SolarWinds is a 42 x 21 feet / 12.8 x 6.4 metres James Wharram design (Captain Cook) catamaran.

The tender - a 1/4 scale of SolarWinds. It will have its own solar panel, batteries in the hull, and driven by an efficient electric motor.
The boat fitted with wingsails in 2000. The wingsails have since been removed, and in their place in the future, there will be an inflatable wing (approx. 7 x 1 metres) filled with a gas lighter than air. The wing will hover 1 metre above the beam and will be released when needed.
The boat with the wingsails viewed from a different angle (2000). In the future, a key feature of the boat will be to have the next generation of solar panels, but I will not use batteries to store solar energy. There are alternatives to power the boat through the use of solar.
Construction in the garden (1982-1993): 25 cm from the wall, in a trench 1/2 metre deep and 25 cm from the garage.
The right hull is leaning to give space to work on the other hull.

HEATING: The same concept applies for a house, where although there is energy on demand, it can still be made energy efficient. As with a house, heating can be a major energy requirement. It must be analysed to its basic form and major sources of heat loss must be taken into account. Many of those who live aboard tend to use either diesel, coal, wood, gas heaters or generators. All of these require large amounts of air to produce combustion. During the winter, the amount of cold, highly humid air brought into the boat is matched by the warm and dry air expelled. With respect to a boat, this is unacceptable if energy requirements are limited.
