Blow out with compressed air would be the way I would do it

No all solid Conduit.
This can be a problem when Ribbing in Really Rough weather...especially if you get one wrong and ship some Briney ....or on a mooring (uncovered) in really heavy rain for long periods when it can rundown control cables into said conduit.
The solution is to extend the "Witches Hat" via a sleeve (or suitable tubing) ....which then raises the point of entry,or indeed may seal it...and if you can do it in the case of a sleeve so that you adjust the angle rain can't run down either.....this is something I've seen on some Ribcraft Ribs but not all

As for pumping any residual water out... (which would obviously settle at the lowest point and this might be helped by Tilting the Boat up) an industrial strength water vac might sort if you improvise a nozzle to fit into it....or a better option I think it may be better idea to try blow it out (from the consul end again tilted)with a high pressure airline which would also dry it out

To be honest i dont think you would move alot of water with a high pressure airline ...........reminds me of blowing down the combine harvester after harvest ,if you used compressed air you would hire in a road compressor to get loads of volume at a high ish pressure ,would certainly sort your underdeck passages ,,,,,,However in latter years just picked up on the best of the modern ..Leaf blower ,loads of volume at higher than atmospheric pressure ,reckon that would blow it out ???

No? Not even helping it down hill?
.....The leaf blower idea is not a bad oneCertainly works on a Cricket Pitch!
...It would help to have a seal of some kind whatever you'd use but a Big leaf blower (I've got a Backpack model) does pack a punch!...Best option is of course is seal it off properly in the first place!

Cheers guys, leaf blower, compressed air, neither of which I have!

Is there no merit in sucking out with some sort of hand pump and length of polythene tubing? besides, I need to get this to the entry hole in the console which is as tight as a gnat's chuff. The witches hat is all sealed up, as best I can, but it will still leak if submerged.

Probably worth a try with a thin house. A bulb type fuel transfer pump might do it and if it doesn't, it's only a few quid down the pan.

The stirrup type pump sucks which you pump the boat up with if you have one
