(Q) What is the purpose a waterline on a fishing vessel,
why do naval architects make one up?
(a) For the crews safety, as soon as the waterline meets the water
then for safety reasons you have the maximum catch onboard your
vessel, you have used your maximum draught, what freeboard you have
left is for the safety of your crew (Q)
What is the purpose of the Summer/winter loadline on a Merchant
Navy vessel?
(a) For the safety of the crew also, the density of water changes
from port to port all around the world, some ports have fresh
water coming from rivers, you need to know the density of the
water in the harbour using a hydrometer (Instrument for checking
the density of water) (Fresh water is 1.000t per metre cubed and
sea water is 1.025t per metre cubed)
Remember salt water makes your vessel more buoyant, but coming
form salt water to fresh water, your vessel is going to sink because
fresh water is less buoyant.
