For Kenan Knieriem, a good day was golf in the morning, sailing in the afternoon and soccer at night, says his son, Kenan "Keno" Jr.

The 58-year-old successful investment adviser was enjoying one of his favorite pastimes — a day out on his boat, fishing — when he went overboard Saturday morning and was lost at sea some 13 miles south of Hawaii Kai. His body has not been found.

He was accompanied on the boat trip by his wife of two weeks, Debi Ozawa, her acquaintance Amalia Johles and their new home’s interior designer, Rosina Ho.

"He loved the sea, loved fishing," said his manager and friend, George Kaluhiokalani, director of Merrill Lynch Wealth Management in Honolulu. "He had a passion for the business. He will certainly be missed."

Knieriem, institutional consulting services adviser, would have been with the firm for 30 years in November.

"He was probably one of the brightest people you’d know," Kaluhiokalani said. "He had a positive attitude, knew the industry very well. He was a charter financial analyst, very smart.

"He always did things right and had great integrity," he said.

Born April 29, 1953, in Sendai, Japan, Knieriem went on to attend the Naval Academy in Annapolis, Md., rose in rank to Navy captain and retired as a reservist after 20 years.

"He’s a big influence in my life and 99 percent of my friends," said 27-year-old Keno Knieriem, a Navy salvage engineer who also attended the academy and played soccer there.

Knieriem arrived in Hawaii in 1976 while in the Navy and never left.

"He felt at home here," Keno Knieriem said. "He met a lot of people who took him in."

They became his family, and "I have a hanai grandpa," he said.

The senior Knieriem coached soccer at Punahou and with the American Youth Soccer Organization, and continued to play soccer in Hawaii in the men’s league.

Five friends of the younger Knieriem are flying in from the mainland "more for my dad than for me," he said. "I think he’s been a father figure to a lot of guys."

He recalls how his father would buy better Christmas presents for his friend Joey, who lost his father at a young age.

"Now I understand," he said.

Knieriem’s wife and the other two women aboard the motorboat Ikaika spent most of Monday recalling details of the incident with the Coast Guard, which has opened a routine inquiry.

The Coast Guard said it received the man-overboard notification at 8:50 a.m. Saturday and searched for 10 hours, covering 117 square miles.

Lt. Leigh Cotterell said the Coast Guard will go through the elements, find the facts, the human factors involved, any equipment failure and anything that was "a part of the causal chain that led to the accident or incident."

At Annapolis on Saturday, a moment of silence will be observed at the Army-Navy soccer game, Knieriem said.

Knieriem is also survived by a daughter, Katie, brothers John and Guy, sister Jane Bass, and the mother of his children, Judy Knieriem.

A celebration of life will be held 10 a.m. to 4 p.m. Saturday at Lanikai Beach. A paddle-out will be held at 10:30 a.m.

Casual attire is requested.
