useful ship commands:

'gr' is a command-alias to 'sailor gangway raise'.
'ga' is a command-alias to 'sec;sailor gangway $*;ship repair;gangway'.
'cruise' is a command-alias to 'sla;@cruise $*'.
'sec' is a command-alias to 'ship secure;console info condition'.
'sla' is a command-alias to 'ship launch'.

using these you no longer need to repair or mess with the gangway at all.
