Sam designs in groups in his ongoing quest for unbelievable flexibility in boat design. The Blue Fin 54 is an adaption of the Blue Fin 48, which you should check out for the thought process behind her design. In the 54 variant, you keep the stunning efficiency and add more space and comfort, while keeping the fuel economy and designed-in ability to smooth out choppy waters. Sam has designed a single and twin screw version. The twin screw version offers a bit more performance and the ability to use the twin configuration for maneuverability in tight situations. The single screw version offers amazing efficiency for going the distance with minimal fuel burn. Our friend Temur Rukhaya has not only completed a sterling build of this design, he has given us real world data on the outcome of fuel efficiency. Read about Temur’s build here.

It would be hard to find a more sterling example of a customer built Devlin boat. This Blue Fin 54 was built by Temur Rukhaya and his crew in Russia. Temur named her the ‘Lucky Star’. He not only builds a beautiful boat, but he makes great videos as well.
Here is his showcase video for the ‘Lucky Star’.
In Temur’s own words…
About four years ago (or more) I ordered the Blue Fin 54 boat project.
In the spring of 2014 the boat was launched.
I called the boat “Lucky Star”
Today the boat ran over 8,000 nautical miles.
This year, I came to the White Sea and was in Sankt- Petersburg.
During this pass, I crossed about 100 locks. On Ladoga Lake was a heavy storm.
Technology “stitch and glue” deserves the best endorsement.
The boat is very comfortable, quiet, easy to use and on the go.
Temur was kind enough to make a build video.
Being a boat building company, we always want to know the details. Once again, Temur delivers in fine fashion.
Installed engine Vetus 231 hp / 2500 rev / min
Transmission 1: 2.78
Propeller 4 x 28 “x 27”
Displacement about 8500 kg
Fuel consumption: 14 knt – 0.75 l / km
9 knt – 0.5 l / km
Max. speed (unloaded boats) 16-17 knt
Two fuel tanks 1,100 liters each.
Diesel generator Vetus 4kW
Solar cells 6 x 140 watt
Water tank 2×230 liters
Black water tank 230 liters
Air Conditioning 9000 BT
Heating – diesel boiler combined with the engine cooling system.
When sailing – the boat is heated by the engine. On mooring – from the boiler(diesel heater).
Although Temur has noted the comfort, quiet operation, and ease of use of the “Lucky Star’, the hallmark of the Blue Fin 54 is her easy running efficiency. Here are his calculations for fuel economy.

Fuel Consumption (g/h)
As an example of what this kind of efficiency means in practice, look at this video of the acceleration of a 54 foot boat.
Our congratulations to Temur for a spectacular build, and our thanks for all data to go with it! All that information folds back into Sam’s ongoing understanding of how to design great boats across the spectrum of nautical goals and dreams. The ‘Lucky Star’ is more than a boat. It’s a builder’s example of what can be done with a dream, a design, and dedication.
Now, finally, some interior shots of the build, including the ever popular “Dog is my Co-pilot” shot. Lucky dog!
