Disregarding the fancy electronics and technology speak, I still feel that physics would prevent this from being possible. Just a quick refresher on key concepts of dynamics and kinematics. F=ma in which F stands for force, m stands for mass and is a measure of an object's resistance to change in velocity, and a stands for acceleration. A constant acceleration would be your ship going from a stop to full speed, from full speed to a stop, or your ship changing the angle of its motion at a continuous rate. A constant acceleration causes a linear change in your velocity because of the relationship of v=at in which v is velocity, a is acceleration, and t is time. A constant acceleration causes an exponential change in displacement, because x=vt in which x is displacement. So lets assume the ships all take about the same amount of time to reach full velocity, and that the ship you would be trying to board is the Onslaught whose fastest attainable speed is about 100 units (which we will call m/s for simplicity's sake). The boarding pod's speed can be a generous 250 m/s and also reaches full velocity in 5 seconds. So the best possible acceleration for the Onslaught is 20 m/s
2 and the best possible acceleration for the boarding pod is 50 m/s
2. Let's also assume that the Onslaught's mass is say... 500x's greater than that of the boarding pod. Now that's pretty generous, but that also means the net force produced by the Onslaught's engines is conservatively 200x's greater than that of the boarding pod. I don't know how massive the Onslaught is, but even if the boarding pod's mass increases proportionally, the difference in forces between the pod and the Onslaught will also increase dramatically. So lets say that the boarding pod is half a ton. That means that the force exerted by the Onslaught's engines will be 5,000,000 Newtons. This also means that the forces exerted by the pod at full capacity will be 25,000 newtons. So worst case scenario, your computer makes a mistake and accelerates your pod into the onslaught as it is accelerating resulting in a grand total of 5,025,000 net force on the pod. That is a lot. Saying that the average human is about 150 kg's, then average gravitational force experienced by a human every day is approximately 1,500 newtons. Big difference. And don't even start talking about using grappling hooks, let alone magnets. Grappling hooks depend upon how strong the material they are made out is. Nothing really stands up to even a fifth or a tenth of the above force. And magnets? Really? Electro-magnetic forces would be so weak compared to 5 million newtons. So even assuming that the ships don't accelerate to the greatest of their abilities, you are still looking at huge forces being applied to smaller ship and ultimately, humans. Also, the ships can be going at about the same velocity which could lead to a frame of reference in which the ships are basically not moving at all, but even so, if a ship accelerates, then that change in velocity will still be expessed within that frame of reference. Sorry to if I got the physics wrong. There are probably a few guys on this forum who know this better than I do, but you know... You have to try. Also, sorry if I got sarcastic or rude anywhere in there. I do think this is a cool idea, but the realism and practicality of its implementation just doesn't make this a viable option right now. Also, I have noticed that the game already breaks a few physics concepts, especially when it makes your ships max out their speed. The only force acting on your ships is the thrusters so in reality, any ship should be able to go as fast as it wants, granted it has enough time. Ok well someone prove me wrong so a I can go be embarrassed.
