"@Grant,
Consider an ROV wanting to head due north to a target, in a 2 knot easterly current. If it maintains a compass heading of north, the vehicle would end up east of the target. If the vehicle has a speed of 2 knots, the heading would be 315…"

"Tom,
It is great to use excess pieces, but be careful to have any open end sealed in the epoxy. If you don't the water will leak in under pressure. Using a heat shrink tubing which has adhesive applied on the inside makes a better seal, but still…"

"Nochin,
Take a look at Models by Design. http://www.modelsbydesign.co.uk/model_boats.aspx
They have a fiberglass catamaran that is a model of the wind farm service vessels called Wildcat 53. It come in 2 sizes, 50 inch length by 20 inch beam, and…"

"Tom,
If anyone has a T100 just use Archimedes principle, with either salt or fresh water.

"Hi Phil,
I have a similar kayak made by Pelican to be used for a USV. Some issues arose on initial testing, mainly the lack of a keel. Our unit is for very shallow water investigations, so a keel is not an answer. We tried tank steering with 2…"

"Hello Thomas,
The speed of sound effect is not as noticeable in a swimming pool. I used to teach my hydrography students the art of hydrography (it was a winter course) but we couldn't do any practical work due to the hard water in the lakes. (ice)…"

"Hello David,
What telemetry wires are you referring to; the signal from camera to transmitter?
Two things may happen. The foil may change the cable capacitance and cause skin effect changes, especially if the end at the camera isn't grounded.…"

"Hi Thomas,
Don't forget to measure the speed of sound in the water as well as the elevation of the water when you do your survey for silting. This is very important! If the Garmin unit allows you to enter a speed of sound, you can do it by doing a…"

"Hi Thomas,
There are thicker PVC tubes (usually called Sched 80) which we have used as a WTC up to 100 metres water depth. Deeper usually requires Aluminum tubing, but there are many other new materials that can be used. For depths greater than 100…"
