Quinn appeals from the District Court’s pre-trial ruling that he lacks standing to contest the search of his fishing vessel. We reverse.

Quinn had a legitimate expectation of privacy in the place searched (his boat), giving him a basis to charge that the search invaded his Fourth Amendment rights and to call for a judicial determination of the validity of this charge. See United States v. Salvucci, 448 U.S. 83, 91-92 , 100 S.Ct. 2547, 2552 , 65 L.Ed.2d 619 (1980); Rakas v. Illinois, 439 U.S. 128, 138-40, 143 , 99 S.Ct. 421, 427-28, 430 , 58 L.Ed.2d 387 (1978).

This legitimate expectation of privacy was based on the conjunction of the following:

(1) His ownership of the boat.

(2) His possessory interest in the marijuana seized, arising from his joint venture with Hunt for the smuggling of marijuana from the west coast of Colombia to Quinn’s ranch in Humboldt County, California. Ownership of both the place searched and the item seized conferred standing in pre Rafcas cases. See, e.g., United States v. Jeffers, 342 U.S. 48, 49-50, 54 , 72 S.Ct. 93, 94, 96 , 96 L.Ed. 59 (1951). Dual ownership remains significant under the expectation of privacy standard. See Salvucci, 448 U.S. at 90 -91 n. 5, 100 S.Ct. at 2552 n. 5; Rakas, 439 U.S. at 136 , 99 S.Ct. at 426 .

(3) The fact that the boat, when searched, was returning from a delivery of marijuana to Quinn and was, thus, pursuing the purpose of Quinn’s joint venture. See United States v. Pollock, 726 F.2d 1456, 1465 (9th Cir.1984); United States v. Johns, 707 F.2d 1093, 1100 (9th Cir.1983), cert. granted, — U.S.-, 104 S.Ct. 3532 , 82 L.Ed.2d 838 (1984); United States v. Perez, 689 F.2d 1336, 1338 (9th Cir.1982) (per curiam). Where a joint venture is being pursued, the mere fact of a joint venturer’s absence from the place searched is insufficient to establish abandonment or relinquishment of the property seized. See Johns, 707 F.2d at 1099-1100 . Compare United States v. Mendia, 731 F.2d 1412, 1413 (9th Cir.1984); United States v. One 1977 Mercedes Benz, 708 F.2d 444, 449 (9th Cir.1983), cert. denied, — U.S.-, 104 S.Ct. 981 , 79 L.Ed.2d 217 (1984) (no interest in the continuing transport of contraband deriving from a joint venture).

(4) The fact that to find the marijuana it was necessary to pump out the forward hold of the boat, indicating that reasonable precautions had been taken to preserve privacy. Compare Mercedes, 708 F.2d at 449 (contraband was “arguably in plain view”).

Reversed and remanded for consideration of the merits of Quinn’s motion to suppress.
