Alan is quite right, I can help you with this - I thought I sent you a pm about it last week actually.
But anyway, I was one of a team of five who took an 8.5m Delta from the Isle of Man to Trondheim in June/July 2000.
The purpose of this trip was to replicate in reverse (if that's possible) the Odin's Raven expedition of 1989, when four of our crew had been part of the Manx/Norwegan crew that rowed a replica viking longship from Trondheim to Peel in the Isle of Man.
Contrary to jwalker's comment, because we planned to make all the stops that Odin's Raven made, the trip was obviously going to take much longer than it would have done had we scheduled the route at rib speed. So to make best use of our available time we planned to freight the boat back and fly home ourselves. Our skipper, Nigel Wood, actually flew his family out to Trondheim for a few days boating in the Fjord after we deckhands had flown home!
Although I wasn't involved in buying the boat, it was passed off as being set up for a trip to Iceland - clearly not the case as it turned out! Although the Delta is a big lump of a boat and served us very well, the fuel tank was tiny, and as a result we had to carry fuel on deck and even refuel at sea once! A fair bit of work had to be done to it to make it fit for the voyage.
We made a number of stopovers on the west coast of Scotland followed by Kirkwall, Fair Isle, Lerwick and then overnight across the North Sea to Bergen. Then Moloy, Alesund and Trondheim. The weather was pretty crappy all the way which saw us either in the bad weather or trying to keep ahead of it. We only had one really nice day which we spent drifting and drinking between Iona and Staffa.
We had good coverage in either a late 200 or an early 2001 edition of Rib International.
The trip is quite straightforward as long as you have a suitable boat, the right weather, and of course you are personally capable of it.
I'm very happy to give you what help I can, just let me know.
