What makes something sink or float ? If it weighs less then the water is displaces it'll float.
So today was my 1st outing with a new toy (scooter) but I needs to get its weighting correct for neutral buoyancy and the leads placement for horizontal trim.
Played about before the dive with the weight, thought I'd corrected it to getting it as close to buoyant at 1ft per min.
Off we go and I discover it's now nose heavy so as soon as I release the trigger down the nose goes, made for a (slightly) less then enjoyable dive.
So I tried removing all the lead from inside the scooter and placement it externally where I can adjust its amount and location.
Now it's more buoyant then before and requiring more lead to sink.
Am I correct in thinking that when it was within the scooter it had more of a negative effect, as no more water was being displaced as before ?
