documentation, maintenance records, income/expense 
histories, and often an on-site inspection.
• Intended use: Appraisals for financing emphasize lend-
ing risk; insurance may focus on replacement; litigation 
requires extra defensibility.
ASA-accredited appraisers in MTS bring specialized train-
ing, peer-reviewed reports, continuing education, and ad-
herence to ethical standards. The ASA designation signals 
rigorous qualification: education, exams (including US-
PAP), years of experience, and demonstrated competency.
WHY THESE STANDARDS MATTER 
FOR THE PVA COMMUNITY
In an industry where vessels represent major capital in-
vestments, USPAP/ASA-compliant appraisals protect 
operators, lenders, insurers, and buyers. They reduce dis-
putes, facilitate smoother transactions, support insurance 
placements, and aid in strategic decisions like fleet renewal 
amid green transitions. Banks’ preference for ASA-certified 
work underscores the need for professionalism. “Experience 
alone” valuations without documented methodology fail 
modern scrutiny and expose parties to risk.
As the passenger vessel sector innovates—with autono-
mous tech, sustainable designs, and new routes—valuation 
methods must evolve while maintaining core USPAP 
principles of competence, objectivity, and transparency. 
Engaging qualified ASA appraisers ensures values reflect 
both current market realities and long-term utility.
Operators should view professional appraisals as invest-
ments in clarity and risk management. Whether financing 
a newbuild ferry, insuring a historic excursion boat, or 
preparing for sale, adherence to these standards provides 
the foundation for informed decisions in a competitive and 
regulated industry.
