I know there's a formula to calculate the maximum number of passengers on a

boat of a certain size. What's that number for a 34' x 11' Marine Trader?
What is a prudent number for a river cruise?

Hi Larry,

The following link :
http://www.boat-ed.com/ms/course/p2-1_knowyourcapacity.htm
had the following to say:

On boats with no capacity plate use the following rule of thumb to calculate
the number of persons (weighing 150 lbs. each, on average) the boat can
safely carry in good weather conditions:

          Number of people  =   (boat length (ft.)  x  boat width (ft.))

/ 15

That would make a MT34 theoretially capable of carrying 27.5 people.

Once I had 9 aboard "Angelina" and it was about as much as I could stand.

Titanic warning:
You must have a wearable PFD for each POB and one extra type IV throwable PFD.

Have fun,
Al Johnson

Larry, Al, et al;

Despite what any formula tells you, the real answer is whatever number
is on the manufacturers plate. No matter what a formula tells you, if
the plate says 8, the formula says 10 and you have 10, the Coast Guard
is still going gig you for being overloaded. Al's other comments are
dead-on, too, about the PFDs.

A further concern - watch your lines. Had an occasion where 40 or so people
got on a large Hatteras for a fire works show. Floated fine but Captain
shut off engines. Boat was far enough down on lines that one engine flooded
and was destroyed on start up. Simply keeping engines running fixes
problem. ( Our little yacht club in Catalina did this periodically - it is
much simpler to move a mess of people on one big boat than handle the
logistics for five or six - particularly for well attended events)

That would make a MT34 theoretially capable of carrying 27.5 people.

That would put 16 people on my Hullmaster 27. In actuality two get
into each other's way - unless, of course, she is very friendly...
