Hobie SPORT CRUISER 21 User Manual

WELCOME TO THE

HOBIE WAY OF LIFE

Congratulations on the purchase of your new HOBIE 21 Sport Cruiser and welcome to the HOBIE® sailing family. The beauty

of the 21 Sport Cruiser is that a single adult can sail it at top performance - and a crew of four can cruise in comfort.

We offer this manual as a guide to increased safety and enjoyment of your new boat. The purpose of this publication is to

provide easy, simple and accurate instructions on how to get your Hobie 21 SC ready for the water. Please read them

carefully and familiarize yourself with the boat and all of the parts spread before you.

Whether you are a new sailor or a veteran of many years, we recommend that you read this thoroughly before your first sail

and TRY IT OUR WAY FIRST! If you are new to sailing, this manual alone is not intended to teach you how to sail. There are

many excellent books, videos and courses on the safe handling of small sailboats. We suggest that you contact your local

sailboat dealer, college or Coast Guard Auxiliary for recommendations.

Watch for overhead wires whenever you are rigging, launching, sailing or trailering with the mast up. CONTACT OF THE

MAST WITH POWER LINES COULD BE FATAL! Be certain that the rigging area and the area that you will be sailing in are

free of overhead power lines. Report any such power lines to your local power authority and sail elsewhere.

We take pride in presenting the Hobie 21 SC to you and hope that you'll take as much pride in owning her.

Fair winds and good sailing!

8. WINGS

8.1 Identify the left and right wing assemblies.
Red Dot = LEFT
Green Dot = RIGHT

8.2 Mark the legs with tape as shown. These

points indicate full and complete insertion of
the legs into the hull. (FIGURE 8)

8.3 Put the right wing legs into the sockets and
place the right seat onto the legs. All parts are
pre-drilled so the holes should line up properly.
Rivet the seat onto the legs using rivets and
rivet caps. (FIGURE 9)

8.4 Lace the wing tramp as shown. (FIGURE 10)

8.6 Before sailing, secure the wing legs on the
hull with a short piece of line. (FIGURE 12)

NOTE: INSTALL WING TRAMPS SO
LACE LINES DO NOT INTERFERE WITH
CUP HOLDERS (FIGURE 11)

WARNING:

WINGS WILL NOT FLOAT!

CAUTION

It is very important that the wings are

completely inserted when sailing or

whenever any load is applied to them.

Failure to completely insert the wings will

result in hull and/or wing damage. You

have inserted the wings completely when

the band of tape on the outboard side of

each insertion tube aligns with the top of

the hull deck.

8.5 To insert the wings, simply work the leg

tubes into the hull sockets an inch or so at a
time. Push one leg of the wing into the tube,
then the other and continue alternating until
both sides are completely inserted. If the wings
cannot be easily inserted using this system,
check the end caps and sockets for debris
(such as sand), improper fitting or metal burrs.
