The OSSA Powerlite system will probably be more expensive. How much more depends on how you are configuring the system. For example; Let’s say that you would normally use two 150 hp Yanmar engines and a 16kw Fischer-Panda generator. If you replaced this with a single 150kw OSSA Powerlite generator and a couple of 100hp OSSA Powerlite motors you would have a lighter system, better fuel economy and about the same “usable” power at virtually no additional cost. If you instead decided to use two 100kw OSSA Powerlite generators and a couple of 150kw motors, you would get even better fuel efficiency and greater redundancy, and considerably more propulsion power but the cost would be higher. In general, plan on the cost being around 150% to 200% what it would be with conventional equipment. For a typical new boat build, the premium paid for a complete OSSA Powerlite system adds about 5% to the cost of the boat.
