Albatross’ SEA VAN 1100

Albatross' SEA VAN 1100

Numerous speedboat accidents happen in Thailand; recently two Australian girls suffered severe spinal injuries causing the industry to re-think safe transportation. Tourist operators and insurance companies are keen on providing safe transportation to their clients, but still there is a problem with awareness among tourists and some authorities. Thailand-based design office Albatross Marine Design has an extensive record of developing catamarans in the range of 6-24m in length, now in service in many locations as passenger craft, dive boats or for pleasure use. By developing new catamarans, the designers tried to meet requirements for stylish, functional and safe craft in order to bring high-speed transportation to a new level, based on previous experiences with this type of craft.

The benefits of the catamaran for described application are:

Lower vertical acceleration levels, comprising 30-50% less compared to similar monohull craft. These numbers are based on full-size measurements on a number of boats. Lower accelerations on cats mean that the task can be solved on craft of smaller size, or they are able to maintain higher speed for the given seastate.

For craft with same passenger capacity, catamarans offer about 40% more saloon area per passenger, which results in more comfortable accommodation. This is possible due to better utilization of space on catamarans, which possess wide and spacious cabin volumes.

Albatross' SEA VAN 1100

The arrangement of the ASV1100 is quite simple – the passenger saloon with forward-looking seats are grouped into six rows of three seats each on both sides of the central passageway. The designers followed ergonomics and dimensioning of the economy class saloon of aircraft, but left a bit more space (900mm) between the rows. The steering station is located in the front part of the saloon at the starboard with console and seats for the crew of two. A small toilet is a must for 2+ hours voyages and is located at the bow port. The aft section is open deck used for passenger boarding through side doors. Side windows can be sliding, which allows excellent airflow and protection from the rain. In the front windows, there is an angle-shaped weatherproof door that is used for bow access for the crew and can also be used in case of forward boarding through the bow cockpit. The bow of the catamaran can be fitted with either a folding bow ladder (for beach boarding) or a bow ramp for dock boarding. Once lifted, the ramp becomes an integral part of the bridge-deck. Air-conditioning can be provided in saloon and is essential feature in tropics.

The ASV1100 possesses a typical planning catamaran hull shape with sharp chines, chine flats, a slightly wrapped bottom, and the hulls are of symmetrical type that have proved to be efficient solution in pre-planning and early planning.

The design of the ASV1100 is for stern-drive units based on Volvo D6 engines. Other engine options and drives including shaft drives and stern drives are available with simple modifications and inserts in the mould.

The hull structure is designed in FRP with PVC sandwich panels for the bottom, sides, deck, wet deck and superstructure. In general, the boat's structure is designed following ISO12215- 5 Small Craft standards, which proved to work well for commercial craft below 15m in length and is officially accepted for such craft in number of countries. The bottom is studied in Divinycell H130 foam and the rest of structure in H80, with multiaxial fabrics and polyester/vynilester resins. Stainless steel plates protect areas vulnerable to tear damage. Bow section below waterline is filled with foam forming 'collision block' – solution that proved to work well during unlikely accidents.

This craft is completely designed around passenger safety – comfort in terms of wave shocks on the seaway, protection in case of emergency stops, and there is no passenger access in areas vulnerable to damage - important in case of collision accident. You ca also use the ASV1100 option as an ambulance – important for the islands where there is no immediate access to paramedical services. The designers believe that hospitals would be interested in such a craft.

Main particulars: length of hull - 11.05m; beam – 3.9m, fully loaded displacement – 12000kg; engines – 2x370HP Volvo D6 (or 2x330HP with commercial rating); fuel – 2x750L; water – 200L, maximum speed – 32kts fully loaded; passenger capacity – 36.
Currently, the ASV1100 is being developed for the Southeast Asian market.
