Welcome to the family of Tiara Yachts boat owners and congratulations on your purchase of
your new Tiara Yacht.
We understand there are many choices available to you, and we appreciate the investment
product. Hopefully, during the selection and buying process, you discovered that each Tiara
has been designed, engineered, and built with care and precision.
When our company was started, it was the goal of my father, Leon Slikkers, to provide you
part of that includes a delightful ownership experience. Everything we have achieved since our
humble beginnings has been with this same goal in mind.
The information within this owner’s manual was assembled to assist you in understanding
how to operate your boat to obtain the maximum enjoyment of your Tiara Yacht. So
please take time to read the manual completely and please operate your boat safely and
courteously.
I would also like to ask you a personal favor. Shortly, you will receive a survey asking
for your opinion about the sales process you experienced when you purchased your
ownership experience. By taking a few minutes to complete these surveys, you will be
providing us with valuable information.
Best wishes for many happy hours aboard your new Tiara Yacht,

TIARA YACHTS, INC. LIMITED WARRANTY COVERAGE
Tiara Yachts, Inc. (Tiara) provides limited warranty coverage on Tiara Yachts products sold for use
by retail (non-commercial) customers, as described in this Limited Warranty. For customers in the
U.S.: this warranty gives you specific legal rights; you also may have other rights, which vary from
state to state. For customers in the European Union: the purchaser may have additional legal rights
under applicable national legislation governing the sale of consumer goods, and those rights (if
applicable) are not affected by this warranty.
This warranty is provided only to the original purchaser of the boat from an authorized Tiara Yachts
dealer but can be transferred to subsequent owners. Contact Tiara’s Customer Relations Department
if you need information about transferring this warranty. No warranty coverage is provided to
subsequent owners unless they follow Tiara’s transfer procedures. This warranty does not extend or
apply to anyone else. The terms of this written warranty cannot be changed or modified, except by a
written agreement signed by an officer of Tiara Yachts, Inc.
COVERED PRODUCTS AND LIMITATIONS:
Tiara’s limited warranty coverage applies only to:
1. Defects in materials and workmanship in the boat and all components and accessories (except
for the excluded items described below) for a period of two (2) years;
2. Structural defects in materials and workmanship in the hull and deck for a period of five (5) years;
3. Blistering due to defects in material and workmanship in the gelcoat surface of the hull bottom for
a period of five (5) years, provided that the gelcoat surface has not been altered in any way such
as sanding, sandblasting or application of a coating other than standard antifouling paint, any of
which will void this warranty.
Each of the warranty coverage periods runs from the date of purchase of the boat from an authorized
Tiara Yachts dealer and applies only to warranted defects that first manifest themselves and are
reported to Tiara within the applicable warranty period. Tiara retains the right to determine to its
reasonable satisfaction whether any claimed defect is covered by this warranty.
Certain items are excluded from warranty coverage by Tiara, and this limited warranty coverage does
not apply to:
1. Engines, transmissions, generators, air conditioning systems, swim platforms and lifts,
seakeeping systems, electronics and batteries, and other components manufactured by other
manufacturers. These products may come with separate warranties from their manufacturers;
see the Owner Packet for warranty registration requirements and details on these products.
2. Dealer final assembly and pre-delivery commissioning, and dealer installed components.
3. Scratching, chipping, discoloration or flaking of any powder coated or painted surface including
engines and hardtop components.
4. Gelcoat stress cracking, chalking, fading or discoloration. This includes bilge gelcoat.

boat, or misuse or abuse, or deterioration resulting from normal use (including gaskets, seals,
springs, wipers and sealants).
6. Maintenance, adjustments or realignments to any components including latches, hinges,
hatches, doors and drive train components.
7. Mold, mildew, upholstery damage or deterioration and cleaning.

Tiara Yachts, or an authorized Tiara Yachts dealer with Tiara’s prior, written authorization.
10. Damage which has occurred as a result of the boat being operated as a demonstrator and/or
displayed for sale.
11. Damage or deterioration of the hull or deck structure due to the attachment of hardware or other
components.
12. Weight, speed, fuel consumption or other performance characteristics.
13. Damage or deterioration resulting from improper trailering, hauling, launching or storage.

REMEDIES UNDER THIS LIMITED WARRANTY
If a defect covered by this warranty occurs, Tiara (or one of its authorized dealers, as determined by
Tiara) will repair and replace the defective component, in its sole discretion. This ‘repair or replacement’
remedy is the exclusive remedy under this warranty. Tiara has no responsibility or liability for any
consequential or incidental damages, such as loss of use, storage charges, interest or finance charges,
insurance or depreciation, transportation or lodging charges, or charges for towing or hauling out, etc.
which are specifically excluded and disclaimed from this warranty. For customers in the U.S.: some
states do not allow the exclusion or limitation of incidental or consequential damages, so the above
limitation or exclusion may not apply to you. UNDER CERTAIN APPLICABLE LAWS, THERE MAY BE
NO IMPLIED WARRANTIES OR GUARANTEES FROM TIARA APPLICABLE TO YOUR BOAT, AND
ALL IMPLIED OR STATUTORY CONDITIONS AND WARRANTIES (INCLUDING ANY WARRANTY
OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE) AND GUARANTIES ARE
DISCLAIMED WHERE ALLOWED BY LAW. TO THE FULLEST EXTENT ALLOWED BY LAW, ANY
AND ALL APPLICABLE IMPLIED WARRANTIES AND GUARANTIES (IF ANY), INCLUDING ANY
IMPLIED WARRANTY OF MERCHANTABILITY OR PARTICULAR PURPOSE, ARE LIMITED IN
DURATION TO THE DURATION OF THE APPLICABLE PROVISIONS OF THIS WRITTEN
WARRANTY. For customers in the U.S.: some states do not allow limitations on how long an implied
warranty lasts, so the above limitation may not apply to you.
RESPONSIBILITY OF PURCHASER
1. No warranty coverage is provided by Tiara unless the customer and dealer complete and return
all Vessel Registration and Customer Acceptance Forms to Tiara Yachts, Inc. within seven (7)
days after delivery of the boat to the original purchaser.
2. The original purchaser or approved transferee must notify the Tiara Yachts dealer from which the
boat was purchased of any claimed defect within fifteen (15) days after first detecting the claimed
defect. Warranty work in excess of $500 requires Tiara’s prior written approval.
3. If the dealer fails to satisfactorily repair the claimed defect within fifteen (15) days, written notice must
then be promptly given directly to Tiara. Tiara is not responsible for unreported warranted defects.
4. The boat, including any claimed defective part, must be returned to the Tiara Yachts dealer from
which the boat was purchased (or to another dealer or facility as directed by Tiara Yachts) within
the warranty period for inspection and warranty service. The expense of returning and transporting
the boat or any part for warranty service, and the expense of returning and transporting it back to
the owner after repair or replacement, is the responsibility of the owner, and will not be reimbursed
by Tiara.
5. If the dealer from whom the boat was purchased is no longer an authorized Tiara Yachts dealer,
contact Tiara for instructions on how to obtain warranty service.
S2 reserves the right to improve its products through changes in design or materials without being
obligated to the owners of the boats of similar or the same model of prior manufacture. We may be
