4. Widebeam - Wikipedia

   en.wikipedia.org/wiki/Widebeam

   From Rickmansworth, a boat may travel north up the Grand Union, but at Leighton Buzzard there is a lock that is only 3.81 metres (12 ft 6 in) wide. So any boat with a beam of 4.22 metres (13 ft 10 in) able to navigate canals and rivers in and around London will be unable able to proceed further north.

   The key distinguishing feature of a narrowboat is its width, which must be less than 7 feet (2.13 m) wide to navigate British narrow canals. Some old boats are very close to this limit (often built 7 feet 1 + 1 ⁄ 2 inches or 2.17 metres or slightly wider), and can have trouble using certain narrow locks whose width has been reduced over time because of subsidence.

9. Laser (dinghy) - Wikipedia

   en.wikipedia.org/wiki/Laser_(dinghy)

   At regattas, boats are not measured, but rather inspected to ensure conformity with the rules. [7] The Laser hull is 4.19 m (13.75 ft) long, with a waterline length of 3.96 m (12.99 ft). The hull weight is 59 kg (130 lb), which makes the boat light enough to lift onto a car-top rack. [8] The various sizes of Laser are all cat-rigged.
