Extra pics to help build .
note stern has a rounded edge, missed on most builds.

Found this on the net, I hope it may be of use, I will use to try to build a new scratch build, unfortunately there is not a stern or bow view!

Watercat M12 seems to have disappeared there is a article on the model boats magazine web site

http://www.modelboats.co.uk/news/article/watercat-m12--u619/14635

The model is kitted to a scale of 1:16 which gives a model hull length of 35 inches and 10 inches beam. The kit includes a GRP hull,

In the late 1990s, the Finnish Navy began to modernise the mobility and equipment of coastal defence forces. Marine Alutech Oy Ab designed and developed the WATERCAT M12, a new type of a troop carrier for the Finnish Marines for landing and transportation purposes in all weather conditions.

The water jet system gives the boat excellent manoeuvrability and can stop almost within one boat’s length from full ahead. An essential advantage in coastal use is that the bottom of the boat is perfectly smooth, enabling the boat to operate in very shallow waters safely.

There are 20 damped seats with seat belts on the fore deck and the deck is sheltered with a light composite cover. Hatches on the cover and a hydraulically operated bow ramp ensure fast unloading and loading of cargo and personnel.

The equipment includes the latest marine electronics and communications systems. Low noise level (under 75 dBA) and ergonomically placed instruments help the skipper to handle and operate the boat safely and comfortably despite rugged military use. For military and patrol purposes the boat can be equipped with two 12.7 mm machine guns.
