In reply to David Coley:
My partner and I visited Tasermiut Fjord last August 2015, not to do rock climbing but to trek through the Klosterdalen valley (if you are interested in a video of Klosterdalen including views of Ketil look at our video:
Some info that might help. We used a locally based Spanish company for the boat transfer. The company is called Tasermiut South Greenland and their website is
http://tasermiutgreenland.com/ We dealt with Radu, the manager in Narsaq but the the transfer was done by their local man in Nanortalik - Jose Terjo . Jose is also a rock climber and runs the company's hostel in Nanortalik. At the moment I think that Jose is back in Spain for the winter but you might be able to get contact details through the company via the tasermiutgreenland website. We paid about £500 for a drop off and collect for 2 persons from Klosterdalen.
Another useful contact is Niels in Nanortalik Tourism
http://nanortaliktourism.com/ He can also arrange boat transfers and book local accommodation in Nanortalik. Niels has a shop selling some outdoor gear and can supply fuel for stoves. There are two supermarkets in Nanortalik but we took mainly dried food on our treks which we brought from Europe. Niels does keep topos of some of the climbs in the Tasermiut area.
One final bit of advice, be prepared for the biting insects. There are the worst that we have experienced any where in the World. It forced us to wear headnets generally when below 600m elevation.
