This is awesome!! Reminds me of the heavily armed Russian hydrofoils Sarancha/Uragan and Babochka!

Carbon-Vanilla already pointed out a few little issues, in all honesty I don't see any of the cannons being as much of a problem (30m cannons WERE mounted on the Russian hydrofoils after all) but the the placement of the missile launchers is trouble - they'll blow that conning tower right off!! Sarancha-class solves this by mounting them on the sides of the ship, and ships like Pegasus-class angles them outwards (since they're mounted on the rear deck)

The part about the screws too - they'll be out of the water! See how they're mounted on a Sarancha-class…

I'm sorry if any of this sounds picky! I know it's just concept design, and in that case people can take all the liberties they want, but I believe that the most effective concept design is a good combination of cool-factor and technical believability.

 I REALLY love the overall look of this vessel, it's sleek menacing! :D

Hydrofoils should be utilized more.

Now you only need to make them retractable so taht the ship can pass shallow water too. :P

Hydrofoil is always awesome for boats!

Love the integration of the hydrofoils

Very nice hydrofoil, I like! Used to love researching military hydroplanes when I was little. Very cool.

Sorry if my understanding of Russian is limited.

Pretty cool concept for a patrol boat but, that are a slue of problems in the weaponry and one particular design flaw.
First, having a twin 76mm auto-cannon is over kill for someone on the receiving end of the gun. The projectile of one shell has a diameter of about 5 inches. That's a big hole on the side of any boat and a sign of too much force.
Second, four 30mm twin-barreled machine guns is also too much force. The only existing gun that could compare would be a GAU-8/A Avenger; it is a 30mm hydraulically-driven seven-barrel Gatling-type cannon that is mounted on the United States Air Force's Fairchild Republic A-10 Thunderbolt II. It is among the largest, heaviest and most powerful aircraft cannons in the United States military. Designed specifically for the anti-tank role, the Avenger delivers very powerful rounds at a high rate of fire. Again, too much force.
Third, AA, stands for Anti-Aircraft; which is usually refers to a powerful long-mid range gun. That would probably be the only large caliber cannon you'd need on a boat like this but, for patrol purposes, I doubt it. A few salvos of SAM (Surface to Air Missiles) tubes would be more than sufficient in shooting down aircraft at a reasonable distance.
The hydrofoil design is a wonderful real world application, although not usually seen on military boats. However, it allows them to travel further at far greater speeds, the drawback is that agility is significantly limited to wide turns and shallow bodies or water are inaccessible. The problem in your design is that your props need to be even lower under the hydrofoils to provide the maximum amount of thrust the engines can provide.
Other than that, the idea could have real world applications.
