Broward Marine, Inc. appeals from a partial summary judgment finding it liable for conversion of appellee’s vessel. We reverse.
In May, 1967, appellee Bernier brought his yacht, “the Dagon” (a 14 ton 1933 “classic” gas screw documented vessel), to Broward Marine for storage. Subsequently in 1974, the yacht was hauled from the water and placed in dry dock storage. It remained in this state for approximately six years during which time Mr. Bernier failed to pay any storage bills. Finally, in April, 1980, Broward Marine resorted to self-help. Claiming a valid possessory lien under sections 713.58(1)1 and 713.60,2 Florida Statutes (1983), Broward Marine sold *869“the Dagon” pursuant to section 85.031(2), Florida Statutes (1983).3 Thereafter, Mr. Bernier instituted suit, alleging that the sale constituted a conversion. He asserted that Broward Marine erred by not proceeding under federal admiralty law. The trial court agreed, holding that 46 U.S.C.A. § 975 (West 1975)4 preempts the operation of section 85.031(2). Consequently, the court granted partial summary judgment finding that Broward Marine is liable in damages to Mr. Bernier.
On summary judgment, “the movant must show conclusively the absence of any genuine issue of material fact.” Wills v. Sears, Roebuck & Co., 351 So.2d 29, 30 (Fla.1977). “[T]he movant must prove a negative — the nonexistence of a genuine issue of material fact.” Ibid. “[I]f the evidence raises any doubt on an issue of material fact, or is such as will permit different reasonable inferences bearing on the existence of such an issue, summary judgment is not proper.” First Mortgage Investors v. Boulevard National Bank of Miami, 327 So.2d 830, 832 (Fla. 3d DCA 1976). In the case at bar, the extended period of dry storage coupled with other evidence about the dismantling of the ship’s engine raised a reasonable inference that “the Dagon” had become a “dead” vessel, i.e., unnavigable, removed from navigation or commerce and, thus, outside the ambit of 46 U.S.C.A. § 975. See generally, Murray v. Schwartz, 175 F.2d 72 (2d Cir. 1949); Frank B. Hall & Co. v. S. S. Seafreeze Atlantic, 423 F.Supp. 1205 (S.D.N.Y. 1976); Buck Kreihs Co. v. United States, 427 F.2d 770 (Ct.Cl.1970); 7A J. Moore and A. Pelaez, Moore’s Federal Practice ¶ .230[1] (2d ed. 1983). Since the movant, Mr. Bernier, failed to negate this inference, he cannot prevail on a motion for partial summary judgment.
Accordingly, we reverse and remand for further proceedings consistent with this opinion.
