The boat Shangri La was originally designed as a 38 foot steel cruiser by Långedrag Marin in Gothenburg. In agreement with the designer Rolf Modig, the boat was extended by 1 meter and a bathing platform was added. The boat now measures 42 feet. It was originally constructed for 1 engine but since the displacement now became much larger, it changed to 2 engines, as this gave considerably better heeling properties, maneuverability and safety. An additional advantage of 2 individually controlled motors is that the bow thruster is superfluous.

Shangrl La has 5 mm plate thickness at the bottom, 4 mm in hull sides and deck, and 2 mm in the superstructure. The keel rail is 10 mm thick. It is equipped with dual stainless steel rudder blades which are operated by means of a hydraulic steering wheel pump and hydraulic cylinder from a 30 tons wooden ship. The boat is equipped with two freshwater-cooled Volvo D67 engines of 120 HP. They are equipped with hydraulic reversals and are converted by the Swedish Navy's fabric workshop. They were completely new when they were installed. Operating time up to now is approx. 50 hours.

Because the boat is not over 4 meters wide, the captain's degree is not required. The two engines give the boat a top speed of about 10-11 knots. The boat's most economical speed is 6-7 knots knots using one engine. The boat is equipped with 2 stainless steel acid-proof water tanks of 135 liters each, a fuel tank in ordinary steel of approximately 440 liters and a stainless steel acid-proof septic tank of 150 liters which is connected to an electrically flushed toilet. The boat is also equipped with a water distributed heating system which is currently heated by a wood-burning stove and a 2 kW electric heater, but it is planned to replace the wood-burning stove with a 5 kW diesel heater. To heat the shower water there is a gas-powered heater. There is also a washing machine that washes 3.5 kilos, which is powered by a 2.5 kW 230 volt generator. There is a 230 volt 1.5 kW innverter that is powered by solar-charged batteries for the operation of electric equipment with less power requirements. Shangri La was launched in the summer of 2014 and has since been inhabited by summer and winter by a person up to now. It has always been only in Vänern's fresh water and the total operating time is about 50 hours.
