* Boat/Passenger Capacity

Boat capacity is a critical issue. Traditionally capacity ratings were based on the assumption of the average person weighing 150 pounds. In 2011 the USCG changed to 185 pounds because  Americans have become significantly heavier. Injuries and fatalities from boating are a serious risk because of swamping (water enters a boat) and capsizing (when a boat is turn upside-down). Therefore, it is important to pay attention to being sure that your craft can safely handle a load, so serious considerations must be made for all the following:

· Passenger numbers and weight

· Cargo brought onto the craft

· Amount of onboard equipment

· Outboard motor weight

· Load distribution

An excellent source for determining capacity is found on most boats: the manufacturer’s rating plate. It provides critical information, including maximum load capacity. Often the information is broken down into maximum number of passengers and cargo. The owner’s manual also provides details on capacity.

We mentioned a formula that could be used for determining capacity:

1. Multiply the craft’s length by its width

2. Divide the result from step 1 by 18

3. The result of step 2 is the maximum passengers

However, as mentioned, the formula is based on an outdated average weight per person. It would be safer to use the formula to determine total weight capacity.

4. Multiply the maximum number of passengers by 185.

5. The result of step 4 is the total weight capacity.

Of course, the further you remain under any calculated or listed capacity, the safer.
