All floors of the four-storey hotel were affected and 15 breathing apparatus, five main jets and two aerial ladder platforms were used to bring the fire under control.
The stop message came in at 04:30 with further reinspections expected today.
Group Manager Justin Harden said: ‘Teams worked hard in difficult conditions, particularly early on with challenging wind conditions. Crews adapted their tactics accordingly to manage this.
‘I’d like to add my thanks to crews from across the Island who worked throughout the night and to the crews from Hampshire who provided support and resilience.
‘This was a multi-agency effort and we were well supported by Isle of Wight Police, Isle of Wight Ambulance Service, Southern Electricity, Southern Water, Isle of Wight Council’s emergency planning duty officer, the Coastguard, the Environment Agency and South Central Ambulance Services Hazardous Area Response Team, all of whom helped deal with this situation and manage the wider considerations.
‘Whilst the site will be secured, areas of the hotel are structurally unstable as a result of the fire. I would now appeal for the public to stay away from the site for their own safety and so that reinspections can be carried out.’
The cause of the fire is not yet known but will now be investigated.
