What man built large ships that Nephites sailed away on the west sea?
Inasmuch as any man belonging to the order shall be found a transgressor, or, in other words, shall break the covenant with which ye are bound, he shall be cursed in his life, and shall be trodden down by whom I will. Doctrine & Covenants 104:6
What man built large ships that Nephites sailed away on the west sea?
Hagoth
Hagoth ... built him an exceedingly large ship ... and launched it forth into the west sea. ...
Many of the Nephites who did enter therein and did sail forth ... This man built other ships.
And the first ship did also return, and many more people did enter into it; and they ... set out again. ...
One other ship also did sail forth; and whither she did go we know not. Alma 63:5
