Maximum Passenger Weight

[DCockey]

keller34, perhaps you should call or send an email to Ski Supreme and ask them if they stated a weight capacity or maximum number of passengers for your boat, and if they did what it was based on.

With respect you're missing the point.

A boats speed is related to several factors. The first being at what displacement? The displacement is lightship + deadweight = trials or full load displacement. At THIS displacement and with the engines installed the vessel shall achieve a certain speed.

From this the deadweight can be broken down into fuel, water etc etc...and also passengers. Passengers = weight, which makes up part of the total deadweight which goes back to the trails condition.

Thus if one takes away all the consumables what is left..a weight of "something". That someone = number of passengers. A nominal weight of a perosn,a nd this is the only "legal" aspect about this is 75kg. No other laws/regulations are needed regarless where the vessel is or what type.

Otherwise for a boat manufacturer to state 11 seats and the weight of those passengers if on-board during a speed run does not make the claim speed...it is a blatant lie and misrepresentation. Upon which the boat manufacture may say...well...we accounted for 11 children not adults, or something like that.

If there are 11 seats, then it means only one thing 11 person may be seated. If the performance of the vessel, speed, and/or stability is not possible, then it can become "legal" as it is a false claim of both.

Either the boat can carry 11 persons or it cannot. It is that simple...

Ad Hoc, I understand your logic. I just believe it may not apply in this situation involving a recreational boat over 20' in length in the US. The world is not always as logical as we might wish.

I just believe it may not apply in this situation involving a recreational boat over 20' in length in the US. .

That is not logical.

If I take that very same boat and run the boat in say Italy, the boat doesn't change, the speed doesn't change and the max payload (dead weight) for a certain speed, does not change. Being in the US, or anywhere else, does not effect the performance/stability claims. Ergo..what is the deadweight of the vessel for the claimed/given speed?

I'd just get in touch with the govt dept that administers it for clarification.

I think the weight capacity is the main thing.

I wouldn't count on seating being for good performance or even adults.

I know with my boat I always kept it around 1/2 full of fuel. I could fill up for longer range, but handling suffered if I had more than 2 people with a full tank and I had to go faster to stay on plane. Good magazine performance tests give the amount of fuel and passengers during the test and best performance is usually not full.

There's a huge difference between six 35 lb kids and six 300 lb adult men on a small boat.

Also owners judgement is important. For example with a bowrider the bow seats are great for slow speed and nice days. Don't plan to use those seats on bad weather days or when jumping swells or wakes.
