In Sweden you can only buy sulphur free class diesel - its price is approximately 30% higher than yours in the UK.
The sulphur free diesel has approximately 8% less energy content than ordinary diesel - equivalent to approximately one prop size. This means with sulphur free diesel you get around 8% less for your money (except for the new Volvo Penta engines ) The stepped hull design we are doing for Sealine and Nimbus boats has about 8 - 10 % less drag than a normal comparison boat, which reduces the fuel cost by about 15 - 18 % compared at the same speed. The technology is a direct spin off from racing boats we have designed over 10 years with 14 World Championships in offshore racing.
The Sealine T50 is an example of new hull technology without a stepped hull but still very efficient. We are constantly researching for new hull technology to get lower drag and less waves.
