Thanks for the likes and replies, guys😊

Forgive my original estimate for the run time, Roy - I had only run it for perhaps 15-20 mins initially, so it was just an initial throwaway guess-timate, but you are correct; the battery is actually a 5-cell 2400mAh Nimh RX pack, and the speeds shown in the video were generally between 1 and 3 clicks of the throttle only, giving a good range of scalish speed. I have adjusted the run time comment to the maximum 1+hours, probably a more realistic estimate.
There is on bit on the video where I show full throttle and the boat does just about plane in a very un-tuglike manner, and this is after the ballast was added. If you read the build blog, I have mentioned a bit where I tried her out without ballast at the start, and found I had a speedboat!😆😉
I have yet to finish off the build blog as I have some photos of the lighting fittings etc to add, plus I hope to do an evening/twilight sail with the lights on and video it.

Best rgds to all,
Nick

I really like this entry in the Boat Harbour section; it's very detailed and informative.
Well done, Nick.

I have some problems with your figures! 2000mAh and 30 minutes run time say 3.5 amps would have the little tug planing! Would I be correct in presuming a 7.2 volt battery?

I run similar sized models all afternoon on a 2800mAh battery.

Looks neat and from a distance acceptable. I have a couple of GG's models and with just a tiny upgrade they look very good.

Perfect and a compliment! Looks good and floats perfectly.
