About NZBMC events
Events are split around the lower South Island during the winter months, the 2016 season comprises of eight rounds kicking off at Lake Dunstan and Roxburgh Gorge, then Lake Te Anau, Lake Benmore, Timaru Harbour, Oamaru Harbour, Lake Waihola, before the season wraps up in Invercargill on the Oreti Estuary.
Events consist of two main sections - nominated speed time trial and a speed race, depending on the hosting club these can be combined into single or split into two separate races. Some clubs also host other events such as water ski racing or break the speed race component into two heats.
The nominated speed event requires competitors to nominate a speed prior to the start of the race which they must try and stick to as closely as possible over a number of laps, total race distance normally around 50km. The course is measured by officials using GPS equipment and a lap time calculation is performed based on the speed nominated by each competitor, points are then given based on the lap time of each boat during the race. The greater the deviation from the nominated speed (either higher or lower) the more points given, after the race the competitor with the least points is the winner. The key is consistency to desired speed not overall speed and this event is always highly contested by fishing and cabin boats so if you are looking for an event to start in this is for you. No GPS equipment is allowed in competing boats.
Speed event is as the name would indicate at typical speed race. Boats are split into seven classes of depending on engine size and hull configuration (refer to more info tab for class details). Catering for every craft from fishing, leisure, runabout, ski and specific race boats. This segregation provides opportunity for boat owners who would not have normally considered participating to enter a speed event and then allows for some very close racing within each class.
All boats regardless of class start together in a rolling fashion under the control of the start boat, each class then is required to complete a certain number of laps depending on lap length. Faster classes are required to complete more laps than slower resulting in most classes finishing racing around a similar time. The distance completed by the faster classes is approximately 100km stepping down to the lower classes completing approximately 60km. First boat home honours can be won by boats in lower classes due to the lesser number of lap required to complete.
Cabin boats are eligible to enter one class below their designated engine rating, while engines modified away from manufacturer specification and specific race boats are to race up one class from the designated engine rating. This again provides close racing within the classes as a cabin boat with 200hp will be competing in the same class as a runabout with 150hp.
All boats are scrutineered before each event to ensure they meet safety standards and have appropriate equipment on board. (requirements are available). Safety boats are present out on the course with a diver and paramedics on standby onshore at each event.
