Two pontoon boat design approach and how to find center of gravity, center of buoyancy, buoyancy, volume of displacement, meta center, meta centric height.

I need to know is there a different approach to designing dual hulled boat than a single hulled boat and all the formulas and examples I can get please.

Thank you in advance!

Mostly, there is no difference, single hull - multi hull. What has your research told you so far?

You could look for examples such as the Suntracker fishing barge design.

One key feature of the design is compartmentalized pontoons so that a puncture of any given pontoon won't cause the boat to sink. However, if you hit an iceberg all bets are off.

Anorlunda is correct. There is no difference in determining the characteristics of the stability profile. Do be very careful that you do not fall into the common mistake of calculating one hull and not consider the other hull. The supplemental effect is amplified by the separation of the two.
The only real difference is that the wave interaction between the hulls at speed creates an unusual resistance interaction which can lead to performance challenges. What research you have done and the formulas you have found will help with finding where you are at.
