An undistorted-scale hydraulic model study was conducted to investigate the adequacy of three breakwater cross sections considered for use at Maalaea Harbor, Maui, Hawaii. Plan 1 was protected by 6-ton dolosse on both the sea side and beach side, whereas Plans 2 and 3 used 6-ton dolosse sea side and 7- to 10-ton stone beach side. Plans 1 and 2 used 1V- on 2H-armor slopes and Plan 3 used 1V on 1.5H-armor slopes. Based on results of model tests, it was concluded that Plans 1, 2, and 3 are stable designs for the maximum breaking wave heights that can be expected to occur for 12- to 16-sec waves at swl's of -1 and +4 ft mllw. Also, Plans 2 and 3 can withstand attack of 16-sec, 15.2-ft breaking waves at an swl of +6ft mllw and 16- sec, 16.7-ft breaking waves at an swl of +8ft mllw without experiencing significant damage.
