Experts are where your skill comes from, and vets are 4 times as good as an expert.

Having 400 experts is not as good as having 300 experts and 100 vets. So the solution is
to get to 100 vets as early as you can manage and then fill up on experts. (You can have
more vets than that, but sailor ability can only rise so high and you have to think of how
many experts you're killing to make those vets...)

ohh...you mean that i have to convert my experts on my eng until 100 + and after i get
that rate of vet ill just keep on playing until my experts is fully high?.....

Um is it better than what?

to try and help

1 vet = 4 experts

so 100 vets is the same as having 400 experts on your sailor.

But you will gain experts as you play, you only get vets from buying or converting them.
So get as many vets as you can up to around 100 then let your experts grow and you will
have good enough sailors.

Vet as much as possible, and always try keep full expert.

Those highly vet + full expert Engineer contribute to
-Engine ability cap till cap
-longer overheat time
-better repair rate
-higher SD cap at 900
