Author Topic:   130 ss reduced person capacity

mjwhaler posted 02-02-2009 11:36 AM ET (US)
I was comparing the 2008 and 2009 130s and noticed that the USCG rated capacity for the 2009 is 4 persons while the previous design is rated for 5. I reviewed the specs of the two models and there is minimal difference between the two. The 2009 has 1 inch less beam, 40lbs heavier and is rated for 10lbs more engine weight. The max total rated weight capacity and swamped capacity remains the same. The only difference I can see is seating configuration with the removable cooler seat on the 2009 vs the fixed bench on the 2008 ( I like the open configuration of the 2009 with the option to remove the center seat for more deck space better). Just curious if anyone has ony insight on why the person capacity would be reduced when the total weight capacity remains the same.

I think my 81 is rated for 7 people.
Because the boat is 40lbs heavier they probably lost a person or else it would be like every person could only weigh 105lbs.

I'm still searching but I believe there was a change to the rating system. The USCG used to use 140 pounds as a standard person's weight. I'm pretty sure they raised it to reflect our expanding waistlines. Thusly lowering the person capacity of new boats.

I know it is effecting the Ferry and other types of boats. I think they bumped it to 180 and some boats lost like 100 seats, etc. I wonder if they do that with airplanes with all the fat arses I usually have to sit next to. Heck I have a 36" waist and barely fit in those seats.

I know that the new standard for weight loading per person for a fire truck went from 200lbs to 250lbs.

I know there was talk of them changing the weight per person number but a search of the USCG website makes no mention of that. Perhaps it hasn't been updated yet.
I believe the weight per person is 141 pounds. In testing, when they come up with a capacity value in pounds they divide by 141. Then they round up or down. If it comes to 4.5 people they can say 5 person capacity. If it comes to 4.4 people the capacity is then 4 persons.
I got this information from the USGC Boat Builder's Handbook, title 33 part 183.41.
So the added 40 pounds could have put it in a lower per person capacity.
I think I interpretted it correctly.

NMMA, ABYC, and CG now use 150lbs. as the weight of a person. But they have also seriously upgraded the weight of "propulsion equipment", which is the real determining factor in capacity. In my opinion, it is not a valid measuring yardstick, as the difference between a 115 Etec and a 135 Honda are substantial, but you have to use one weight, according to Table S-30 of the latest NMMA manual, which, unfortunately, is at work.

I believe that the reduced capacity is due to the seating. The cooler seat that is along side the console is an option. On the old model you had more seating available. since the cooler isn't standard it can't be counted as seating.

I can't imagine 5..much less 7 people, in a 13' boat.
4 folks in my 170 is about 1 too many.

I'm not sure of the numbers, but it was mentioned in Workboat magazine that they increased the weight used for calculating the persons capacity of commercial vessels to reflect the greater size of the average American. It was either 140 and they raised it to 160, or 160 and they raised it to 180. I think the former.
I have no idea if this same standard was applied to recreational vessels. Just remember, these are guidelines not hard and fast rules. Use your brain to calculate the total weight, and use a little judgement when loading the boat to see how it sits in the water. A little common sense will prevent 90% of waterborne tragedies.

I have had 4 adults and 6 kids in my 13. I was ferrying my sister-in-law and her family (along with my family) to a beach on the lake and just when we got the picnic started a storm came up and we had to pile everyone in at the same time and make a run for the ramp. I am pretty sure I was over the weight limit and it was pretty tight! We had no problem getting on plane with the 48 Evinrude on the back. I definitely would not have tried that in any other boat.

According to the US EPA, a reference person for the purpose of conducting risk assessments is 70 kg, or 154 lbs.
