Over the past five or six years, and at first entirely on a trial-and-error basis, some of the main operators of charter-fishing in Kenya have pioneered a new and offbeat attraction: overnight expeditions in search of the Broadbill swordfish. Such a venture does not appeal to everyone. But those who have sampled it acknowledge that it gives the rich tapestry of life a whole new dimension.
Although initially this was a search-and-hope operation, there is no great problem nowadays in knowing where to start. It has become a demonstrable fact that they congregate and feed where undersea topography plunges to give substantial depth of water. So skippers will employ a G.P.S. to head for one of their favoured waypoints, where the ideal depth will be between 1500 and 2000 feet.
Boats will often aim to get lines in at dusk, when everybody can just about see what they’re doing, and a strike at that time is not wholly unknown. But this is strictly a night-fishing enterprise. Like the lion on the plains, the Broadbill – with its prominent eyes – has no difficulty in finding prey during hours of darkness. And again like the lion, this fish will tend to "switch off" during full-moon periods, so that in practice: the darker the better.
Techniques have evolved through a cumulative process of learning and experimentation. The old system used to be drifting, whenever the current was running at a convenient 3 to 4 knots, while keeping the boat lights on, reckoning that this would attract squid and thus bring in the predators. At that time, squid was regarded as the "only" bait.

Drifting at night is never comfortable. And squid, however preciously presented, is not vital when none is available, Broadbill have been known to go for a chunk of bonito, or for frigate mackerel, half-beak garfish, or any sort of small fish they are really not fussy. Moreover, when drifting with bait, problems with sharks’ can often occur, while bits of the bait tend to get nipped-off by snake mackerel or whatever.
It is now agreed here that the best method is undoubtedly trolling, at something like 4 to 5 knots. This obviously covers more ground and brings attendant benefits in contexts of comfort, safety and resultant strikes. And the professionals are now convinced that bigger fish will be hooked when trolling than through any other technique.
All agree nowadays that boat lights should certainly be off, so that (human) eyes can get adjusted to the darkness, while the hunting circumstances for this predatory fish will be untainted. Lights may of course be put on for a while at the trace-grabbing moment, but not until then. It is important that light-sticks be used when trolling, either in the lure or (more often) where the swivel is on the leader.
The broadbill is arguably the strongest fighter in the ocean, and an experience not to be missed. So far mainly small broadies have been caught off Watamu, (i.e. 30 – 70kg) but 4 or 5 in a night is not uncommon.
