  • Twin Engines

  • Engine Brand: Perkins

  • Engine Model: Perama M 30


The engine area for the twin 29hp Perkins engines is midships. There is plenty of room to work comfortably due to the all sides access.

The advantage of having two engines is apparent during manoeuvres in confined spaces, the two propellers make it easy to keep the boat under control.

The starboard engine is fitted with a non-standard 75Amp alternator so that this engine can be used not only for propulsion but also as a generator to charge the bank of 6 batteries having a total capacity of some approx 900Ah. This arrangement works well in spite of the large electricity consumption (SSB radio, Radar, pressurised water system, electric windlass) the batteries are easily kept charged up.

The same starboard engine is also fitted with a calorifier to that it provides a continuous supply of hot water.

Just 30 minutes running time each day provides all necessary electricity and hot water, and consumes just half a gallon of fuel.

Another advantage of twin engine installation (the ultimate spare) becomes essential when one engine has an unexpected failure.

We have never experienced an engine problem due to dirty fuel – thanks to the gravity fed fuel system.  Its location within the engine bay ensures that whilst topping up via a dedicated pump, regular inspection of the whole engine areas is achieved.



  • MAX-PROP: 3 blade folding propellers

  • Twin rudders

  • Retractable Keel


The twin rudder configuration works well and the boat is easy to steer on all point of sailing. With the sails well trimmed the boat maintains her course easily.

A powerful B & G autopilot is backed up by the Hydrovane self-steering gear, which is mounted through the stern platform so that it forms an integral part of the boat. The Hydrovane self-steering system works independently of the rudders.

The lifting winged keel is undoubtedly one of the most envied and original features of La Aventura. A powerful hydraulic ram driven by an electric motor easily lifts the keel in less than one minute. For emergency purposes, there is a manual backup with a secondary hydraulic pump.

The lifting keel was totally removed from the boat during our maintenance haul out during Hurricane Season  2017 / 2018  spend in Guatemala – Western Caribbean.

The wing bolts were removed allowing the daggerboard to be lifted up through the dedicated inspection/ removal hatch.

The wing and daggerboard were fully sandblasted, prepared and painted before replacement.


Cutter rig. Hood Stowaway mast and jib furling system. Twin poles permanently mounted on the mast.

  • 1 x 110% – furling Genoa

  • 1 x Yankee cut genoa

  • 1 x inner staysail – hanked loose-footed sail

  • 1 x storm sail

  • 1 x In-mast furling mail -plus 1 spare

  • 1 x Starlight Lightweight Genoa (Cruising Chute)



12mm s/s 1x19 wire - cap shrouds and forestay and backstay – Norseman fittings

10mm s/s 1x19 wire - inner forestay, fixed runners, intermediates, forward and aft lowers – Norseman fittings


The sail plan ensures La Aventura has a good turn of speed under most conditions. The tall 54 foot mast can spread a lot of canvas and is essential to keep her sailing well in light winds, while the cutter rig offered us maximum flexibility under any conditions.

Roller furling gear is fitted to both mainsail and headsail. The in-mast furling mainsail and roller furling genoa lines lead back to the cockpit enabling boat handled by one person alone. The in-mast furling main has allowed us to reef easily and safely on all points of sail, in all conditions.  All our passages have been without additional crew and sailed by just us two.

Upwind sailing both with genoa only, and a staysail cutter add to boatspeed while maintaining balance.

The mast has a twin spreader rig, with an adjustable backstay.  Twin spinnaker poles are anchored at the base of the mast and stored vertically.

Our covered wheelhouse combined with the center cockpit has been one of the most envied feature from our fellow sailors.

The small wheel is offset to port, with standing room directly behind it and seating abaft. The view from the helm is good, the lower telltails and the horizon can be seen through the panoramic windows, whilst the mast top and mainsail are viewed through the roof hatches. The steering position has good vision of all the ‘corners’ whilst manoeuvring in a marina.

The B & G instruments sit in front of the wheel. Plotter screen is on the forward starboard bulkhead.  All winches and furlers can be controlled from the sheltered helm, as well as the lifting keel hydraulics, windlass and engine.  Sails shortening is actioned from the safety of the centre cockpit.

Self-steering- either by autopilot or Hydrovane meant that we hardly every steered by hand, and on the rare occasions when we did, it was during rough conditions when the sheltered steering position allowed us to safely and easily take over from our self-steering gear.

Our very enviable scoop-like transom serves as a wide stern platform for boarding from the dingy or from the water after swimming. A shopping trip is no longer a challenge.

Whilst living at anchor more than sufficient power is generated from the two solar panels and wind generator mounted on the stern arch.

On passages under sail constant power is generated from the Ampair towing generator allowing all night navigation and living onboard equipment to be kept in good shape.


  • ROCNA – 52lb/25 kg with 50m chain

  • DANFORTH – 45lb/20kg kedge anchor


Our Rocna anchor has never let us down – a great sleeping pill!


  • SEAGO - Four man canister life raft

  • GRAB BAG – SURVIVOR hand operated watermaker


  • 3 x Dry powder fire extinguishers; 1 x fire blanket, located in galley

  • 1 x Horseshoe with strobe; 1 x Horseshoe with Danbouy


The transom platform provides easy access to the liferaft which is mounted on the stern. The oceangoing raft can be launched without difficulty by any crew member.


  • LEWMAR:  5 two speed self-tailing: 3 x 30 and 2 x 52 in cockpit. 2 x 40 at mast

  • LOFRANS TIGRES: Electric Anchor windlass with cockpit remote


All furling lines lead aft making sail handling extremely easy, and sails are handled even in the strongest winds from the comfort and safety of the centre cockpit.

With a secondary windlass remote at the helm ensures those sometimes tricky med-mooring situations are easily achieved by just two persons.


  • CARIBE – hard bottom 10ft

  • YAMAHA -15 hp - 2 stroke


Our on-water taxi has great power and is a generous size– especially on a diving expedition. The dingy is stored on deck, fitting comfortable and safely between the foot of the mast and the cutter stay.


  • Two burner stove, grill and oven

  • ELECTROLUX: upright fridge

  • WAECO/COOLMATIC:  Top-loading refrigeration

  • Stainless steel double sink with pressure water

  • 12 volt fan

  • Fire blanket


The galley is narrow enough to offer security at sea, and passage cooking on either tack has never been an issue. The fridge/freezer arrangement has worked well for us as a couple. There is ample work surface and good ventilation. The amount of storage is the envy of many of my fellow sea- cooks.



Custom saloon with thick wrap-around lounge seating for up to 8 – uniquely positioned in aft

  • 2 leaf dining table with center bottle storage

  • 12 volt fan

  • SONY – Sound System CD AM/FM USB


The chart table is positioned forward facing in an area just at the base of the companionway steps. The table itself is big enough to work on and for bracing on either tack. The table is flanked by well laid our control panels, instrument repeaters, VHF, SSB, and radar display.

The main saloon occupies the entire aft section and is a wonderful open living area. Steel construction allows the area to be entirely open, from the port-side galley and starboard passageway to the navigation area.

The feeling of spaciousness is enhanced be the light ash interior, trimmed with beach. Two portholes in either side of the hull and two in the stern allows a view of the outside world, an unusual feature on a monohull of this size.   

The area is serviced well with a variety of storage areas and is well ventilated.


  • Number of single berths: 3 / 5

  • Number of double berths: 1

  • Number of heads: 1

  • 4 x 12 volt fans


Two sleeping cabins are placed forward of the companionway. The double berth starboard cabin takes up the entire width. This double cabin is very comfortable on either tack, and is an excellent sea berth.

Two single bunks, one over the other in the port cabin.

Navigators berth is on the starboard in clear view of the Nav station.

The aft Saloon area does not convert to sea berths. However in port/anchor these are 2 comfortable long and wide sleeping berths.

Storage in the aft saloon - Under the seating area there are 2 x port lockers and 2 x starboard lockers – each locker is approx. 2ft x 2ft x 1ft 6ins. Also there are 8 storage locker areas behind the backrest cushions in the aft area – all approx.  1ft 6in x 1ft x 1ft. All storage areas are lined with carpet

The watertight forward cabin has no berths – instead it provides generous storage space in a dedicated storage/workshop cabin with a work bench. It is a well laid out and practical area with deck access via an extra-large deck hatch. There are 2 dedicated storage compartments. Port has with a lid/work bench – approx.  4ft 6ins x 1ft 6in x 2ft. Starboard is an open locker – approx. 4ft 6in x 1ft6in x 2ft. Also on starboard side are 2 shelves 4ft 6ins x 1ft 6in x 1ft, secured with canvas lee sheets. This shelf area is mainly used for storage of ropes and sheets.

The deck remains uncluttered as everything is stored below deck in the dedicated forward cabin.
