Crew on board Royal Navy minehunter HMS Shoreham have been making the most out of their time while delayed in Porto, Portugal.
While the Sandown-class minehunter was waiting for the weather to improve, some of the crew decided to make use of the waves and enjoy the day surfing.
In a tweet, HMS Shoreham said they were "not normally fans" of big waves.
The tweet went on: "We're still in Porto waiting for the weather to improve.
"But thanks to the Royal Navy & Royal Marines Charity we were able to enjoy a day surfing these while we wait for the weather to improve."
In August, HMS Shoreham and HMS Brocklesby began their homeward-bound 6,000-mile journey from the Gulf after a three-year mission to keep sea lanes there open.
The pair are the latest ships to complete an extended stint in Bahrain – a mission Royal Navy minehunters and their crews have conducted for 15 years.
HMS Brocklesby arrived back at Portsmouth naval base on Friday and, along with Shoreham, on her return, will undergo a period of maintenance before rejoining the fleet in 2022.
As well as the surfing, the sailors who are "speed demons" were able to take part in some "all friendly and not at all competitive…" go-karting.
