Thread updated with part three: the boat.

 

Don't you think that skeletons could be despawned due to long transportation? Or even won't be spawned if the player is too far away from mob spawner?

 

Despawned? No, I had no idea...but I did think about it: what we want to do is make a mob 'grinder' and while standing there, waiting for skeletons, we can choose to stop them and kill them or to let them flow through. I now even got an idea for a counter, counting the amount if skeletons...can they despawn? Really? If so, from what distance on...? Anyone?

 

According to wiki "a monster spawner is only active when a player is within a radius of 16 blocks from the spawner."
And about despawning:

• A mob that has had no player within 32 blocks of it for more than 30 seconds has a 1 in 800 chance of despawning on each game tick (1/20th of a second). Therefore, the half-life of monsters not within 32 blocks of a player is 27.73 seconds (after the initial 30 seconds have elapsed).
• A mob will immediately despawn if there is no player within 128 blocks of it. Note that this is a Euclidean sphere, not a cylinder from map top to bottom and not a taxicab sphere (which is more of a diamond). Example: A mob at 0/y/0 will remain at least 30 seconds (as above) if the player moves to 65/y/65 (real distance 91.9), but despawns immediately if the player moves to 91/y/91 (real distance 128.7).

Thanks a lot! I already read the spawn codes so now this is very helpful! But this makes it very hard to make...hmm, thanks again!
