The searchlight is made of monel as is the prop shaft and the railings. All navigational lights are operating and can be set for any type of tow as per the rules of international navigation. The searchlight is focusable as well. Runs on three 12 volt gell cell batteries , not the hobby type either. This model will run for about four hours.
Problem is that the transmitter battery goes dead long before that.
We tried this model out and she will tow a 17' Boston Whaler with 4 people aboard for as long as need be. Also required is 50lbs of lead to get her down to her load waterline. She'd make a great ice breaker as well. Stuffing box is stainless steel with teflon lining and requires no lubrication at all and doesn't leak a drop. Another of dad's engineering and building feats.
