Yes indeed, I dare say that the lawyers are busy. The vessel was constructed by Incat in Tasmania. She was purchased by MGC Chartering of Ireland. LD Lines have chartered her from MGC Chartering.
She will now lay up until Easter. Having an expensive vessel out of service for all this time is big money and the terms of the charter party will dictate whether LD have a claim against MGC, and the latter may also have an issue with Incat. As an aside, the amount of miles she has so far travelled in service must be far less than the 11,726 nautical mile delivery voyage from Australia.
The Incat website has a video showing a trial loading: "112m WPC Truck Turning Trial - a total of 28 trucks of three types drove on and off Hull 66. Times recorded confirm that the ship can be fully loaded in accordance with the ship's specification."

Significantly perhaps, the video only shows a single truck being loaded on an otherwise empty cardeck. This operation in itself appears somewhat tortuous. One would imagine that it would be a lot more difficult towards the end of loading when the cardeck is already almost full.
Rather optimistically, the website also states: "The reduction in port turnaround times through the development of Incat's unique vehicle deck arrangement has received widespread endorsement from an industry where every minute and every dollar counts. While early vehicle craft were equipped with bow doors, contemporary commercial vessels load and discharge over the full width stern, enabling a capacity load to discharge within minutes. By comparison, single lane discharge through the bow of the craft is a relatively slow and tedious process."
In point of fact, the lack of bow doors appears to be the primary factor in the slow rate of load and discharge experienced. Her replacement, the Norman Spirit, is a drive-through ferry which will be able to handle a much larger quantity of trucks and cars without any of the palaver involved on the Norman Arrow.
It is easy to be wise after the event but I do think that all this was eminently forseeable, as were the other obvious drawbacks involved with any fast craft.
