I don't like hyperspecialized munchkins. I prefer slight generalization and slight specialization combined. Specialized for a task in another thing, and requires some depth and breadth. You are probably going to want to make a ship that can fly and/or submerge and move at the will of the operator. All Rego Herbam, some other arts perhaps. Then you might want fire suppression systems, resistance, magical supplies, replicators and transporters, a holodeck, etceteras. I am being silly to prove a point. You can go a long way on one concept. Have you taken a major magic focus in ships?
Talia has no desire to build a flying ship, unless it is a commission. Then there's the problem of enchanting the ship which requires a lot of Magic Theory. The focus in ships and boats only goes so far, you need to have other things to back it up. The spells to affect ships are interdisciplinary across many Arts, too, so she's not specialized except with ships and boats and the need for a ridiculously high magic theory.
What if you dodn't enchant the whole ship? Instead, enchant a device that makes the ship fly; a sail, a helm wheel, whatever. Ships that can sail the magic realm are cool too. Or be more simple and direct. Ships of the highest quality of great seaworthiness that sail faster and more nimbly than any other.
Actually, I am now very curious to see where you are going with this and further endorse a third cycle.
Part of my plan for the saga involved giving Mallorca a magic ship as a gift from Poseidon. If Talia could create such a ship instead by advancing an extra cycle, it would make it more personalized for the covenant, and additionally I'd work with you on getting Talia some assistance in its creation.
I'm not even sure she'd be able to do it with a third cycle, she might be close to starting the project at the end of the third cycle. I don't have a problem if Poseidon has given an enchanted ship to the covenant and Talia's there, with the ability to make more.
What are your difficulties? What effects do you intend to invest in that ship?
As marco noticed (and this is how I'd do it), you don't need, at least for your first projects, to enchant the whole ship. An individual item, with added size modifiers, can go a long way towards sparing your MT.
I can certainly see her as creating a "prototype" only able to do a few things, and, in a few years, do her real ship.
She may even "cheat", by using charged devices she uses only when needed, and replaces every few year. This would make the OoH marvel at how such a young designer could do such a ship, with only her knowing the truth.
For exemple, assuming she wants a lvl 40 effect, there's no way she can invest it even with a lab total of 40 (Say, MT + Int + Lab + Aura 15, Primary Art 15, secondary art 10). But once she's got the text, she can cram out an item with 8 charges per season, impressing and tricking everyone. To me, this sounds like the kind of things a tytalus could do.
Of course her first project wouldn't be to enchant an entire ship. But any item which can reproduce an effect can be stolen, and as I've said previously, it's much harder to enchant an entire ship. I want her to be close to being able to do so by the time she enters play.
That's fine, but the character's objective, the challenge is enchanting a ship. It's not a very Tytalus type of thing to lie to oneself.
Maybe its like prototyping...
Make something temporal to learn how to build the permanent version.
That's all they ever do! And they have been at it so long they believe themselves!
No. And I'd appreciate it if you not take that approach with Talia and me any further than this.
It is just a joke, the emoticons clearly indicate a facetious tone 
Not really, Mark. Your stance towards House Tytalus has been well discussed in public, despite what you might have said in private, and your public stance has been stated both in and out of character.
So, if you want to have Roberto take that approach, I'd appreciate it if you drop it out of character. Otherwise, it's not a joke, it is a defining characteristic of the player.
And the irony of that is Marko is the most Tytalus person IRL that I've ever known.
:mrgreen:
Quoted for Truth.
Hey, I am too skinny and weak and unskilled at combat to make a good Flambeau IRL.
:mrgreen:
I assume you have a Corpus deficiency as well, then, since all those things can be countered by some CrCo, MuCo and ReCo.
There is no such thing as magic.
There are girls. Close enough IMO 
Why would she be lying to herself? She'd know very well what she'd be doing, wouldn't she?
And it's a very tytalus thing to manage by "cheating" something she couldn't do otherwise. To surpass expectations. To think outside the box. It's also a very tytalus thing to try to fool the order into something, see if he can pull it of.
This also allows her to test effects without spending vis, see if that works as intended.
I don't want dozens of years of game time between the prototype and final product.
