What the fleet has seen

The J Boats Tillotson Pearson J/109, as the fleet has seen it

Derived from the videos the fleet has analysed of this model. ▶ marks open the moment aboard.

The J Boats Tillotson Pearson J/109 is a fractional sloop designed by Alan Johnstone, built by J Boats Tillotson Pearson and J Boats since 2004, with a length overall of 10.7 meters, a beam of 3.5 meters, and a displacement of 4944 kg. It features a fin with bulb and spade rudder hull, and was later offered with a shoal draft keel option and a Volvo D1-30 diesel engine. Peter Gustafsson, known as "Mr. Blur," campaigned a J/109 for 15 years in international offshore regattas, including the Fastnet Race and Middle Sea Race, before transitioning to a J/111 and later a J/99.0:40 Gustafsson's experience highlights the logistical challenges of international racing, noting that shipping a 36-foot boat often faces delays, advocating for boats transportable by truck for flexibility.16:32 Safety requirements for regattas, such as the Færderseilasen, mandate equipment like two buckets with lanyards, a waterproof first-aid kit, and life jackets with crotch straps, which also serve as a baseline for family cruising.5:03
