INTRODUCTION
This research project will explore the magnitude and frequency of persons unintentionally falling and subsequently drowning in marina waters, and specifically whether this danger has been properly addressed.
In recent years, I have consulted with numerous marinas, both domestic and abroad. The majority of these marinas were located within the United States. Outside of the continental U.S., I have consulted with marinas in regions that include Canada, U.S. Virgin Islands, Bahamas, Panama, Cyprus, and Puerto Rico.
I am the author of the Marina Policy Guidelines manual, published in December 2016, by the University of Wisconsin, and was a co-editor of the first edition of the Marina Operations Manual, published by the International Marina Institute in 1989. I have taught at various International Marina Institute marina management courses, have been a presenter at the University of Wisconsin’s Docks and Marinas course, and the Association of Marina Industries International Marina and Boatyard Conference. In 2016, I created and continue to present the Marina 101 course for the International Marina Institute.
Through past experience, I have noticed what I believe to be an under-addressed danger within the marina industry: persons unintentionally falling into the waters of a marina and the inability to rescue those persons in a timely manner. Initially, this research began with a survey of what guidelines, regulations, and standards already exist for marinas addressing life rings, safety ladders, and fire extinguishers.
My findings indicated that most of the guidelines, regulations, and standards that exist on the use and placement of life rings and safety ladders are limited and ambiguous.
I then shifted my research to see to what extent persons may be unintentionally falling into the waters of a marina. The findings showed that there is an issue of persons not only unintentionally falling into the waters of a marina, but drowning in marinas as well.
This report discusses the findings on unintentional incidents of persons falling into and drowning in the waters of a marina, as well as existing guidelines, regulations, and standards on life-saving equipment to safely rescue those who have fallen into the waters of a marina.
RESEARCH FINDINGS
This research centers on persons unintentionally falling into the waters of a marina and subsequently drowning. The report does not include people intentionally swimming or jumping into the waters of a marina deliberately. During the time that research was being conducted, numerous news reports or marina and boating sources were identified that included information on drownings that took place in or near waterfront facilities or activities. While most of these reports and sources had information on drownings, the majority of the information had specific language indicating that the drownings were related to boating accidents or swimming, neither of which fit the parameters of this project. These reports or sources included, but were not limited to:
The vast majority of the research conducted was through online databases. Information collected for this project was for the period of 2008 through 2017. Most of the drowning articles found were published online by local newspapers and local news media. A spreadsheet categorizing the findings is included in “Appendix A.” (Appendices available as PDF in ‘Details’ section of this page)
This research has identified 107 drowning cases that fell within the established parameters of the project. Some information, such as the cause of the incident, was either not available or released at the time that an article on that drowning event was published. For information that was not available, those categories are simply identified as “unidentified.”
Refer to Appendix “A” for the detailed information collected on the 107 drowning cases that form the central focus of this paper.
HIGHLIGHTS OF THE DROWNING DATA COLLECTED:
Of the 107 marina drownings that were identified:
The gender breakdown of the drowning victims were as follows:
Age groups of the victims are:
Drownings occurred in all twelve months of the year. The number of victims drowning in each month:
Number of victims drowning on a seasonal basis:
Number of victims drowning during the week versus the weekend:
Number of victims drowning during the time of day:
7 of the 8 children had drowned on a weekend.
Various descriptions of how the person fell into the water:
12 of the drowning victims were persons that lived aboard their boats in the marina.
In summary, persons do fall unintentionally into the waters of a marina for a number of reasons; at different times of the day, week, and year; at any age; and in various states across the country, both coastal and inland. The majority (85%) of the drowning victims were male. Of the victims in which their age was identified, 65% of the victims were aged 45 years or older.
The time of the day was unidentified 37% of the time for drowning victims who entered the water. Causes of drowning incidents were unidentified 40% of the time. Both of these statistics imply that these drowning victims were alone when they entered the water.
PREVENTION
A number of precautionary measures, had they been implemented, may have prevented some of these drownings.
Children should always wear a personal floatation device (PFD) whenever they are near any body of water. Furthermore, when children are in areas where they may be prone to accidentally falling into the water, a responsible individual should always be with them.
When a person is walking the docks, embarking or disembarking from a boat, a “buddy” system should be used. According to the research data, 40% of the drowning victims fell into the water while alone and for unidentified reasons. If the drowning victim would have had a companion, some of these drownings may have been prevented.
Embarking and disembarking from a boat can be a dangerous event, each and every time. If a “buddy” or companion is unavailable, the person on board the boat should consider wearing some type of floatation device, in the unlikely event they would fall into the water. 12 of the victims were identified as persons living aboard their boat, while 11 victims drowned while embarking / disembarking from a boat.
Videos were recovered with respect to 5 of the drowning incidents. Video cameras are valuable instruments to monitor and record incidents. From the available information gathered, it appears that these video recordings did not have anyone monitoring the video feeds in real time. Unless monitored, the videos would be rendered largely useless as a preventative measure in detecting persons falling into the water although the videos still may provide valuable information as to what happened and how it can be avoided in the future.
Life rings should always be readily available at any waterfront facility. A life ring presents the opportunity for someone standing on the dock or pier to assist the person in the water. The potential rescuer may be a non-swimmer or the conditions in the water may be too hazardous for someone to climb into the water to help. Life rings need to be strategically placed so that they are readily accessible. The life rings need to be in good working order, and have enough line to reach persons in the water. The line should also be made of a material which allows it to float on the water. Having this line would allow the thrower the ability to retrieve and throw the life ring again. The floating line allows the swimmer to grab the line in case the life ring is not accurately thrown.
If a person is alone and the fall into the water goes unnoticed, a life ring will not help her or him in getting out of the water. Safety ladders placed throughout the marina could give the person a chance to exit from the water. Exiting from the water in a timely basis could be critical as cold water or other conditions could impair the ability of a person to physically use the ladder.
A combination of life rings and safety ladders at a marina could mean the difference of a person safely getting out of the water or not.

SAFETY LADDERS
Planning and Design Guidelines for Small Craft Harbors, ASCE Manuals and Reports on Engineering Practices No. 50:
“Ladders are generally provided on fixed and floating docks to allow emergency access from the water. In addition, where the tide range and fixed piers may not provide convenient berthing access at all tidal stages, ladders are also provided adjacent to the berths (from the finger piers). According to the requirements of UFC 4-152-01 (NAVFAC 2005), ladders to provide access to fixed piers (or floating docks) from the water should be provided at a maximum spacing of 120 m (400 ft) on centers [sic] or within 60 m (200 ft) of any work area.
Ladders should be a minimum of 406 mm (16 in.) wide and reach the lowest water elevation anticipated. Retractable or flip ladders may be used as an alternative to fixed ladders to avoid marina fouling of the lower steps, but they can be difficult for a swimmer to reach and pull down in case of an emergency. There are numerous commercially available ladders made typically of marine-grade aluminum or stainless steel.”
Various forms of “lifting ladders” are convenient for floating docks, where they can be kept in the retracted position until needed. For recreational small craft harbors, ladders are generally spaced according to the management’s anticipated needs, clientele usage, and safety plan. They are often placed at the ends of T-heads of finger piers (so as to not affect berthing in the slips), in fairways, or adjacent to bulkheads so that anyone who may fall into the water can easily swim to a ladder without crossing under or through piers and vessels or across main navigable waterways.”

FIRE EXTINGUISHERS
Fire extinguishers have little obvious value as a life-saving preventative device for persons who have fallen into the water. However, applicable guidelines as to the location and placement of fire extinguishers may assist the marina industry in identifying where to place life rings and safety ladders. The National Fire Protection Association (NFPA) has specific codes on where fire extinguishers need to be located in a marina. The NFPA codes for marinas are recognized by the American Society of Civil Engineers, an organization responsible for the publishing of Planning and Design Guidelines for Small Craft Harbors. Where the NFPA codes describe the placement locations for fire extinguishers within a marina, those locations could be used in defining placement locations for life rings and safety ladders.
National Fire Protection Association (NFPA) 303- 6.1.1.1.1:
Planning and Design Guidelines for Small Craft Harbors, ASCE Manuals and Reports on Engineering Practices No. 50, Third Edition, Fire Extinguishers:
“Chemical fire extinguishers for small craft harbors and marine facilities shall be provided as per applicable National Fire Protection Agency (NFPA), state, and local codes and regulations. For small craft facilities, NFPA 303 (2006a) specifies portable fire extinguisher requirements (types and locations), which primarily includes provision of an extinguisher at the head of each dock access point (gangway or pier) and thereafter so that the maximum travel distance to the extinguisher from any point on the docks does not exceed 23 m (75 ft).”
RECOMMENDATIONS
It is my recommendation that a dialogue or discussion commence with a national panel of marina industry experts and companies, such as: marina owners, marina operators, insurance companies, dock manufacturers, aquatics safety expert, and a human factors expert. This panel could be charged with the task of whether or not the placement and use of life rings and safety ladders should be uniformly addressed in the marina industry.
Utilizing research data presented in this report, the following thoughts should be considered:
Create “Safety Centers” within the Marina
Each “Safety Center” is to include:
“Safety Center” location considerations:
Marina Safety Center Identification
Placards or signs next to each safety ladder:
Each “Safety Center” is to have the surfaced deck area in a bright contrasting color from the rest of the pier and surrounding area above and by water. This bright contrasting color will make the “Safety Center” easier to identify, both from the pier and from the water. The description of the bright contrasting color is similar to the description listed in the California Code of Regulations: #4405 - Working Over Water: “The dock area immediately adjacent to ladder locations shall be painted a contrasting bright color;” and
Include a raised pennant marker which is readily identifiable. This will allow a person to locate a “Safety Center” above the congested view of boat bow pulpits, power pedestals, and dock boxes.
