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/145
owner should become proficient in all aspects of handling the vessel under sail and power, and be well versed
with emergency procedures before undertaking any offshore passage. The owner is further responsible for any
required state registration or federal documentation, accident reporting, outfitting the vessel with proper safety
equipment, and the safe operation of the vessel. J/Boats is happy to refer the owner to Boating Safety Courses
or other seminars available.
This guide is prepared to help owners understand proper rigging, tuning, and operation of the J/145. Please be
sure to complete the enclosed warranty card and mail to TPI Composites, Inc.
This guide is furnished for your benefit, but shall in no way be construed as any sort of warranty or contract,
express or implied, creating any obligation 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 TPI Composites, Inc.
