[gurps] Delay spells question

[midnightwind at comcast.net]

Soliciting opinions on a ruling regarding Delay spell: 


A mage wants to cast Explosive Fireball with the Delay spell linked to it on a small amount of clay.  The conditions of the Delay spell are that a dolphin (either via Create Animal or Control Mammals) swims the clay to an oncoming ship some distance away, leaps, attaches it to the (wooden) hull just above the waterline and swims away.  The explosive fireball detonates five seconds after attachment. 


The Link spell denotes an area of detection, implying that the spell cannot be moved.  The Delay spell only talks about a certain duration and set of conditions being met-- but technically, this enhances the effective range of the Explosive Fireball to as far as a fast fish can swim (or bird can fly if one projects this to other settings) in the time duration of the Delay spell.
