How much do you allow for good intentions? Do you count off for bad luck? Generosity on both matters is required if the merits of "Coaster" are to be appreciated. "Coaster" is a full-length documentary film about the painstaking building of a coasting schooner, the John F. Leavitt, which unfortunately sank on its maiden voyage. It is not about the sinking, but about the project as planned, which is romantically endowed with the beauty of a heroic dream. The final outcome is obviously heart- breaking for the filmmaker, Jon Craig Cloutier, as well as for Ned Ackerman, the man whose dream this ship was, and for all of those on both crews. Years of work and money went into all this, and because of the old-fashioned ship-building skills involved, the making of what would have been a standard cargo ship years ago, is viewed as a poetic endeavor. It needed only to fulfill its aim of shipping cargo along the East Coast to serve as some sort of triumph of craftsmanship over technology, as ratified by the great ocean. But there was this little problem. And there is the question of what, if anything, was salvageable. The ship was clearly not. Some of the film, documenting the no-longer-used skills of the building, was. This, too, was made with care and skill. But a feature film for general distribution cannot afford to ignore something so dramatically relevant as the fate of its chief character. It does not attempt to tell its audience, whose emotions have been engaged in the venture, why this ship sank. Presumably, it was just bad luck, but the film has avoided the issue for a lame ending claiming that the dream was salvaged, that it lives on. Does it? Will another such ship be built? Is a doomed dream the same thing as a dream come true? Can the filmmakers honestly say that their dream wasn't spoiled? COASTER -- At the Inner Circle.
