We are very proud to present our newest expedition partner Webasto!
With the Arctic climate promising to keep everything, including us, nice and cool the issue of heating has always been a central safety and comfort issue throughout our planning. Thanks to Webasto a hightech airborne solution has been found in their Webasto Evo 3900 air heater witch delivers 4kW of heat. The heater will be installed with three outlets giving us an even heat throughout the boat allowing us to keep warm and dry our foul weather gear in the wet lockers and head.
The Evo 3900 meets all our stringent demands of being a powerful, durable heater with great electrical and fuel efficiency. The heater can be run while heeling and can cope with the turbulence caused by the sails. As mentioned before heating the boat is both a safety and comfort concern and we now have pecace of mind having Webasto as part of our team. If you would like to have more information regarding their wide array of products visit them here at http://www.webasto-marine.com/
Pictures and posts about the installation to follow in the near future.

My good friend Olof came to help me out with the insulation this weekend. He will aslo be joining us for the Malmö to Greenland voyage if gets the time off from his work.
Today we painted the copper tape for the radio with floor paint to protect it from corrosion before insulating the aft berth. Now all the easy insulation work is done. To be able to continue I need to take apart the galley and aft bulkheads and insulate the ceiling in the aft berth where there is no sandwich laminate. Before the insulation there was a delta (difference of temperature) of 15 degrees C with a 2 kW construction heater. Now with the job partly done the delta is 26 degrees C and I´m thinking it might be enough, mostly because the difficulty of the remaining jobs.

No rest – the scale of the project is beginning to show, and I wish there was 48 hours in each day. Wish Nick was here to help me out.
Right after the boat fair I begun the job of insulating the V berth, it turned out to be just as easy as I thought it would be, the whole thing took about 6 hours. My original plan to glue the foam with water based contact adhesive turned out to be unnecessary. Since the foam is a few millimeters to thick the battens pressed the foam against the hull. Even if I would manage to get a perfect joint there would still be condensation between the hull and foam. My plan is to insulate the white bulkhead towards the anchor-locker from the outside so I won’t have to destroy to much of the interior. I could cut a foam board to fit or if I feel lazy I will just spray it with construction foam.

I visited the boat fair in Göteborg today. I made contact with several interesting distributors and collected a lot of information about water heaters and the possibility of connecting them to the engine’s cooling system to be able to preheat the engine and to make use of the excess heat from the engine.
Everybody I have been speaking to has advised me to get a new engine due to the age and model. More doubt and thought about how to finance a new engine!
On the way to Göteborg i also stopped in Bua to pick up 30 square meters of foam for the insulation.

The next project is the insulation. I have very poor knowledge on the subject, but after some research on sailing forums and many conversations with my brother who is a refrigeration engineer, I came to this conclusion; 20 mm foam, the same type used for camping mattresses. It can be purchased from NMC cellfoam in Kinnahult.
Inside the hull the insulation will be easy to install because there are teak ribs which are screwed onto the fiberglassed reinforcement bars. Just glue the insulation on and reinstall the ribbs. Since the deck is a laminate with 25mm spacer material sandwiched I won’t have to insulate the roof. But insulating the rest of the boat without destroying the interior is going to be a challenge.
I have no idea how I will insulate around the windows. There is no time to tear down the PVC mat and than redress the insulation with new mat. Do I even need to insulate here? Of course, more insulation will reduce the diesel cunsumption, but how do I figure out the ratio of the work it takes to actual benefits the extra insulation provides?
