I have ruddercracks through both of the two upper hinge cutouts.
It appers that there are hollow sections in the rudder at those two locations.
Is that a known defect or have I just been unlucky?
Kind regards, Jan.

PS. As the middle hinge is below the waterline I intend fill the inside with a twocomponent polyether foam before I seal the surface cracks.

Please visit the brand new facebookgroup called "Great Dane 28".

Hello, Ralf

here in the states, holding tanks are required. On the great lakes, it is forbidden to have the capability to pump overboard. as i still have my blue water registration, i'm able to have that capacity if it is sealed shut.

I have a two position Y valve, which either pumps overboard (forbidden) or into a plastic holding tank under the Vee berth. this is emptied via a deck fitting labeled "waste." I assumed, since all my matching deck fittings are in English and German, that they were original to the boat. the waste is vacuumed out at a pump-out station, free of charge in all the harbors I know of. don't forget the vent line to release foul gasses topsides!

this is a page from a US distributor. i have a rigid tank; i have crewed on boats with flexible tanks, where the solids are "massaged" and helped out of the tank during pumpout.

(apparently i can't post a link., plumbing, water/waste holding tanks and fittings)

hope this helps. the plumbing of the hoses is the hardest part, since our head compartments are so small.

Dear All,
very recently I bought a GD28 that I will sail mainly on a lake (Wannsse/Berlin/Germany).
Waste water obviously is not welcome in the lake therefore I am looking for a solution to nevertheless be able to use the toilet. The boat I have still has the original (or nearly original) toilet layout, flushing everything outboards. Does anybody have experience with fitting a tank somewhere? I imagine this being nicer than a chem-toilet? Thanks for anything! Ralf
PS: as soon as we figured out a new boat name and have the register number and so on I'll post our whereabouts…

First to narrow slightly the search, have a look in the design of the cockpit and compare it to the third photo on the picture page. First boats built around 67 were like that: There is a step by the companionway and the post for the main sheet is low and made of grp. These first boat don't have a plaque like the one built by sanderson later on.
Come back if you want more but itsvery unlikely you ll find a definitive proof without a plaque or original sail.

Re: Hull Number by OliviaOlivia, 18 Feb 2017 23:17

my bad. the sail number is GD80. as i'm having new sails made for her birthday, could someone post the logo if there are no copyright issues? i'd like to use it as a class emblem, especially if i can verify the hull number.

Re: Hull Number by shearwatershearwater, 07 Feb 2017 19:18

Hi Jan, Jim

i agree there is already a post about hull numbers. but i think Jim's question relates to mine, is does anyone have any pictures of their hull number inside the transom? Olivia? there's a reference to finding it "hand written", so far i haven't found it on Shearwater, who has a sail numbered 180, but USCG documentation build year 1967.

Hello Jim

Try look down the tread and then you find - Hull number and building year? and be wise.

Where should I look for the Hull No.? I want to look up the history of the boat.

Cracks in rudder and repair.

Rudder by Kim Haslund AndersenKim Haslund Andersen, 27 Jun 2015 18:37

yes. Shearwater's was shortened in the aft dimension, i believe. it wasn't glassed in place (any more?) i did find a little sludge this spring whilst investigating the source of the diesel film in the bilge, but happily no water!

Re: New Fuel Tank by shearwatershearwater, 15 Jun 2015 20:00

Are all having the tank in the same place as Nepenthe, in the port cockpit locker out towards the hull?

Re: New Fuel Tank by AkkeBAkkeB, 15 Jun 2015 19:53

I did replace the old winches with Harken 39.2 ST three years ago and I haven't watched back since. Initially, I bought the 42.2 but went back to the shop almost immediately, deeming the 42 as too powerful for the old lady. The diameter of the winch base is the same for both variants and fits in beautifully on the old pedestal. The only tricky part is that you have to redrill the holes for the mounting bolts in the pedestal. All the holes ended up more than one diameter from any old hole. Drilling in thick stainless steel just takes low speed, high pressure, a sharp drill, patience and copious amounts of cooling fluid. Never ever let any point get hotter than a couple of hundred degrees centigrade or you will have a local hard spot that no drill known to man can get through and as a byproduct of that, a hole a long way from where you intended. A4 steel is in itself not much harder than ordinary carbon steel but let it become martensite and it's more grinding than drilling. Anyone interested in the old winches? The pallet springs in the hub have to be replaced and the winch hub could be replated. Just the metal value might have paid for the new winches. Heavy beasts but no corrosion anywhere.

Re: New Fuel Tank by AkkeBAkkeB, 15 Jun 2015 19:40

I kept getting soft black balls and clumps in the diesel when I drained the separator under the tank. All the flushing I tried didn't work.The answer was to cut an access hole in the top of the tank though the fibreglass, and replace with a circular plastic removable fitting. The tank could then be accessed from the cockpit, cleaned and steam cleaned, and that plastic entry fitting screwed back.
There was loads of sludge in the tank, - diesel bug. The filters could easily have been overwhelmed and the injectors blocked.
I didn't fancy the job of replacing the tank as it's bonded in.

Hi there,

I have added an excerpt of the September 2004 issue of Træfpunkt. which is the magazine of a danish ocean cruising association.
The article is about Peter Mathiessen, who previously owned Stella (#193) and sailed her single handed from New Zealand to the Falklands in 1992.
Please find the article under the following link: []

The article is written in Danish, but maybe Ole will find some time in the future and translate it for the English speaking folks.

Cheers and a great sailing season 2015!

Wishing everyone a happy new sailing year 2015. 2014 was a wonderful year meeting a lot of 'new' Great Danes out there. And thanks to webmasters Christian and John for keeping the site floating and updated. Fair winds, Ole, Brise II

Much appreciated. And happy holidays with best wishes for smooth sailing in the new year.

I've utilised all those spaces mentioned. Also, screwed thin plywood sheets behind each set of drawers beneath the dinette table to stop goods fouling the drawer operation. Screw into the end grain of the drawer runners. If cans are stored there I put a mat of cheap closed-cell foam against the inside of the hull to stop abrasion - as a cushion. For behind the battery, I would like another separator - foam mat might do - to avoid stuff colliding & shorting the battery. The companionway hatch - 'garage' roof, on deck - is another area to stow stuff externally —- a liferaft? The previous owner built 'seats' / platforms : one suspended across the pulpit. Another platform above the tiller/transon. A tubular steel gantry above the transom would be advantageous for solar panels, radar, etc. As said, adding to the weight is a problem.
