The helicopter was not likely sitting on the pad, engines running and ready to go. While it would have fueled, prepped and ready, the crew would have to scramble, board, go through their startup and head to the crash site. Probably a 10-15 minute process before initiation of the search itself. By then the plane would have sunk but for random smaller pieces of debris.
The boat on the other hand (speculation) may have already been out on patrol and close to the crash location to start with. Who says the boat just didn't happen to be at the right place and right time to quickly come across their survivor. Likewise the helicopter may not have been in an ideal spot at the start of their search to quickly pickup their survivor. It was dark, over water with swells. There may have been many pieces of debris to examine.
You seem to have an awful high and mighty attitude toward the rescuers for someone who sees the world from the perspective of a computer operator observing the world safely from 37K feet. Particularly when judging highly trained and skilled professionals who regularly pluck people from oceans under all types of conditions for a living.
This is the timeline
01:40 USGC informed of the pending crash (aircraft at about 600 ft at this time)
01:45 last ADS-B contact at 50’
02:51 first pilot picked up by HFD boat
02:57 second pilot picked up by USCG helicopter
The boat didn’t happen to be in the area, “took approximately 30 to 40 minutes to get to the scene”
“The Hawaii Department of Transportation’s Aircraft Rescue Fire Fighting boat also responded and took approximately 30 to 40 minutes to get to the scene as they navigated through a debris field which was approximately 1.25 miles wide.
HFD spokesman Capt. Malcolm Medrano said the fire department’s Air 3 helicopter assisted as the ARFF boat crew rescued one of the pilots, 50, from the water at 2:51 a.m.
The rescue boat took him to the end of Lagoon Drive where Emergency Medical Services personnel treated him for a head injury and multiple lacerations. He was then taken in serious condition to Queen’s Medical Center.
At about 2:57 a.m., the Coast Guard’s Dolphin helicopter hoisted the other pilot, 58, out of the ocean and airlifted him to Queen’s.”

Please have a look at the video in this report, in the lower left hand side as the show the crash areas the next day looking back towards shore you can see the large white building in the left hand side near the beach, that is the hanger of USCG Barbers Point on Coral Sea Road where the helicopter came from, just next to it is the threshold of runway 29 at Kalaeloa Airport.
