Head check on Max Capacity and Max Power Calc.
Posted: Sun Jul 24, 2016 11:34 pm
I apologize in advance for the tedious question on calculations, but I wanted a double check on my calcs.
I am adding a 3rd toon (with build int transom) to a 28ft pontoon as part of a restoration. All three tubes are 21 inch "U-style" with Styrofoam inserts. I assessed using the Canadian construction standard, but it wasn't clear if a tritoon is calculated the same way as a traditional pontoon. Here is what I came up with (keep in mind I had to covert everything to metric, then back to standard).
Max Capacity
GW = ((72m^3*1000kg)-1000kg)/2 = 3100kg = 6,834 lbs (~ 41 people)
Max Power
MP = 3(8.5m X8.5m)*0.5m = 108kW (~145 HP)
I ball parked the the total weight of the vessel at 1,000k (2,200 lbs), but honestly I am not sure what the final weight would be. I guess Iam concerned that 41 people seems like too much and 145 hp seems like too little.
Any help would be appreciated.....even if it is to go back and take high school algebra.
Thanks,
Rooster
