Submersible Question

Hello. I'm sure this information is available somewhere but going through the big submersible thread made my eyes cross. I have my submersibles setup for gil farming. WSUC++ They are all rank 133 right now. But I'm thinking to setup one of them for exploration and going for some of the items that only come from the voyages. What would be the best build for that? If it requires multiple builds (one for leveling then one for exploring) I'm fine with that.

Thanks in advance.

Rank 145:

Hull, modified coelacanth, Stern, modified unkiu, Bow, modified syldra, Bridge, modified syldra.

The one build to rule them all.
