Ventnor Coastguard Rescue Team and The Needles Coastguard Rescue Team were tasked to the northern shore near Cowes at 16:27.
Once on scene it was evident that a vessel – with 2 people on board – had gone hard aground on the rocks and mud.
A mud technician was deployed to ascertain the terrain for the team to head out to the area safely and obtain details and further plans.
With all occupants confirmed safe and well it was left and put at anchor to refloat with support from Cowes RNLI Lifeboat.

The yacht had called Mayday on VHF Channel 16. However, with the help of Ryde Inshore Rescue, it was ascertained that that all persons were safe and well and there was no damage to the vessel.
The vessel will await the next tide to float off.
