Hi Harry,
Now I see! The narrow pipe was invisible on the earlier photos.
You are right. The small bore pipe is non-standard and I have no idea of its intended function. Is there a matching pipe to port?
I can only suggest you follow Perry's advice and try and get some photos of the area beneath the cockpit sole and above the hull and report further on what you find.
My (complete) guess would be that someone decided the boat needed a permanent bilge pump fitted. However, there should be no reason for needing that. A SeaHawk should be bone dry in the bilges, unless you accidentally spill something, the hull is damaged or fittings are not sealed properly.
The only time I see any water in my bilges is after sleeping aboard on cold nights, when any condensation caused by my body heat (or the rice I'd been boiling for last night's curry or mugs of tea) trickle down into the bilges - but a single wipe around with a dry cloth is sufficient to cope with that.
