30ft Fast Patrol RIB - The Landing School, Maine, USA

This 30ft fast patrol boat design was completed as a final project for my recent diploma in yacht design at The Landing School, in Maine, USA. She is designed to meet all ISO class B standards, but satisfies many class A requirements and has 360 degree roll-stability as defined by ISO 12217-1. The vessel has the following particulars:

LOA: 32 feet
Beam: 10 feet
Draft: 21 inches
Light Displacement: 9,500 lbs
Maximum Speed: 47 knots

The vessel is a general-purpose patrol vessel (Law Enforcement/SAR/Port Security/Diving Ops) built in FRP, with structural design meeting ISO 12215. With a modified deep-vee hullform, hybrid air/foam collar and a heavy-duty recovery platform, this boat was designed as an excellent all-around vessel for use in harbours as well as near-shore patrol situations. Equipped with twin Volvo D6 370s powering Ultrajet 305s through ZF220 transmissions, this patrol vessel is capable of lightship top-speeds of 47 knots. Please see the systems spec below for more detailed information about this vessel and feel free to browse through some of the drawings that I’ve posted pertaining to this design.

As with all of my current projects, this vessel was designed using the following software:
Fastship for hullform modelling and hydrostatics
Orca3d for hullform modelling, hydrostatics & planing analysis (verified by ‘Savitsky’ hand-calcs & Ultrajet proprietary software)
Solidworks for all general 3D modeling
Rhinoceros for some complex surfaces
Hullscant for hull construction scantlings meeting ISO 12215-5
Autocad for all 2D drawings
Hypershot for all renderings
Excel for weight and balance studies
