Can you summon multiple unseen crews?

[Senko]

I was looking at sea vessels and it got me wondering unseen crew summons 1 crew/level and I'm wondering could you cast it mulitple times to have the 50-200 crew for larger vessels?

Description
An unseen crew member is an invisible, shapeless force that performs the duties of one crew member. It can tie off ropes, hoist sails, swab decks, and other such duties. An unseen crew member possesses no other skills. It cannot fight, speak, or even defend itself.

An unseen crew member has a Strength score of 10 and a Profession (sailor) score equal to half your character level plus your Intelligence modifier (for witches and wizards) or your Charisma modifier (for bards, sorcerers, and summoners). It cannot fly, but it can climb, swim, or walk with a base speed of 20 feet.

An unseen crew member cannot be killed, but it dissipates if it takes more than 1 point of damage per caster level you possess from area attacks (it gets no saves against attacks). If you attempt to send an unseen crew member beyond the spell’s range (measured from your current position), the crew member ceases to exist.

Yes. You create 1 unseen crew member per level. So if you need 150 crew members, and you're level 10, you can cast it 15 times to get 150 crew members.

Get a MM Rod of Extend Spell if you're planning on making a habit of this.

Thanks I've seen a couple of spells work on a "new casting resets duration" and wanted to confirm there wasn't an erata or similar for this so it'd work like that.

Spells only have that limitation when it’s listed in the spell text.

What’s really funny is that the spell has a material component but doesn’t list the material. Probably meant to be the same as unseen servant.

Like Melkiador said, that would be listed in the spell description if that was the case. If your GM rules otherwise, then it's a house rule.
