The 'William Allchorn' is 54 feet in length, weighs 36 tons, is constructed of wood using double-diagonal planking, and is almost certainly the largest beach-launched pleasure boat in service today.

She was purpose built as a pleasure boat in 1950, in Newhaven, East Sussex, by E. Cantell & Son. She is licensed to carry 100 passengers.

The 'Southern Queen' is 46 feet in length, weighs 27 tons, is constructed of wood in the clinker fashion, and is probably the largest vessel of this type of construction still in service in the United Kingdom, if not the world.

She was built by the Prangnell family, in 1950, in a barn at Westham village, not too far from Pevensey Castle, and was taken nearly two miles by road to her launching in Norman's Bay, some four miles east of Eastbourne. She is licensed to carry 72 passengers.
