Tube molded into the hull

[mayhem]

Hi
Can anyone advise the purpose of a piece of plastic hose that has been molded into the bottom of the hull on my Fantasia 27.

It has small cuttouts in each section of the hull.

Is it just to allow any water to flow from one part of the hull to another?

Probably yes.  They allow water to flow and collect in the lowest part of the hull.  Your bilge pump pick up should be located there.
