The hull design work was undertaken by Adam Younger of K4+ Ltd., to meet the exacting demands and specification of Clyde RIBS.
Clyde RIBS wanted a hull which both be adaptable in its uses and would give a safe, comfortable and capable platform suitable for covering long distances with ease in "typical" British sea / weather conditions, delivering the crew with minimum fatigue.
K4+ have drawn on much experience and knowledge gleaned from previous RIB designs incorporating and blending many proven successful solutions in achieving the goal for the hull.
The hull has a double chine arrangement which gives the craft handling characteristics of relatively narrow beam craft at planing speed, with that of a wider beamed craft at displacement speeds. The main deadrise angle at the stern is 22 deg, with camber in this section for increased strength and efficiency. The "outer" deadrise angle is 35 deg, giving a compound angle of 25 deg. Both the deadrise angles increase in the forward sections of the hull form, ultimately merging to one surface with a deadrise of over 45 deg . The overall effect giving extra buoyancy and importantly improved interior dimensions without compromising other aspects of performance. The main deadrise surface is also complimented with three spray rails per side. These dramatically increase the efficiency of the hull whilst making a comfortable sea boat with soft riding characteristics and a very dry hull with more spray being deflected.
The tubes have been designed such that they run clear of the water at speed thus reducing drag. The extra stability offered by the tubes comes into play when turning at speed or in rough water. The tubes compliment a high shear line which gives excellent rough water handling and an extremely dry and secure ride. Tube diameters and taper can be varied to suit individual taste and / or operating requirements of the craft.
