: Turning

    TURNING To tack or turn the boat into and across the wind to the opposite direction (also known as "coming about"), follow the points of sail guide illustration and take the boat to the close hauled point of sail. This is when you are nearly 35 degrees from sailing straight into the wind.

  • Page 30: Docking And Landing

    RUDDER TUNING You may adjust the rake of your rudder blades on your Hobie Getaway. The amount of rake in a rudder blade affects the "feel" at the tiller. Basically, more forward blade rake neutralizes the pull on the tiller and less forward rake increases the pull on the tiller.

  • Page 31: Trailering

    Towing a Hobie has particular hazards that should be mentioned. A Hobie is very wide. Obstacles should be given plenty of room when you are passing them. Tie down straps or lashings should be of sufficient size and diameter and placed on all four corners.

  • Page 32: Mooring

    Hobie Cat during competition. HOBIE CLASS ASSOCIATION The Hobie Class Association was started by a group of Hobie owners who got together back in 1968 to organize some racing and other activities. Hobie was the mainstay of the group promoting the activities himself.
  • Page 33 Basically, you put a taller mast on, use daggerboards, and go to a half round hull shape. The Hobie 18 is the end result of our efforts - mine, Phil Edwards' (my longtime friend and co-designer of the 18), and those of all the guys on our research and development team.

  • Page 34: Safety Tips

    • Sail to your experience. Do not try to do more than you can. Do not take the Hobie 18 out in the surf and do not head out for the ocean unless you are a real professional.
