The Danish island of Bornholm has been fought over for centuries by Denmark, Germany, and Sweden. The 227sq mi (588 sq km) island is the 8th largest in the Baltic Sea, lying 80nm east from the nearest Danish land, 45 miles from Germany and only 25 miles from Sweden. Prominent on the northwest coast of Bornholm are the ruins of Hammershus, the largest medieval fortress in Scandinavia, built in the 12th century as a base for the Danish Crusades.
The island is one of the sunniest places in Denmark and this, along with its diverse and beautiful scenery, attracts some 600,000 visitors per year. With a year-round population of roughly 40,000, the island is unusually well-served by ferries that seemed to be constantly arriving and departing during our three-night stay on the island.

Tuning Error
Position: 54°56.32’N, 12°47.94’E
Our main RADAR is a 25KW Furuno DRS25A. We find it amazingly easy to use compared to RADARs we have used in the past and it’s remarkably good at resolving small details like a fish boat working close to shore. Recently it’s started to produce “Tuning Error” errors which just last for a second and then are gone, but they are getting increasingly frequent. The RADAR has just under 10,000 hours transmitting and we know that any magnetron with more than 8,000 hours is living on borrowed time so we’ve been expecting a problem for the last couple of years. We have a very nice Furuno DRS6A backup RADAR with under 1,000 hours as backup, so we’re haven’t been in a rush to preemptively fix the expected magnetron problem on our main RADAR until we actually see it.
We contacted Furuno and they said explained that a magnetron will always have some fluctuation in output. The system will auto-tune for these changes in magnetron output and the operator will not see any impact from these slight changes. But, as the magnetron ages, its output will start to vary more and more and, eventually, the auto-tuning system will not be able to adjust for its variation and a “tuning error” messsage will be produced. Furuno went on to recommend turning off auto-tuning which is what is being done in this picture. This works well and the errors stop. Of course, the magnetron problem is real and it will still need to be replaced. Overall, we’re super impressed with the quality of Furuno support—over the years we’ve had few questions but, when we have them, the Furuno team is amazingly good at resolving them. They’re really a top notch organization. The downside of Furuno is the parts pricing is very high. For example, the video card in our NavNet 3D black box, was a $300 client computer part before discounting when it was first produced a decade ago, but currently from Furuno it’s $1200. Perhaps the high price is because the graphics card is now a museum piece :-). Similarily, the recommended replacement parts price not including installation for our DRS25A is half the price of replacing the unit. So our current leaning is to replace it entirely even though it’s an excellent RADAR with a high-hour magnetron. Overall, we wish the parts were less expensive but, on the whole, we continue to really like Furuno and will likely buy a new DRS25A RADAR this summer. The equipment quality is good, it’s very usable, and 9 years and 10,000 hours isn’t bad for a RADAR. |
Baltic 2 Windfarm
Position: 54°56.05’N, 13°1.94’E

Entering Ronne Havn
Position: 55°5.54’N, 14°40.41’E
Passing behind the outer breakwater into Ronne Havn on the island of Bornholm with the 396ft (121 m) ferry Povl Anker. The vessel is named after Paul Hansen Anker, who was active in the rebellion against Swedish control of Bornholm island in 1658. The owning company, BornholmerFaegen, operates three routes from Bornholm with two other ships and currently keeps the Povl Anker in reserve.
One of their other boats, the Villum Clausen, is in the Guinness book of world records for its top speed of 48 kts and the fastest distance in 24 hours achieved during the voyage from to Denmark from the Austal shipyard in Australia. This ship is named after an islander who shot the Swedish commander trying to escape arrest. Bornholmers seem to take their independence pretty seriously. :) |
Quay 23
Position: 55°5.76’N, 14°41.55’E
Water is not available at our berth, so we’re stopping off at Quay 23 to fill our tanks. Bornholm charges for water and power, so we’re also picking up the tally card that water and power are charged to, and paying our moorage fees.
|
Freke R
Position: 55°5.76’N, 14°41.55’E
The cargo vessel Freke R rounding the corner off our bow to enter the harbour. The ship doesn’t have thrusters and the skipper has to apply a fair bit of power to maneuver in the tight quarters.
|
Ronne Havn
Position: 55°5.97’N, 14°41.58’E
Moored for three nights in the commercial port at Ronne Havn. There’s almost no tidal range here, so we don’t have to leave the usual slack in the lines when on a fixed dock.

Position: 55°5.97’N, 14°41.58’E
From our berth at Ronne Have on Bornholm Island we had a great view to the island’s ferry traffic. This is the 518ft (158m) RoPax (combined freight and passenger) ferry Hammershus arriving at 5:45am after an daily overnight run from Koge, Denmark, just south of Copenhagen. The ferry was delivered in 2018 and has a service speed of 18 knots. It is named after Hammershus, a fortress ruin on Bornholm Island.
|
Express I
Position: 55°5.97’N, 14°41.58’E
As the Hammershus was arriving, the fast ferry Express I was loading beside us for a 6:30am departure for Ystad, Sweden. The (112m) fast ferry, built by Incat of Tasmania is one of the largest in the world and has a top speed of 40 knots, or 36 knots fully loaded with 1,200 passengers, 417 cars and up to six buses. We saw it’s sistership, Express 2, while travelling the east coast of Denmark last year.

The fast ferry Express I returning to Ronne Havn from Ystad, Sweden. The ferry makes four runs daily this time of year and eight in the summer. The island is incredibly well-served by ferries from Sweden, Denmark, Poland and Germany and over 600,000 visitors a year.
|
First Smell
Position: 55°5.97’N, 14°41.58’E
Spitfire getting his first smell of Bornholm Island.
|
Loudhailer
Position: 55°5.97’N, 14°41.58’E
We use a forward speaker as a combination of loadhailer and fog horn, both supported by one of our Icom M604 VHF radios. This forward speaker takes a lot of water when operating in heavy seas and, as a consequence, only lasts about two years. We have a backup speaker at the stern of the boat that can be operated as a load hailer and fog horn by the other Icom M604 VHF radio. The forward speaker failed on our last foggy outing so here James is replacing it.
|
Express I Arriving
Position: 55°5.97’N, 14°41.58’E
The fast ferry Express I returning to Ronne Havn from the second of its four runs today from Ystad, Sweden.

Locating Wires
Position: 55°5.97’N, 14°41.58’E
When the boat was new LED rope lights were installed behind the valence panels that surround the saloon. This LED rope light was always insufficiently bright and it’s now showing darkening from overheating. We’re replacing the LED lights with a new option that gives us control of color and brightness. Unfortunately, the old lights ran on 24VDC while these run on 12VDC.
Here James is attempting to locate the wire that feeds the rope lights in order to install a 24VDC->12VDC converter. He found the wire by measuring current to the old lights and switching the lights off on and on. When the correct wire is found, the current switches on and off with the appropriate light switch. |
Bike Island
Position: 55°11.72’N, 14°42.14’E

The Furuno DRS25A still seems to be available for sale (both the “classic” and a new variant):
* https://www.furuno.com/en/products/radar/DRS25A
* https://www.furuno.com/special/en/radar/drs6ax-class/
Would you go for a one-to-one replacement, or get get a solid-state system (either from Furuno or someone else):
* https://www.furuno.com/special/en/radar/drs4d-nxt/
Yes, thanks David. We already have a new DRS25A on order and we’ll pick it up when we are in Seattle in July. We decided to go with the same RADAR as was installed back in 2010 because it works without change on our Navnet 3D system and it’s a phenomenally good RADAR. We’re very happy with it.
