Introduction
WELCOME ABOARD and welcome to the J/Boats family of owners. Your boat is designed and engineered to be
the strongest, best performing, easiest-to-use, and most comfortable sailing boat of its type.
Sailing involves risk, most of which can be minimized with advance planning and proper seamanship. The J/88
owner should become proficientin all aspects of handling the vesselundersail and power, and be wellversed with
emergencyprocedures before undertaking any offshore passage. The owner is further responsiblefor any required
state registration or federal documentation, accident reporting, outfitting the vessel with proper safety equipment,
and the safe operation of the vessel. Your J/Boats Dealer will be happy to refer you to Boating Safety Courses or
other seminars available.
Please be sure to complete the enclosed warranty card and mail to C&C Fiberglass Components, Inc. (CCFC)
This owner manual is furnished for your benefit, but shall in no way be construed as any sort of warranty or contract,
express or implied, creating anyobligation on the part of J/Boats, Inc., with respect to any fact or facts or any advice
or opinions contained herein. The sole and exclusive warranty of the product is the CCFCWarranty described in the
appendix hereto and on the Warranty Card furnished with the yacht.
J/BOATS, INC. HEREBY DISCLAIMS ANY AND ALLWARRANTIES, EXPRESSOR IMPLIED, INCLUDING ANY
WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE OR ANY IMPLIED WARRANTY OF

J88 OWNER MANUAL 5
CE Certification:
CE Design Category:
With standard equipment the J/88 meets Category B or C Requirements for CE Certification.
CE Certification Notice:
This manual has been compiled to help you to operate your J/88 with safety and pleasure. It contains details
of the J/88, the equipment supplied or fitted its systems and information on its operation. Please read it carefully,
and familiarize yourself with the craft before using it.
Even when your boat is categorized for them, the sea and wind conditions corresponding to the design
categories A, B, and C range from strong gale to severe conditions, open to the hazards of a freak wave or
gust, and are therefore dangerous conditions, where only a competent, fit and trained crew using a well
maintained boat can satisfactorily operate.
Ensure that the anticipated wind and sea conditions will correspond to the design category of your boat, and
that you and your crew are able to handle the boat in these conditions.
This owner's manual is not a course on boating safety or seamanship. If this is your first boat, or you are
changing to a type of boat you are not familiar with, for your own comfort and safety, please ensure that you
obtain handling and operating experience before "assuming command" of the boat. Your dealer or national
sailing federation or yacht club will be pleased to advise you of local sea schools, or competent instructors.
This owner's manual is not a detailed maintenance or trouble shooting guide. In case of difficulty, refer to the
boat dealer, builder or its representative. Always use trained and competent people for maintenance, fixing
or modifications. Modifications that may affect the safety characteristics of the craft shall be assessed,
executed and documented by competent people. The boat builder cannot be held responsible for
modifications he has not approved.
NOTE: Any change in the disposition of the masses aboard may significantly affect the stability, trim and
performance of your boat. Users of this boat are advised that:
All crew should receive suitable training;
The boat should not carry more than the manufacturer's recommended load;
Bilge water should be kept to a minimum;
Stability is reduced by anyweight added high up;
In rough weather, hatches, lockers and doorways should be closed to minimize the risk of
flooding;
Stability maybe reduced when towing or lifting heavy weights using a davit or boom;
Breaking waves are a serious stabilityhazard.
In some countries a driving license or authorization are required, or specific regulations are in force.
Always maintain your boat properly and make allowance for the deterioration that will occur in time and as a
result of heavy use or misuse of the boat.
Any boat – no matter how strong it may be, can be severely damaged if not used properly. This is not
compatible with safe boating. Always adjust the speed and direction of the craft to sea conditions.
If your boat is fitted with a life raft, read carefully its operating manual. The crew should be familiar with the
use of all safety equipment (harness, flares, life raft, etc.) and emergency maneuvering (man overboard
recovery, towing, etc.); sailing schools and clubs regularly organize drill sessions.

J88 OWNER MANUAL 6
PLEASE KEEP THIS MANUAL IN A SECURE PLACE, AND HAND IT OVERTO THE NEW OWNERWHEN YOU
SELL THE CRAFT.
Definitions of CE design categories:
A OCEAN: Designed for extended voyages where conditions may exceed wind force 8 (Beaufort scale) and significant wave
heights of 4 m and above but excluding abnormal conditions, and vessels largelyself-sufficient.
B OFFSHORE: Designed for offshore voyages where conditions up to, and including wind force 8 and significant wave heights
up to, and including, 4 m may be experienced.
C INSHORE: Designed for voyages in coastal waters, large bays, estuaries, lakes and rivers where conditions up to, and
including, wind force 6 and significant wave heights up to, and including, 2 m may be experienced.
D SHELTERED WATERS: Designed for voyages on sheltered coastal waters, small bays, small lakes, rivers and canals when
conditions up to, and including, wind force 4 and significant wave heights up to, and including, 0,3 m may be experienced, with
occasional waves of 0,5 m maximum height, for example from passing vessels.
NOTE: The significant wave height is the mean height of the highest one third of the waves, which approximately corresponds
to the wave height estimated by an experienced observer. Some waves will be double this height.

J88 OWNER MANUAL 7
J/88 Recommended Loading
ISO 12217-2
Category B - Maximum Crew = 6 People at 75 kg (165 lbs.) each.
Category C or D - Maximum Crew = 8 People at 75kb (165 lbs.) each.
Category B or C Manufacturer's Recommended Maximum Total Load = 911 kg (2,008 lbs.) - includes crew
This assessment has been made assuming that all standard equipment is aboard and that the boat in light craft condition has a
mass of 2,302 kg. (5,078 lbs.) This recommended maximum load takes into account the mass of the following:
a) The number of persons onboard: Where children are carried as part of the crew the maximum number of persons may be
exceeded provided that each child's mass does not surpass a limit of 37.5 kg (83 lbs.) and the total persons mass (75 kg) is not
exceeded.
b) basic equipment mass of (LH-2.5)^2 considered not to be less than 10kg.
c) stores and cargo (if any), dry provisions, consumable liquids [not covered by d) or e)], and miscellaneous equipment not
included in the light craft mass or in b);
d) consumable liquids (fresh water, fuel) in portable tanks filled to the maximum capacity;
e) Consumable liquids (fresh water, fuel) in permanentlyinstalled tanks filled to the maximum capacity;
f)a life raft or dinghy when intended to be carried.
This boat has been assessed using the Stability Index(STIX), which is a measure of the overall stability safety and considers
the effects of boat length, displacement, hull proportions, stabilitycharacteristics and resistance to downflooding. This
assessment has yielded the following data:
J/88 Minimum Operating Condition:
STIX = 31.36
Angle of Vanishing Stability = 131 degrees
J/88 Loaded Displacement Condition:
STIX = 28.82
Angle of Vanishing Stability = 123 deg.
J/88 is equipped with 610mm height double wire lifeline system supported by SS stanchions as well as SS bow
and stern rails for man overboard prevention. A stern boarding ladder is standard for man overboard recovery.

J88 OWNER MANUAL 10
Getting Started With Your J/88
Generally, your dealer or commissioning yardwillhelp you prepare yourboatbefore launching. And in most
instances they will undertake the entire commissioning job. They are experts in the field and are capable of
completing most commissioning tasks.
BeforeProceeding
Before you begin to assemble your new boat you should become familiar with the different sail control
systems and associated hardware. All running rigging and loosedeck hardware items are shipped from the
factory in parts boxes. To help you properly install these items please refer to the rigging and hardware
sections and diagrams inthis guide.
The Commissioning Checklist: will help you double check that the J/88 is assembled properly and all
systems and rigging are functioning properly. If a boatyard other than an authorized J/Boat dealer is
performing the work, review this list with them to establish what needs to be done and by whom.
Topsides: wash off all dirt and grime accumulated from delivery. Use only non-abrasive cleansers on the
gelcoat. Then apply a coat of high quality car or boat wax to prolong the life and sheen of the gelcoat.
Bottom: Bottom preparation is critical to long-lasting enjoyment. To ensure a professional finish, carefully
review the paint manufacturer’s recommendations for preparing the bottom. Be sure that there is a healthy
amount of epoxyprimer (using paint manufacturer build-up recommendations) to cover the keel and rudder
PRIOR to final coating of bottom paint. Avoid use of copper or anymetallic based bottom paints on or in the
proximity the aluminum Saildrive leg. Saildrive leg should also be thoroughlycoated with epoxyprimer and
any nicks or scratches properly sealed.
Chainplates: are manufactured of polished stainless steel. Shroud chainplates are mounted directlyto a
highly reinforced area of the hull flange and attached to large aluminum backup plates. The backstay
stainless steel padeyes are bolted to a reinforced area of the transom.
Stemhead Fitting: is a custom stainless fabrication bonded to the hull inside the foredeck anchor locker
area. The stem head fitting is engineered to withstand all headstay loads.
Mast StepTabernacle: is a custom stainless fitting for a deck stepmast arrangement and incorporates two
large stainless pins that attach to a matching mast step plate bolted to the deck. This deck plate includes
an internal chase way to allow mast wires to enter the boat. There are locations for halyard and reefing line
turning blocks on each side. The carbon mast sits atop a G-10 mast base plug and a SS thru-bolt prevents
the mast from jumping off the plug. With the forward pin removed, the tabernacle arrangement allows the
mast to hinge aft during unstepping.
Toe Rail: J/88 is equipped with molded toerails at the deck edge forward of the mast and support toerails
in the cockpit for the helmsman and mainsheet trimmer just aft of the cockpit seats.
Stanchions & Pulpits: are designed for proper offshore safety as well as to facilitate access to the boat.
Optional are two full length lifeline gates to port and starboard. The double lifeline arrangement includes (2)
standard sternlifelines. All stanchions andrails are1”diameter stainless steelwith smaller diameter inboard
support legs on the stanchions. Optional black powder coat is available for stanchions and rails.
