*794 Opinion
In this case we consider the application of
Knight
v.
Jewett
(1992)
Facts and Procedural History
The basic facts are undisputed. On August 27, 1997, Rhodes took the Shannons 1 out on Lake Kaweah. Rhodes had owned the boat for just a few days. While out on the lake, Rhodes was driving when six-year-old Haley fell out of the boat. Haley’s mother, Connie, attempted to grab Haley as she fell overboard but was unsuccessful. Haley fell in the water and was apparently run over or somehow hit by the boat’s propeller, resulting in severe injuries to her arm. Haley was transported to a hospital and ultimately brought this suit.
On June 3, 1999, the Shannons filed a complaint against Rhodes alleging general negligence. The Shannons contend, among other things, that Rhodes negligently failed to make sure his passengers were properly seated before accelerating the boat. 2 The complaint alleged, in pertinent part:
*795 “Mr. Rhodes operated his motor-boat in a negligent manner, causing Haley Shannon to be thrown over board and seriosly [sic] injured by the boat propeller.
“Haley’s brother, John Shields, and sister, Samantha Shannon, were present and witnessed the serious injury to Haley, and as a result suffered severe emotional distress.”
Rhodes answered the complaint June 29, 1999, asserting the defense of assumption of risk, and filed a motion for summary judgment on January 27, 2000. Rhodes’s motion contended the doctrine of primary assumption of risk barred the Shannons’ claims, and, alternatively, Rhodes attempted to disprove causation and sought summary adjudication on the separate issue оf whether Haley’s siblings could prove a claim for emotional distress. The Shannons timely opposed the motion, arguing primary assumption of risk did not apply and that there were disputed questions of fact regarding causation and emotional distress damages. After announcing its tentative decision to grant the motion for summary judgment, the trial court heard argument on March 1, 2000. The court issued its order on March 1, 2000, granting the motiоn on the grounds that Rhodes owed Haley no duty of care because the doctrine of primary assumption of risk applied. Rhodes filed and served an amended judgment April 12, 2000. The Shannons timely appeal.
Discussion
I
Did Rhodes Owe Haley a Duty of Care?
A. Standard of Review
A defendant moving for summary judgment must show either (1) that one or more elements of the plaintiff’s cause of action cannot be established, or (2) “that there is a complete defense to that cause оf action.” (Code Civ. Proc., § 437c, subd. (o)(2).) “[T]he defendant has the initial burden to show that undisputed facts support each element of the affirmative defense.”

Southern Cal. Edison Co.
(1997)
B. The Nature of the Activity
Appellants contend that the trial court erred because the primary assumption of risk doctrine should not aрply to bar the claim of a passenger in a ski boat being used for a ride around a lake. Appellants argue that a passenger riding in a boat simply is not engaged in the type of activity the Knight court intended to reach with the doctrine of primary assumption of risk. Respondent contends that recreational boating is a “sport” within the meaning of Knight. We conclude appellant has the better view.
Generally, of course, “persons have a duty to use due care to avoid injury to others, and may be held liable if their careless conduct injures another person. (See Civ. Code, § 1714.)”
(Knight, supra,
Our analysis begins by examining with what activity the
Knight
court was concerned. In
Knight,
the court came to the commonsense conclusion that when two people are playing a sport together one should not be liable to the other for injuries sustained while playing that sport absent some recklessness or intentional misconduct.

2. Other Boating Cases and Out-of-state Authority
Respondent relies on
Ford,
to argue that the Supreme Court has explicitly considered boating a “sport.” In
Ford,
however, the court explicitly used the language “noncompetitive
but active
sports activity” in applying the doctrine to waterskiing.
(Ford, supra,
*799
The other California authorities relied on by respondent to assert that courts have applied the doctrine to cases in which plaintiff was a passenger in a recreational boat are likewise distinguishable. In
Stimson
v.
Carlson, supra,
Similarly distinguishable is out-of-state authority respondent points to in which the participants are clearly engaging in activity of a physical sort or where the court applies the assumption of risk doctrine based on the plaintiff’s subjective knowledge of the risk involved, which is not the duty-based doctrine applied in California. (See
Marchetti
v.
Kalish
(1990)
3. Chilling Effect
We next address respondent’s vehement assertion that recreational boating would be seriously curtailed if primary assumption of risk were not available to those engaged in the activity of boating. We agree that whether the application of the assumption of risk doctrine will have a chilling effect on the vigorous involvement in the activity is one of the factors our Supreme Court has instructed us to consider, and we must point out that we do not hold that primary assumption of risk will
never
be applicable in the boating context.
(Knight, supra,
3 Cal.4th at pp. 318-319.) Under the facts of this case, however, we do not agree that imposing a duty of care on respondеnt
*800
will create a “chilling” effect on the activity of recreational boating. In
Ford, supra,
Moreover, on a commonsense level, we simply cannot conclude that the use of the boat in this case reasonably implicates a “sport” within any understanding of the word. There is nothing in this record to indicate the boat here was anything morе than a mode of transportation. Nothing about the type of boating engaged in here required participation by the passengers, there is nothing competitive or physically challenging about riding in the boat, and it certainly requires no special skill nor physical prowess to do so. Just because the means of the activity (the boat) may at other times be used for sporting purposes does not autоmatically transform the boat itself into a “sporting activity.” Certainly no one would consider being a passenger in a car on the way to work a “sport,” and yet we could all agree that stock car *801 racing is a sport. Both involve cars; one is a sport, one is not. Nor are we convinced, as respondent implies, that the fact some activity is done “for pleasure” automatically transforms it into qualifying for the protections of the doctrine of primary assumption of risk. Rather, as we previously explained, whether a sport or activity qualifies for the protections of the doctrine of assumption of risk requires a more thorough analysis than merely deeming it recreational or pleasurable.
We therefore conclude, under the facts of this case, that where a driver of a boat takes passengers out on his boat for a simple ride around a lake, the nature of the activity is not one that brings it within the Knight rule and therefore the doctrine of primary assumption of risk does not apply. 4
II
Applicability of Harbors and Navigation Code Section 655, Subdivision (a)
Appellants also contended in opposition to the motion for summary judgment that Harbors and Navigation Code section 655, subdivision (a) creаted “prima facie evidence of reckless or negligent operation” and therefore precluded summary judgment. Our conclusion that a duty of care was owed by Rhodes to Haley under the facts of this case makes resolution of whether or not Harbors and Navigation Code section 655, subdivision (a) creates a duty greater than may otherwise be imposed under
Knight
unnecessary. (See
Cheong

Antablin
(1997)

Notes
Though Connie Shannon’s 15-year-old son John has the last name of Shields, we will refer to the family as the Shannon family when referring to apрellants collectively.
There is no dispute over the facts relevant to deciding the legal issue before us, though the parties do disagree over each other’s generalizations of the facts. Along those lines, the parties include extensive details of Rhodes’s alleged negligence; however, neither we nor the trial court decides whether Rhodes was in fact negligent (i.e., whether he breached a duty of *795 care). Instead, the legal question is whether a negligence claim against him is barred as a matter of law (i.e., whether he had a duty of care). We do not, therefore, include every “disputed” factual detail regarding his alleged negligence. To the extent disputed facts are relevant to Rhodes’s claim below that he established a lack of causation as a matter of law, we discuss them in that portion of the opinion.
Respondent emphasizes that boating involves speed, rapid acceleration, sharp turns, choppy waters and other potential hazards and obvious risks, including the risk of falling overboard. However, regardless of the “risks” that may be inherent in riding in a boat, the existence of risk does not automatically call for the application of the doctrine of assumption of risk. Rather, unless being a pаssenger in a boat is considered by this court as the equivalent of being a participant in a sporting or recreational activity covered by
Knight,
then assumption of risk simply does not apply and the inherent “risks” of the activity play no part in the question of whether a defendant can be liable for his negligent activity. Likewise, respondent’s reliance on spectator cases is similarly distinguishable because, once we conclude an activity is not a sport to which the doctrine applies, the rationale of the “no duty” analysis as applied to, for example, spectators at a baseball game, is simply inapplicable. (See
Knight, supra,
Because we conclude the boating at issue here is not a “sport,” we need not address appellants’ argument that primary assumption of risk cannot be applied to a six-year-old child. We also recognize that Rhodes contends that Haley’s mother was actually responsible for ensuring Haley did not fall overboard. That may be so; but that is a factual decision left to the trier of fact to sort out under comparative fault principles.
