We do not believe in "accidents" as this infers that there was no avoiding the incident. Since human factors are involved, crash causation is perhaps a more accurate term. This can be as simple as a speed too great for existing conditions (sea-state, fog, water depth, other vessels/narrow channel, improper look-out or radar watch. Each and every crash has a human element that must be examined in the greater scope of the entire crash.
To accurately determine the cause of a crash, weather reports, tide conditions and chart analysis must be performed. The course (or direction) of vessels must be determined as well as establishing what "Nav" rules applied and how these were followed.
Causation is simply the final product that we provide for our clients.

Crash investigation can involve the minutes or hours leading up to the crash itself. Depending on each individual fact pattern, actions (and omissions) prior to a crash are key elements in the overall investigation. The investigation will involve weather elements, human elements as well as "Nav" rules and mechanical elements.
No investigation is complete without a clear report and court presentation. We can provide a complete analysis of a crash or the policies & procedures of a marina or boat rental establishment that MAY have contributed to a crash.


Accident or CRASH reconstuction is the process of taking each piece of physical evidence and fitting them together. This may involve time and distance calculations, lamp examination, damage assessmentor even fitting to boats back together so to show each vessel's path thru pre-engagement, engagement and post engagement sequences.
By using the investigative techniques mentioned, the United Stes Coast Guard navigation rules (1972 Colregs) can be applied to the incident.
Many vessels are equipped with a global positioning system (GPS). These systems if retrieved early in an investagation can be downloaded to reveal speed and course of the vessel.
It is also extremely important to know the differance between a marine surveyor, a salvage company and a Reconstructionist. Many times a surveyor is mistakenly contracted to analyze a crash. Only a Reconstructionist is properly trained to investigate a crash and present these findings in a court of law. Here we excel. As founder and lead investigator with over 25 years experience of courtroom experience, the staff includs licensed Captains, harbor patrol officers and suport staff. This experience includes district and superior court as well as federal district court as well as expertise in multi-media presentations.

Boating accidents (crashes) or boating incidents come in many different forms. Certainly boat v. boat (including Personal Watercraft- PWC) are the most obvious. Other times excessive wakes are a factor. Overloading, inexperienced operators, failure to follow the "Nav" rules other factors in boating crashes. A marina or rental facility failing to follow procedures or policies may also contribute to an incident. All of these factors must be explored in a boating incident.
Captain Expert and staff is equipped to investigate all types of watercraft crashes.

Although fully trained in land based crash reconstruction, we limit ourselves to watercraft investigations only.
The experience of conducting numerous land based crash investigations has however, allowed us a strong foundation in processing scenes and determining cause.

There are times when physical evidence is "lost" to the seabed or lakebed. Although rare, this evidence can be detailed and mapped by side scan sonar if need be. Another option is to photograph the evidence by way of diver or remote control camera device. When needed, he is ready to address these needs and recover this important evidence.
His goal is to finish its clients with the most complete report he can provide.
