Bow thruster option would be great. Throttles are too close together for iPhone usage. Would be nice if they were spread out or moveable to control with two thumbs. Throttles accelerate the vessel too quickly.

I was hoping to get a little more insight on how to dock a twin engine motor yacht but two things made the experience very frustrating: first the motor yacht does not react/respond as a real one would. Applying throttle to the port engine only turns the boat, spins it actually. There should be some forward movement when applying throttle on only a single engine. The second thing that was frustrating are the screen controls for the engine throttle. It is far too easy to accidentally apply an input on one engine while trying to control the other. The controls should be further apart, perhaps even on opposite sides of the screen even though this is not how the controls are laid out on a real vessel.

The simulator concept is perfect the training is very good. The only problem i have with this app is that i drive a 2 engine boat and mainly you use your 2 throttle sticks to turn into a slip and park your boat but in this app the 2 handles are right next to each other and i can barely fit my both fingers to turn the boat. Thats my only issue i think it will be better if the right throttle stays in the right and the wheel in the middle and the left throttle on the left side of the wheel that would make it easier to turn using throttle controls and make the throttles wider to fit different finger sizes. Other than that this is so worth the buy.

The concept of this app would be wonderful. Unfortunately, at least for the sailboat, the way the boat moves is far from realistic. A sailboat has a center of pivot approximately midship, this app does not simulate that in the least. Also, the prop walk is very inaccurate. Overall, a huge disappointment, it is a pity, something like this app would be very useful if somebody gets it right.
