Beth is a 15.5ft sailing boat designed by Iain Oughtred. She was launched in 2007 after a two year build. Iain Oughtred's original "Tammie Norrie" design was a 13.5ft boat with the option of a lug yawl or sloop rig. Paul scaled the boat up 10% from the original design and changed the rig to a gaff yawl instead of lug sail. Paul was also keen on a boat which was small and light enough to row home when the afternoon wind fails.
Iain Oughtred designed Tammie Norrie as an open boat with a yawl rigged lugsail. Paul wasn’t keen on the lugsail and he knew Iain had another, bigger, design for a gaff rigged yawl. Iain was also working on a version of the Tammie Norrie design that had been scaled up 10%, so Paul went ahead and bought the Tammie Norrie plans and then proceeded to scale them up 10% and modify the mainsail to a gaff himself.
