Dee Why was one of five broadly similar hydrofoils, being of type PT50.
Dee Why was the third hydrofoil to enter the Manly fleet and after the
retirement of the Manly, was one of three hydrofoils to be operated by
the Port Jackson company.
Dee Why figured in a an incident in 1972 whilst she was being serviced
at Berry's Bay. At one stage it had been suggested that the only thing
that the hydrofoils were good for was towing water skiers. The workmen
decided to try this out much to the amazement of the waterside
residents. Several rang the Port Jackson company to discover what was
going on. Not surprisingly, the experiment was not repeated.
Dee Why was a relatively young vessel when she was retired. She was a
victim of the prohibitive cost of running and servicing the hydrofoils.
Each hydrofoil cost more to maintain than the aging Baragoola and North
Head (consider that both these ferries carried 1,200 passengers each
and you can understand the economics involved). Wharf crew who took in
the ferries could not berth a hydrofoil and hydrofoils needed more
wharf crew than the big ferries did. More than once a hydrofoil's crank
shaft broke (this happened with all the PT50's) requiring the
deckhouse, flooring and engines to be removed to replace it - then
having to put it all back together. Fuel costs were also higher than
the larger ferries.
After being retired from service in 1985 Dee Why was scrapped at
Homebush Bay in 1988. The aluminium retrieved from the wreck was sold
