de OSR cat 1 regels (waarvan de driehoek-regels vast zijn afgeleid) zeggen:
3.23 Bilge Pumps and Buckets
3.23.1 No bilge pump may discharge into a cockpit unless that cockpit opens
aft to the sea.
3.23.2 Bilge pumps shall not be connected to cockpit drains. (OSR 3.09)
3.23.3 Bilge pumps and strum boxes shall be readily accessible for
maintenance and for clearing out debris
3.23.4 Unless permanently installed, each bilge pump handle shall be
provided with a lanyard or catch or similar device to prevent accidental
loss
3.23.5 The following shall be provided:
a) two permanently installed manual bilge pumps, one operable from
above, the other from below deck. Each pump shall be operable
with all cockpit seats, hatches and companionways shut and shall
have permanently installed discharge pipe(s) of sufficient capacity to
accommodate simultaneously both pumps
f) two buckets of stout construction each with at least 9 litres (2 UK
gallons, 2.4 US gallons) capacity. Each bucket to have a lanyard.
maar aan toch lijkt het me beter een eigen afvoer voor de lenspomp te hebben, boven water.
en nauurlijk 2 "stout buckets". Geen betere pomp dan een bange man met een grote emmer
