TheBoat canceled its' 6:30 a.m. departure from Kalaeloa this morning and its 7:35 a.m. departure from Aloha Tower.

Kalaeloa riders were transported to Aloha Tower via the F-shuttle bus, but no shuttle service was available for riders from Aloha Tower.

TheBoat also canceled its 6:15 p.m. departure on Monday from Aloha Tower.

The three cancelations are the first since May 28 when the Melissa Ann was briefly taken out of service to check sensors on the vessel's starboard main engine after it displayed an alarm.

Prior to that point, TheBoat had been running at 98 percent efficiency over the past four months.
