Former Hampshire professional Ravenscroft has not played in an ICC tournament for Guernsey in three years and this will be his first appearance under the captaincy of Jamie Nussbaumer.
However, Ravenscroft's experience will be vital in a 14-man squad which includes six players aged 19 or under.
The tournament starts on Saturday 9 May and lasts for five days.
