Here is why the survey means NOTHING!
1. Ranger owners are seldom first-time owners. If they are, they probably don't use it much anyway.
2. Nitro owners are very often first-time owners. Nitro is priced aggressively.
3. More people complain if their '83 Escort won't start, than 2003 Rolls Royce owners under the same circumstances.
4. No one likes to admit that they're wrong, especially when there's money on the line. If you make a decision you regret, and it's your first of that item, you blame the manufacturer. After that, you have to accept blame. To avoid accepting blame, you admit to no problems.
5. On Ranger, people are paying extra over any other brand. Boston Whaler is no different.
6. Short of the actual engineering of the boat that determines handling and performance, the rest is all similar.
7. If a bilge pump in a Nitro fails, Nitro's are pieces of crap. If a bilge pump in a Ranger fails, Rule is a piece of crap (maker of bilge pump).
8. First time boat buyers are NOT overly-educated and don't understand boat setup (nor care).
So, in the end, Nitro is an entry-level priced boat (with the exception of the 9 series). Ranger's entry level boat is more expensive than the same size top-of-the-line Nitro.
I'm not saying Nitro is or isn't the best boat made, nor am I saying Ranger is or isn't. Ranger folks are brand loyal, Triton too. Skeeter has their loyal following as well.
If the owner of a Ford Powerstroke had problems and was sent a survey, he'd still answer favorably because "at least it's not a 'dodge or chevy'".
One thing that cannot be written off is that Nitro doesn't hold resale value very well. Another is, the 9-series is just plain HEAVY (good if you want strength, bad if you want speed).
