There's an article at MarineInjuryLaw.com -
Coastguard Negligence: When Seafarers Are Better Off Amongst The Flotsam - that's got an interesting bit:
"Lawsuits against the Coast Guard for injury to persons or property damage generally must be brought under a federal statute known as the "Suits in Admiralty Act." The Suits in Admiralty Act is a limited waiver of the federal government's sovereign immunity from civil lawsuits in certain maritime contexts. In other words, it empowers parties injured by the Coast Guard to demand compensation. Additionally, the Suits in Admiralty Act simplifies rules regarding where and when an injured plaintiff may file a civil suit concerning a government owned ship.
While the Suits in Admiralty Act provides those injured at sea with some important rights, it also lays out certain specific limitations. For instance, Coast Guard negligence suits under the Act must be brought within two years of the incident in question, and claims under the Act are tried without a jury, making a skilled maritime attorney who fully understands the law an especially important asset to injured plaintiffs."
No jury, eh? Interesting.
