Moorsom entered the Royal Navy College in Portsmouth where he was awarded a first medal and three prizes for mathematics.

[5] His other brother William Scarth Moorsom left the navy in 1832 and became a successful railway engineer after training with Robert Stephenson.

It was found that the Fury had fired twice as many mortars as any other boat and that this was due to the fitting which Moorsom had devised.

Ariadne had been a problem vessel after she was converted into a corvette with the addition of a quarterdeck to her original frigate frame.

This increased her draught and made her difficult to manage, however Moorsom redistributed the storage and not only reported that she was now seaworthy, he sailed her around the Cape of Good Hope to prove the point.

He was briefly an acting Commodore in Mauritius, but in 1825 he served for two years as the captain of his father's flagship HMS Prince Regent at Chatham.

The portrait above is taken from the commemorative painting where he can be seen behind the head of Joseph Sturge of the Anti-Slavery International, who organised the conference.

He died at Russell Square in London after becoming a vice admiral in 1857 and having fathered a large family with his wife Mary Maude of Silaby Hall in Durham,[1] including the politician James Marshall Moorsom.
