Maritime enthusiast Stan Fraser, 41, spent six years building the scale replica of the vessel behind his home, reports The Scotsman.
But Highland Council has now warned Mr Fraser that the structure requires retrospective planning permission.
He said: "I'm worried that if I don't get planning permission all the hard work will be down the drain."
The father of five had also been planning to install a working foghorn and lights to twinkle from the portholes.
AAHHH isn't that sweet!
