I have been asked about portlights and pumps fitted to Margherita. The bilge pump Is a Whale Compac 50 and is mounted in a fixed portion of the cockpit floor/sole.  The outlet goes out to starboard, through the side of the cockpit (into the internal accessed stowage area) 90 degree bend then piped up to under the seat base and out through the side of the hull.

The portlights were supplied by Timage in UK and are chrome plated brass.  They do open but I seldom do as sealing them is a pain as the rubber seals are hard.  They are screwed to the cabin sides from inside the boat and the outside rim is dressed with a screw - on chrome trim.  They are shown on the Timage web site at http://timage.eu/marine/portholes-hatches/92-art8-round.html#/116-porthole-8c_chrome_12mm_spigot.  But I am not sure if they still do them.  They are also on Norfolk Marine's web site.  I have two different diameters Timage ref 8B00C and 8C00C.  I cannot access the boat to measure the dia at present - ask if you want me to and I will do it next month.
