OK, here is another layman's question.
Here is a quote from an online post:
"By the time a boat reaches 16, 000 lbs. or around 36 feet, it is approaching the limit where a gas engine can power it efficiently"
I don't really care about the numbers, whether it should be 36' or 40', but I don't fully understand the "efficiently" part.
Let's say I have a gas engine rated at 300hp. Whether I use it to push a 5000lbs boat or 16000lbs, why does it make any difference? The heavier boat is just going to go slower at the same rpm, right? If I don't care about the speed, where does it "inefficiency" come from?
I understand if I want to push the two boats at the same speed, of course the heavier boat will require more RPM on the same engine, hence more wear and tear. But suppose I always drive the two boats at the exact same RPM, will there be difference as the engine life? Wear and tear etc?
