I'm thinking something large enough to pluck sailors from a sailing ship. I also remember a movie set on a Canadian lake I think. Ah yes Eye of the Beast, typical SciFi channel rubbish but good on the dragging people into the water.
So as long as it's got tentacles long enough to reach up to the poop deck that's fine. The arms don't need to be especially lengthy as I don't need the ship to be crushed. A standard Architeuthis female with say 6m tentacles and 3m arms would work. Gigantic squid with shorter arms but overall larger size is a possibility as well. It's pity the Vampire Squid is so small, with a name like that it should cause terror amongst seafarers.
So let's say STR 3D6+20, CON 3D6+20, SIZ 3D10+12, INT 8, POW 5, DEX 2D6
Tentacles 75% for D6 sucker and tooth damage, pass grabbed victim to Arms or beak
Arms 60% for grab, 2D6 per arm per turn crushing damage, pass grabbed victim to Beak.
Beak 60% for 2D6 damage
Av. Damage Bonus +1D12
Armour - Rubbery skin
Move 12m in water
Tentacles have Reach VL, Arms L
Hit Locations - Head 1, Body 2-3, Tentacles 4-7, Arms 8-10
HP Head 18, Body 20, 2 Tentacles 15 ea, 8 Arms 15 ea.
AP 4 all over.
