A 90 kg man has a raft 366m wide which weighs 2600kg He prop

A 90 kg man has a raft 3.66m wide, which weighs 2600kg. He proposes to use it as a float for diving practice. When the man is standing on the centre of the raft, the righting arms are: The freeboard of the raft is 0.30 m. What heel angle will he produce if he walks to the edge of the raft. 1.83m from the centreline? Is this a good raft for his purpose? (To answer this question, determine the freeboard on the low side of the raft when he is standing on the edge).

Solution

GZ = sin (GM + 1

2

BM tan 2

)

= sin (1.6+3.7 tan 2

)

Heel GZ

15 ° 0.070 m

30 ° 0.204 m

45 ° 0.229 m

60 ° 0.030 m
