How much would a raft sink if a woman stepped onto it?

A raft is made of solid wood and is 2.31 m long and 1.59 m wide. The raft is floating in a
lake. A woman who weighs 158 lb (71.6676 kg) steps onto the raft. How much further into
the water does the raft sink?

Hint 1:You do not need the thickness of the raft or the density of
the wood to solve this problem.
Hint 2: The answer is between 1.40 cm and 2.30 cm.

∑F = 0
W - F_buoyancy = 0
W = F_buoyancy
m_woman*g = ρ_water*g*V
m_woman = ρ_water*A*h
h = m_woman/ρ_water*A = 71.6676 kg/1000*2.31*1.59
h = 0.0195 m
h = 1.95 cm

Professional Whitewater Rafts developed two things: do not rollover, and no punctures. Properly constructed commercial raft Score Whitewater bounces most boulders, and keep a steady course in a remarkably turbulent water. In most places, you can float through the Whitewater Rapids forward, backward or even sideways, and this is only part of the fun. If you do this in a canoe, kayak or raft flimsy pool, the results can be disappointing, to say the least.

You wear Whitewater PFD (personal flotation device). It's amazing how many people who take the Do-It-Yourself Approach to rafting or do not use the right kind of raft, or do not wear a PFD. Walking on a commercial rafting trip, wearing a PFD is not an option, it is a requirement.
