Fiskars Buster X boat - Yamaha F70

Buster X is a recent hull* from Fiskars. It is a medium size aluminium hull ( 5,25m) that holds 6-8 people at 22-23 knts cruise speed( max 32). It is a very robust construction without fancy ( heavy) plastics and decoration, thus needing a small engine ( 70-80 hp). It is enough for waterskiing / wake but will be a bit slow/light for a strong slalom skiier maxxing at 30 knts with a F70. The hull is very safe with very predictable behaviour and great wave/wake crossing making it an ideal platform for a family with children.
Yamaha F70 is a great combination with the hull, it is very very silent and sober. Fuel consumption around 23 l/hour at 32 knts. 14-15 l/hour at cruise speed.
( I am still wondering why would someone want a heavy bulky 5 m boat that needs a 125 hp minimum to cruise at same speeds and take 1/3d more gasoline....)
* It has just been modified in 2013 by Fiskars with a bulkier bridge
