Leah owns a motorboat specially equipped for fishing. In addition to the outboard engine, it has special seats, trolling rigs, and an electronic fish-finder. She offers to sell the boat with the motor to Tranh for $20,000.00. They also agree that the special seats, trolling rigs, and electronic fish-finder will be included for an additional $2,000.00. The written agreement refers to the sale of a boat and motor with "fishing equipment" for $22,000.00, with a deposit of $2,000.00. Before the sale is completed, Leah decides she would like to keep the fish-finder. When Tranh objects, Leah tells him they agreed to sell only what was specifically in the written agreement, and that the fish-finder is not included.

Assess Tranh's chances of obtaining the fish-finder, and discuss his alternative remedies.
