Who Runs This Site

Mary Stone, Captain, M/V Ms. Astor runs this site…

Mary Stone has 34 years experience as an international consultant to fortune 100 companies using her background in the field of applied Industrial and Organizational Psychology.

In the late 1960’s and throughout the 1970’s she completed employment test validation projects for a major electric utility, and did extensive differential analysis of high performing organization indicators – correlated to factors measured in employee engagement surveys – for major oil companies.

In the 1980’s  she developed performance profiles that distinguished high performers from others using competency modeling, and established her own private consulting firm employing 14 consultants.

In the 1990’s she developed organization capability assessments and wrote books on the Malcomb Baldridge Quality Assessment Processes and on international virtual team processes. She conducted global organizational design projects for international joint ventures in the oil and gas industry and organization capability assessments globally in the Pharma industry.

She subsequently retired from consulting and is sailing the Caribbean as a single hand cruiser for the last 20 years.

She has maintained a strong personal interest in the analysis of yacht crime data in the Caribbean for 20 years.


Mary Stone spent a month in the spring of 2017 asking the CSI author for a substantiative  and professional discussion of the validity (or lack thereof) of the CSI. The only response was that CSI is a black box and if you don’t like it “don’t use it”. Mary Stone recommends to any cruiser that they should  not use the invalid CSI.

Her best suggestion is that each captain should remain up to date about  what has happened previously in a location and factor that into their risk analysis with all other information available to the captain. Her professional opinion is that there is no data available that will support a valid and reliable prediction of the probability that a captain, crew or vessel will experience a crime against a yacht in any specific location in the Caribbean.

At this time, only a captain, personally and individually, can assess the risk of crime against the yacht using all available information except CSI, which has not been shown to be valid.

Mary Stone has subsequently filed formal complaints of false, deceptive and misleading advertising of CSI to government, private and cross-border agencies that police false advertising. She has also notified the appropriate sponsors and advertisers in freecriuisingguides.com and Marina ZarPar that they are supporting an invalid and potentially dangerous product – CSI
