John
there is a Hartlepool lad (Terry) who does a lot of boats, he has a hi-ab haulage company. This also saves on craneage for loading and offloading.
He brought a Hartlepool charter, offshore 105, up from the south west so size and weight isn't a problem, as the offshore is 32 foot and about 8-9 ton.
Have you thought abought sailing it up, I recently took a Mitchel up to Blyth from Hartlepool, nice steady ride in a couple of hours.
Let me know if you need Terry's number
hope it helps
Paul
