On 10 December 1978 Holoholo went missing at sea, presumed capsized and sank with its crew of 10 people.
[1] Holoholo was built between 1959 and 1961 by E. R. Simmerer and launched in 1963 as a pleasure craft for Arthur F. Stubenberg, who had commissioned her.
On 15 September 1978 Stubenberg sold Holoholo to John Laney for $75,000 by multiple payments until the amount was reached.
The incremental flooding in the vacant lower decks could have destabilize the boat and cause her to capsize.
On 9 December 1979 NOAAS Townsend Cromwell picked up signals from the sea floor.
