Embodiments of the present invention provide an approach for goal-based user matching among social networking environments. More specifically, the invention relates to a watermelon plant having an allele which results in a multibranching compact watermelon plant with small fruit. The design accommodates any type of boat with a rail or gunwale. The system may also include features for enabling users to identify contacts of their respective contacts. The twist-tie provides a vapor-resistant seal, to minimize the loss of water and organic solvents from inside the sleeve through the sealed opening.
