What is the load and passenger limits for the C-25? Let me know if this number includes engine weight.

Thanks

There is no load capacity certification on the 25. I have had 6 adults on board and 2 children. You obvously want PFD's for everyone.

Load capacity does not include the engine. I think the equation for boats without capacity certs is Length X Width divided by 5. Given that it would be 6.7. Google USCG Boat Capacity Formula and you will get another formula which has to do with weight of water displaced X the height of your antenna divided by the size of your anchor........

The Coast Guard only certifies boats less than 20 feet for HP and load capacity. However, Code of Federal Regulartions Title 33, 183.35 States that the maximum weight capacity of an outboard powered boat shall not exceed 1/5 of the maximum displacement and the weight of the boat. The maximum displacement is defined as the boat sunk to the level in calm water where no water comes aboard (usually over the motor well) and with only one hole up to 3" sealed. (ie the hole where steering and cables exit the hull to the motor well. There is no federal enforcement of weight capacity, but some states have cited boats for being over loaded.

It depends on the conditions and judgement of the skipper as to how to load his boat. Also remember that the previous federal standard of the "weight of a person" was 140 lbs, established in 1942. The current average weight was raised to 185 lbs after the sinking of the Edith Allan.

So I would say that 6 to 8 would be the max I would put aboard a CD 25.
Yes, you could use the boat as a 6 pack charter boat--but I think that in heavy seas, this would be marginal. I also base some of this on the fact that the CD 25 has a self bailing cockpit and an almost watertight cabin.

So would you say about 1400 lbs max in addition to the engines?

Thanks

I was recently entertaining friends on the boat while it was docked in my slip. We had 5 adults and 6 little kids (ages 1 to 7). I have the full camperback canvas, which extends the passenger area safety for little kids (none were allowed to wander around unchaperoned.)

We all fit! I would NOT want to leave the dock with that many people especially with that many little kids. Of course, mine were the worst of the bunch trying to turn on everything they could reach Crook

A quick guess at the combined weight of all the people that were onboard is 1100 lbs + stuff (wine, cheese, diapers, etc.). I would say 1400 lbs would be about right.

Let me emphasize that we never left the dock, but she didn't appear to be sitting any deeper in the water than usual....of course the cheese may have affected my vision a little. Laughing

I tried this formula,

and I came up with 3067 metric tons!

If this is true, then I can invite my mother-in-law on the boat Smile

p.s. - Of course, I'll have to be on the dock when she's in the boat.

p.s.s. - Lovey, just in case your reading this...of course I'm kidding! Rolling Eyes
