CUSHION SYSTEM
This craft has the legendary Sevtec skirt and cushion system giving world-beating stability, safety and controllability. Craft can cope with wave chop up to one metre safely (more at reduced load) and will never plough in - unlike most other hovercraft! It can reliably transport up to four adults fort under almost any conditions (max. load is 461Kg). This craft is well proven with over 15 years of operation in UK coastal waters, it is a ‘proper’ hovercraft – not a toy.

TRAILER
plete with a fully galvanised custom drive on/off braked trailer. Loading and unloading only takes a few minutes and can be easily carried out single-handedly. Trailer has a spare wheel included. Decking is still perfectly functional but may need partial replacement in future (using low-cost 9mm ply). Gross weight (including 440Kg craft) is 760Kg so easily towable with almost any small car.

ENGINE
... is the renowned Subaru EA81, producing around 71HP @ 4000 rpm. To reduce maintenance and extend life, the engine is ‘marinised’ – including a full stainless steel exhaust system, all galvanised framework, stainless fixings with sheet metal parts removed or replaced with corrosion resistant alloy. Engine is fitted with the reliable Weber 32/26 carburettor.

SKIRT
The skirt is a low-pressure loop type manufactured from readily available PVC coated fabric (610 to 900gsm weight – commonly used by curtain-sider trucks). A replacement skirt costs around £350 for materials and around 10-14 hours work (hardboard templates are supplied and full instructions are included in the planset - process assistance is available from the UK HoverClub dot org dot uk website).
EQUIPMENT

Seating:
Supplied with two boat-grade seats on swivel, gas strut bases for fort in chop. There is also an upholstered rear bench seat for additional passengers.

Hood
A rain hood is supplied which attaches to the windscreen edge and lift duct. It is stored under the side deck and can be fitted or removed in a minute or two. During craft operation, it can be left attached to the rear bulkhead and folded back to sit above the rear bench ready for rapid deployment.

Instrumentation:
Dashboard display includes GPS speedometer, tachometer, coolant temperature, oil pressure and charge warning indicators. A DSC VHF marine radio is installed (GPS location data is supplied by the speedometer module).

Controls:
Standard boat-type throttle on RHS stringer – red lever is throttle (back to increase revs), black is choke (back to apply choke). Sevtec skirt vent ‘brake’ pedal is on floor under steering wheel (allows control of the nose, can be used as a brake on water and amplifies steering input). Steering is via dual 33c type industrial control cables to air rudders. Other controls include windscreen wiper (two speed with wash/wipe), navigation lights and bilge pump. Cabin heat is supplied via car-type controls on dashboard (multi speed fan with screen demist).

Fuel System:
Fuel tank (located under rear bench seat) is 30 litre capacity (around 4 hours duration with reserve – about 90miles range). Fuel filter (with water trap) and fuel pump are in the partment.

A box of spares is also supplied - located LHS under bench seat - and additional parts, including an engine block are also included. A fire extinguisher is located forward of the LHS dash bulkhead and an automatic lifejacket is also included.
