Internal: If <target> is non-hostile you can dock. Enter the 'shed' (the small covered structure directly in front of you, often containing lockers) & at the back, to the right, there is a shield control panel available for you to hack using the craftable Security thingy. If you successfully hack this the ship's shields will be disabled for a time <5mins? Needs checking> (all the main shields plus most of the turret's shields on a warship). There's a similar panel elsewhere to disable turrets, I think.. but you probaby probably won't want to hack the Repair panel in the 'shed'! Shield hacking will significantly reduce the time required to board <target> if that's your objective, as you can immediately start reducing hull strength when you're ready rather than fighting your way through shields first..

A Rahanas freighter is an easy boarding target on paper only: its hull is so weak that a slight miscalculation or stray shot may destroy the ship with your marines onboard, & it has so few defences that its main asset other than its cargo (it's drones) are at great risk of being lost to Yisha's boarding demands (destroy Drone Bay). If possible choose a Sanahar over a Rahanas Container: the hull is stronger, defences are better & (slightly) more numerous & its speed & maneuverability is much improved over the earlier model. Once you have the technique, it's just as easy to board despite the slightly increased BR <Sparky please link to boarding pages>(see boarding guides linked here).
If you want the cargo
You can hack <target> using the Trojan drone, or board them. If you hack them be aware that ejected cargo containers have a 'lifetime'; if your pickup drones don't get there in time the looted containers will self-destruct.. so make sure you have a suitable cargo ship nearby & available before you start this procedure!

CHECK FIRST using your scanner & target information system to see if there's a market for the ware(s) <target> is carrying! If the wares are unsalable (currently eg (v4.00b2) Plasma Jets & Hailstorm) then unsellable (e.g. the weapon turret market is often saturated) then a lot of profit is lost immediately. HOWEVER you can still sell the ship with its cargo to a convenient shipyard to recoup at least some of the cargo's value* REMEMBER that you can always transfer excess unsalable unsellable wares to a ship that's going to be sold, provided it has an intact drone bay..
