Fuel Efficiency Means More Time Aboard
Experienced boaters understand that fuel costs can affect how much they can use their boats. While it is not the only factor, fuel-price fluctuations can have a serious impact on the amount of cruising boaters can do, the range of their cruising, and the time they can commit to the sport. That is why Aspen efficiency makes sense. Contributing factors to fuel burn on any boats, whether they are monohulls, multihulls, go-fasts, or slow cruisers, are weight, wetted surface, and appendage drag. To go faster other boatbuilders add more horsepower which means increased engine weight, fuel weight, equipment weight and appendages. Others find efficiency by simply going slow which means longer running times that ultimately add to fuel consumption. We prefer to approach the challenge another way, with a hydrodynamic hull form that slips easily through the water requiring less power to propel the boat. Aspens offer speed, efficiency, and performance without adding extra horsepower.
Our engine configurations provide power options to suit our owners’ needs, whether it is the smooth reliable power of an inboard diesel or the flexibility of two outboards of different horsepower matched to each unique Aspen hull.
On the inboard package, the reduced appendage drag of the single rudder and prop matches the asymmetrical hulls of the patented proa design.
The outboard package is designed to use both engines together but can use one or the other at a time, depending on the desired speed. For instance, the smaller engine acts as an efficient trolling motor when fishing.
