That seems very unlikely! Most people reckon on a cruising consumption of around 1 L/Nm - regardless of the boat/engine - so more like double that. I don't know what engine it has but at full throttle a 200 HP 2 stroke will be burning close to 100 quid in petrol and oil every hour.
Bigger boat means:
- more expensive to store (realistically you'll not want to be launching and recovering a 9m boat on a regular basis especially with 4 grumpy children getting in the way!).
- larger engine so more fuel - more fuel means more tempted to refill at the dockside than tow it to a garage = significant premium
- larger engine probably more expensive to service / parts etc
- larger boat to tow (if this is what you plan) - more expensive on fuel, more restrictive on tow car, harder work to move etc.
All the 'silly things' like anchors, ropes, fenders, covers, etc will all be bigger and so add up to more initial cost or more replacement cost when the time comes.
