"The guys who took off fast would pay later in the race ... apart from Great Britain."
"While we were gaining very strongly we had emptied the tank during the last 50 metres," Mackintosh said.
The 22-year-old Lindisfarne College old boy was thrilled his crew did equal best of the New Zealand crews at the under-23 world champs. Jack Lopas and Ollie Maclean also won silver in their men's double scull final.
"Today's silver is the highlight of my international career to date. When you consider the other members of this crew are just 19 we've got plenty of promise," Mackintosh said.
Last year Mackintosh was in the New Zealand coxless four which won bronze at the under-23 world championships in Poland. Just as he did after those champs Mackintosh today heaped kudos on the Hawke's Bay development systems.
"Hawke's Bay has good coaching programmes. The technical work put in on the Clive River has set me up well," Mackintosh said.
Since leaving Lindisfarne College Mackintosh has represented the Southern Regional Performance Centre and the Canterbury club.
