Bristol is nearer to Dublin. There are no standard ferries operating between the two. You would need to go to the town of Holyhead in Wales to get a direct ferry to Dublin, or go to Fishguard and get a ferry to Ireland and then drive to Dublin.

This will be a decision of air traffic controllers. Many flights coming from London and other parts of Europe that are heading to North America, fly over the south of England and Wales, over the south of Ireland and on across the Atlantic. That can mean that it can be a busy route, so the alternative for London to Dublin flights is to fly north towards Manchester and then across to Dublin.
Fishguard is in Wales, not Ireland. You'll need to take a ferry to get from Fishguard to Dublin or Vice Versa. There are daily ferries, they take a few hours.
