Hodewu, welcome to the forum.

There is another forum in internet, dedicated to pontoon boats only. So you could try to post the question there as well: http://www.pontoon.net/fusetalk/forum/index.cfm?forumid=3

Cheers

You get only 8.5 kts with 450 HP and 12-13 tonnes total weight? There is something wrong with either those numbers or your boat...
Can you give some pics of your boat, pontoon hull in particular?

 

And how did you manage to put 100 pax on a 12x4.5 meters boat?

 

Good question Daqu, but I think the answer may surprise you!

May have prior experience in sardine cannery.

Without a lines drawing or good pix, I doubt any help will be forthcoming.

 

Need pictures ,need pictures ,need pictures :?::

 

With a full load, what is the immersion (depth) of the pontoons, relative to their diameter? What is the diameter of the pontoons? Length of the pontoons?
