The UK Coastguard standby SAR cabs do not have doppler/autohover capability and only a single winch.
They have the older intercom and simplex AFCS.
There is no major restriction on capability. Night jobs and/or very bad weather ops are not really a problem provided there is some sort of reference when operating below 45kts.
I do think that both the main and standby cabs are looking a little tired these days
