As an update for this thread and any one in future needing a similar service:
Had the bike delivered by DMT couriers who are based in NI, but also do mainland stuff. Bike was collected and delivered to my door at 7AM next morning for £200 all in. Very pleased with the service - the van has a proper tail lift too which took away the headache of unloading. The fee for the boat alone wouldve cost me the same as this entire service so the price was unbeatable.
In summary, DMT come highly recommended from myself.
