Sachi,
Imo for that length hulls the beam should have been around 7m and not for double the passengers, but specifically so it won't capsize. If it was two meters wide for instance it would capsize much easier. You can calculate the capsize moment wrt the beam width. I just use my female instinct with these things.

Unfortunately, in your part of the world, having standards and accepted practices in place for protections against unsafe designs or operation, is shall we say is "lacking".
As I mentioned very early in this thread, we just haven't a clue what this is all about. Now we have a hint and things are about as I suggested.

Now, I'm dieing to see a picture of the boat, just to confirm what we all must be envisioning about now.

After a quick search of capsizes in Malaysia, I found none (no news story, which in itself is interesting) that suggested an 80 passenger vessel capsized, but did come across several dating back to 2003, all of which were over loaded, most in "rough" conditions.

This leaves one to conclude that Sachi, needs to be more specific (date of incident, name of boat, location of incident, etc.) so we can get a real picture of what's going on.

If you're serious about your quest, then look at the stability book for the vessel. That will tell you who designed it, which class/flag state surveyed/approved her, what standards it is to meet etc etc.

USA's 46 Code of Federal Regulations, Subchapter S, Part 171.

(if aplicable in your country. Most probably you should have specific criteria for that kind of small domestic passengers vessel, issued by your national authorities)

Hire a naval architect and ask him/her to perform an stability test to the boat (if not lost) and recalculate to find if your country's mandatory stability criteria are met, including maximum allowed turning heel. If boat has been lost, then the NA can revise the whole stability booklet of the boat to search for possible faulty calculations if there are any.

This may also be of interest to you:
