roger blough on ais

[RTNerd]

Could be related to a low forward pilothouse-mounted antenna. Most boats have a much higher antenna mounted on top of a mulitstory aft deckhouse.

is there a reason why the blough does not always show up on the ais map until the last minute. many times I see her at the soo and try to catch her in Detroit about 24 hours later ansdshe is off the map
