[6][7] Hornsea Mere is a centre for bird-watching and a tourist attraction offering rowing, sailing, boat trips and fishing.

[12] Initially, numbers 248 and 251 squadrons operated from RNAS Hornsea Mere with a headquarters at Killingholme.

[13] The RNAS base was located on Kirkholme Nab, a small 6-acre (2.4 ha) peninsula that sticks out westwards from the eastern shore.

The RNAS installed two Bessonneau hangars and two slipways from Kirkholme Nab which allowed a dozen seaplanes to be operated from the base.

[15] A number of brick buildings left behind by the RAF in 1919 are still in use today, employed by the boatyard and the cafe which operate there.
