Clam is not so amazing anyway, especially early on when we have irrigated corn already. The reasoning behind the work boat would be to have it ready for city #2. If we put our 2nd city 1W of the fish it will be hooked up to our capital with fishing. If the work boat is ready that city will bring in 5, 1 and 5 instantly (+1 or 2 maintenance).
The 2nd city would also have cows and a grassland hill in the first ring which means no need to make a monument (possibility of loaning another hill from Bibracte). It will grow quickly and could support our expansion while Bibracte gets the GLH.
