Quick addendum:

LEYTE was lost during a typhoon in the San bernadino Straits, 26 Sep 1905 with only 9 survivors.

I find the following launches mentioned in service during the 1904 fiscal year:

Customs: launches SEA GULL, SCOTER, HARBOR NO. 2 and HARBOR NO. 3
Constabulary: launches ANTONIO and CAPTAIN CLARK
Police: launch BUCKEY O'NEIL
Quarantine: launch MERCURY

This is probably only a small percentage of what was actually out there, too.

best regards,
