Is LPG the acceptable alternative?

摘要

The news that up to four new workboats des-tined for service on the River Hamble will be powered by Liquefied Petroleum Gas (LPG) once again focuses attention on this affordable and environmentally responsible alternative to petrol and diesel. When the first of two 6.2m catamaran harbour patrol vessels- enters service in late August (two follow-on craft will be configured differently, for taxi operations), its twin four-stroke 30hp Honda outboards will have very similar fuel burn to their petrol equivalents - about 6.5 litres per hour. But what other fuel costs only 25 pence per litre to buy!
