Practice, practice

Some additional brief outing video

The weather in Wilmington, North Carolina has become quite a bit colder as the last few days of 2017 turn to 2018. With the sun very low in the late afternoon winter haze sky,  Hillary pilots the boat on the Cape Fear River. 

While she drives, I assess the amount of power generated on the roof to replenish the battery banks used by the electric motors. We will be performing this same task many times during a wide variety of weather conditions at different times of the year. The worst time of year is winter.

of the difference between a Grand Banks 42 and the MOG 40.

The cold actually helps the collection on a sunny day due to cooler photovoltaic (PV) modules  and more clear air without humidity. Problems arise from a shorter winter day time and the sun being low on the horizon, thus not directly shining on the PV modules. The result is very poor collection of available energy. The reasons for the tests are to gather experience in handling reduced collection while dealing with water flows , wind and traffic.

We will endeavor to keep you up to date as our schedules and weather permit. Hope you had a wonderful Christmas and do have a prosperous New Year.

to Solar Boat Cpt. Jim Greer

Serene progress sliding across clam waters in the final version of RA, the solar powered boat.

We have been following the progress of RA and the solar electric boat's challenge to the Great Loop from its very inception as noted in this early adoption of a Roost USA, Inc. folding top.

Persistence is the hallmark of a champion and Jim has it in spades. His raw determination has served well to change, quite literally, the course of modern boating power. I and many others alike, doff my hat to the man whose dream to sail the Suwannee River went quite afar to complete the Great Loop on solar energy alone. Over 7,200 miles are claimed by the dauntless sailor of RA, a totally electric sun powered boat.

The face of determination, persistence and a nice set of whiskers, Jim Greer.

From comments made throughout his sojourn he often alludes to the fact that the boat is basic transport, not built for luxury accommodation. However, if you want to be the first to complete the Great Loop with the sun as your gas station in the sky, his boat, RA, definitely got the job done.
