The wreck lies on its port side and what you will see are the inside timbers of the ship’s hull. There are nine dive stations at points of interest around the wreck. Follow the shot line to the seabed, and the site is 20m south west of the shot line – there is a lead line you can follow from the shot to seabed station 1. Each seabed station has an arrow pointing to the next station.
Interactive plan of the wreck
This is a 3D version of the structural site plan of the wreck of HMS Colossus, off the island of Samson in the Isles of Scilly. HMS Colossus was a 74 gun warship built in 1787 at Gravesend and wrecked in 1798.
Each colour represents a different structural element of the vessel.
