more to the point, you need 1000hp if you have a 30 foot boat and 24 degree deadrise. Its just so impractal to have 500hp on a weekend cruiser or fishing boat, unless you have five or six mates to help pay for the fuel. As long as the boat has scuppers, foam flotation and a soft ride, it doesnt need to be 9m in length to get to the offshore fishing grounds. I think its more of an American ideal to have a massive boat with heaps of horse power. I have a picture of a 30 foot centre console with four 250 hp two strokes on it..........why? TWin or single deisels would be so much more economical and sensible. Not to mention more reliable. Speaking of small boat anglers just look at mackmauler he rides a 4.5m ocean cylinder RIB with a 50 hp honda. Hows that for small boat.
