Hi there i've got great news for you all i was building a large raft when i discovered something i wish that it stays in any of the next versions
i discovered that :
I CAN KEEP THE SHARK AWAY AND PREVENT IT FROM DAMAGING A VERY LARGE AREA OF MY BOAT!!!
am i kidding or cheating?
build a new world and keep it a world for just trying this
this is totally an insane adventure
just hack your second profile using cheat engine > http://www.cheatengine.org >
then try this
you have nothing to loose
build a large raft as you would like (largest 15*15 foundations) then go to the front-left edge of your raft
now build one line with the length of 18 to 20 foundations (the ground floor) in each of the two out directions of this edge
finally kill the shark once
now the shark will stay in a very small circle -Pretty,isn't it?-
even if it attacked all of it's attacks will be on the two lines that blocked it's moving
watch out if you built the raft to block the shark then matching the two lines from the outside will cause the game to get crashed
