The Spirited 380 is a good balance of fresh modern styling, excellent sailing performance and a generous amount of internal volume for a good functional layout. With good bridgedeck clearance of 700mm, will minimize pounding underway. Built using lightweight materials will help to reduce bridgedeck slamming and improve motion at sea, the boat will lift easily over waves without that sluggish momentum often experienced on heavy cats.

Flat side and forward decks, give clean lines and a more practical surface to walk on surrounding the tramps. Incorporated into the forebeam is a composite prodder, this is fixed or hinged and is designed to carry the inner forestay, main forestay and screecher which can all be kept in place on furlers, creating a ‘gearbox’ type effect when performance sailing, from the bigger sails down to the smaller.

The storm jib, which can be carried on a furler is fitted to the inner forestay. This is anchored to the catwalk with extra support from the composite prodder below, giving a good slot between the inner and main forestay for easily tacking the Genoa around. Having the storm jib on a furler means it can be used at any time as an upwind heavy airs blade jib when reefed down or for extra sail area when cruising downwind, if needed.

At the same height on the mast as the inner forestay are the lower shrouds running down to the edge of the cabin top, keeping the mid panel of the mast well supported and also the walkway on the sidedeck clear.

A carbon mast is recommended and combined with this well-stayed design; this is a ‘bulletproof’ rig. The rig size is in the ‘performance’ bracket rather than  being conservative, which means it will come in handy in light airs but will have plenty of power when the wind picks up. Reefing early is always a good option to take if the crew is inexperienced or short-handed. A flat area at the base of the mast on deck gives good footing for reefing and sail handling. This area also creates a vertical surface to mount opening hatches or windows leading into the saloon and forward bunks, great for vision and ventilation.

Cockpit
Cockpit


Walkthrough transoms Port and Starboard lead into the cockpit. Behind the cockpit is a swimming platform/duckboard area that runs the entire width of the boat. As you come up the aft hull steps you step onto the last step that is on cockpit floor level, and can either lead into the cockpit or onto the swimming platform.
Stylish composite dinghy davits are mounted to the main aft bulkhead and mainsheet travellor base, these are hinged and swing out of the way when the swimming platform is in use. In the cockpit there is plenty of seating, with a wide radial seat aft with a central table. There is corner seating either side forward directly behind the saloon bulkhead, which double as steering stations. A bench area against the saloon BH can be used for an outdoor basin or BBQ area with a slide out rubbish bin underneath. 
The extended saloon cabin top provides an excellent shade top for the cockpit with good headroom clearance below, and creates attractive clean lines.

Saloon

A large single door off-center portside provides access into the saloon. Big windows in the bulkhead create good flow-through between the saloon and cockpit areas. An ‘L’ shaped galley against the aft bulkhead on the starboard side makes sure the cook is included in the conversation both in the saloon or in the cockpit via a drop-down window in the aft bulkhead adjacent to the galley. Hot meals can be simply passed out through the window onto to the bench in the cockpit. The sweeping saloon seating has two areas, a dining area opposite the galley, and also a lounge area with a low ‘coffee’ table further outboard on the port side. On the end of the galley module is an entertainment unit set up for the TV facing the lounge area. On the starboard end of the saloon/dining seating is a bench area housing the fridge/freezer. This is directly opposite the galley, making this area very easy to get to. This also keeps this weight central for the trim of the boat. 

Starboard Hull

Access into the starboard hull is forward of the galley return, creating a large private aft double cabin with a generous open floor area. Forward of the hull steps of the midship section of the hull is an office or navigation area. Further forward in the hull is the forward double cabin, the double bunk is on the bridgedeck with steps leading up to it. At the inboard end of the bunk are optional opening deck hatches set on the horizontal surface surrounding the mast. This creates a very airy open atmosphere, usually this can be a very claustrophobic area in other cats. An optional opening hatch in the dashboard above the bunk gives extra airflow on those balmy tropical nights or to keep an eye on the young ones from the saloon. Forward of the front double cabin is the option of a walk-in-robe or an ensuite in this area of the hull. Usually this hull would have the ensuite and would be considered the ‘owners cabin’. 

Port Hull

Access into the port hull is alongside the saloon bulkhead, entering into the midship section of the hull. In the aft area in the aft cabin is the head, aft of the head is a separate shower cubical. Moving forward into the midship area, there is bench space inboard and lockers on the outboard side. This area could be utilized also as a bigger office/navigation station. The forward cabin is a mirror image of the starboard hull with a selection of either a walk-in-robe or ensuite as in the starboard hull.   

 

           

On - Deck Storage

Storage areas on deck are in the nose-cone section forward of the cabin, these are easy to access, with one each side of centerline. Also on the foredeck is a large sail locker in each hull. The sail lockers are ideal for storing spare fuel, spare anchor, fenders and other bulky items. In the cockpit there is plenty of storage space under the seats.

 Tramps

The style of trampoline shown on the left is the continuous rope system as used on the Spirited One. This is our recommended system; it not only looks great, is comfortable to use, cost effective and has an open weave allowing green water to pass though it easily. 

Motor Options

The recommended motors are 15 to 25hp sail drive diesel engines installed just aft of the main aft BH below the aft hull steps. The sail drive design works well for a few reasons: Firstly it is simple to install, especially for DIY builders, it is compact in size and runs smoother than a shaft-drive installation. The streamlined sail drive leg combined with a folding propellor, creates minimal drag. The legs are well protected by the fixed spade rudders in case of collision or grounding.  Some of the advantages of having the engines in their own compartment below the aft steps is keeping the leg clear of the bottom of the hull, it also isolates the engines from the accomodation area which benifits in reduced noise and vibration. Ask us about our range of moulded epoxy engine beds to suit some of the main brands of engines. These simply glue to the hull because of the use of a bonding flange.If shaft-driven diesels are preferred the only change is to the head and shower area, unfortunately the separate shower cubical must go. 
   

Daggerboards

The daggerboards can be built using E-glass or Carbon-fibre for weight saving with a chord length of 750mm. This board will be very efficient upwind and means that they don’t have to be as deep in the water, reducing the over-all draft of the boat. Being built using 80kg/m structural foam, they are light and forgiving if a collision were to take place, damaging the board rather than the hull is always the preferred outcome. All Spirited boards have a sacrificial bottom end to avoid not only damage to the hull but also to the board.

Payload

The payload includes anything non-essential to the operation of the boat. A boat without it’s payload would be in lightship trim and retain only enough fuel & water for basic operation. If the payload weight is kept to a minimum the difference will allow for a lighter boat.
