In a written proposal distributed to councillors, the club said the ramp had a book value of $1.2 million and if properly managed, had the potential to make a profit from member boat-owner users and casual launch fees of $41,000 a year.
A share of those profits would equate to a 3.4 per cent annual return to the council from its one-third, $400,000, investment.
The proposal said two areas identified as potential sources of additional income for the club were installing a barrier arm for access to the launching ramp and increasing membership fees.
Non-club members were able to use the ramp under an "honesty system" but this was "not working with many boats being launched without the payment of a fee".
The club planned to install a card-operated barrier arm in the near future to overcome the problem.
The present senior membership fee of $120 a year was higher than that charged by most other fishing clubs nationally, and by similar social clubs in Hawke's Bay.
"It was felt a significant increase in senior membership fees would see many members resign, further decreasing income," the proposal document said.
Napier Mayor Bill Dalton told the meeting the council would deliberate on the club's proposal "and we will certainly consider what our involvement might be".
About 60 club members and supporters attended the council meeting, a turn-out Mr Dalton said was the largest number of people he had seen in the public gallery.
