Compared with the classic deep-V hull theory based boats, all K-TOUGH Hull based boats will ride with fundamentally different behaviors that will change landscape of today's industrial capability for high speed boat operating safety, performance and comfort, detailing as follows:
Unlike the classic deep-V hull theory based boats that are rocking from portside to starboard and then again and again when riding at low/displacement speeds, the K-TOUGH Hull theory based boats can do low speed move extremely stable just like walking on land(video available as proof), securely extremely high level of comfort in low speed maneuvering for coming alongside quayside or leaving the harbor, which is of vital importance for pilot transit and the shifting of pilots between the pilot boat and commercial ship in adverse conditions;
Unlike the classic deep-V hull theory based boats that are highly lifting the forward hull section above water when transmitting the speeds from displacement speeds to planing speeds, the K-TOUGH Hull based boats are transmitting its riding mode from displacement speeds to planing speeds smoothly and gentle without significant bow up, because the unique hydrodynamic characteristics of the underwater section of our boats has been set to allow oncoming water to meet the dynamic forward waterline entry to evenly lift the whole boat along the hull length rather than simply hitting the forward hull section of the boat to cause a high water slope like what is found in the classic deep-V hull theory based boats;
Unlike the classic deep-V hull theory based boats that are riding with very exciting and unstable behaviors that get the dynamic forward waterline entry to be always changing and for most of the time to significantly move back to the midshio hull bottom and even the aft hull bottom to allow oncoming waves to directly hit the midship hull bottom to cause strong vertical acceleration to be imparted to both the hull structure and the crew onboard, the K-TOUGH Hull theory based boats can self lock their riding behaviors to sustain extremely smooth, soft and stable ride even over 60 knots and with nearly no speed loss even in open sea waves---The V-shaped bottom to meet waves in our boats at high speed has the deadrise angle to be approx. 60 deg. While the V-shaped bottom for competing boats to meet waves at high speeds only has the deadrise angle to be around 25-28 deg., which means our K-TOUGH Hull based boats can easily cut through waves to make the way ahead without effort, thus hull slamming has been fundamentally reduced to extremely low level, which is a very irreplaceable capability for a modern fast response pilot boat because real-world mission is always combined with tough weather;
Unlike the classic deep-V hull theory based boats that are maneuvering with extremely large heeling angle and high tendency of throw-away phenomenon and side skidding, the K-TOUGH Hull theory based boats can self stabilize themselves even when doing very high speed sharp turning, making safe tactics operation secured with confidence;

i. Vessel Layout:
The vessel is laid out with the hull to include one reinforced anti-collision fore peak tank, one void tank with watertight access hatch for stowage of manual operated anchor and its dedicated nylon rope, one fresh water tank compartment with one small cabin above the flooring of same watertight compartment, one fuel tank compartment and one void space for stowage of service items while the deckhouse is laid out with one large fully closed, air-conditioned deckhouse to accommodate two separate functional areas for the medical service and the boat control as per shown in the GA drawings.
ii. Hull Form
The hull is well proven and will be variable deadrise deep V high performance planing in form, incorporating a fine forward entry, two well immersed and full-length outer tunnels(also called revised reverse chine), extended waterline length, wide chine beam, high freeboard, flared bow above waterline, slightly curved down buttock lines from stern transom till 3/4 of waterline length, down angled and wide chine flats on bottom sides of the mid hull body, giving a softer ride and safer handling with superior stability in all sea conditions, providing high speed maintained in waves while also having capability to self correct when running in following seas.
ix. Strong Bow Protection:
The bow will be structurally reinforced to enhance abrasion resistance and then to be externally protected with over-sized, he
