Are you asking an academic problem or you really want to build one?

 

As an academic question, this is one a primary school student should be able to solve in under a minute. As for design requirements.....

What is the minimum freeboard? maximum freeboard?
What are the maximum surge, sway, heavy, roll, pitch, and yaw? their rates? their accelerations?
What is the operational sea spectra? survival spectra?
What is the operational wind speed? survival wind speed?
Deck load?
Paint system? Biofouling rate? Service life? Docking schedule?
Questions? Questions?

firstly it is an academic question
& the quesion was written as professor told us
thx again
bye

Homework

I don't know where "pal" is so I can't offer to do it for a couple* beer.

Just in case you are close I will get you started by mentioning that pontoons usually have air in them (cheap) or foam (the water repellent kind).

If this doesn't help I think you should hire Steve thats not a bad rate.

* Sailer terminology for enough beer on the table to see the project to completion. I break out in sweat just thinking about work - home or otherwise.
