During the beta, the Tatars had access to Shipwright.
Sometimes it is not cost-effective to research Shipwright, when the player plans to create only few ships. If in-game food costs the same as wood, there should be 4,000 wood spent to get 1,000 (food) for free because of the discount. This means that Shipwright will pay for itself after creating 25 Cannon Galleons or 72 Demolition Ships. Also, the technology does not affect gold cost. As a result, the main technology use is for faster ship creation speed.
Men who built and designed ships were called shipwrights. Their value to sea coast communities increased as the demand for sea trade and war ships increased. Expert shipwrights built sturdier ships at a lower cost.
