The Hansa dinghy was introduced in 1947 by Henry Rasmussen, founder of the renowned boatyard Abeking & Rasmussen (A&R). During the post war years there there was an Allied ban on larger new boats. The Hansa is really a keel boat with a fixed keel and has a draught of 50 cm. The ballast keel is 150 kg and the beam is 1.65 meters, which gives good stability, but still has the character of a dinghy. The boat is 5.85 m long, and was designed to be a small, safe cruising boat for inland and coastal waters.
This model is made from an Aeronaut kit. It has three servos, rudder, mainsail and jib. This means the model needs to be sailed "properly", changing the jib as you tack and trimming each sail to ensure the boat sails well. Its quite enjoyable to sail.

The Hansa dinghy was introduced in 1947 by Henry Rasmussen and a kit is available from German manufacturers Aeronaut, the hull is 940mm long.
Have made some reasonable progress so far and would be interested in hearing from anyone else who has built one of these kits, especially concerning the ballast.
The kit contains a plastic keel, which I have replaced with one made from 3mm stainless steel, to add some weight low down. The hull shape allows for lead shot and resin to be added, as on the real boat. The kit also does suggest an added "clamp on" weight to the end of the keel, which I'm planning to do. I'll drill a small hole in the lower area of the keel and use a two piece weight that can be clamped around the keel, with a pin going through the hole, to ensure the weight can not drop off. This is most likely to be made from brass.
Its the relative weight of the keel and lead shot that needs to be considered. Current thinking, is to add the weight to the keel, do a float test, with batteries and RC equipment etc on board, and then add lead shot to bring the boat down to its water line and correct trim.
I have found a couple of "build blogs" on German sites, but they seem to follow the instructions and just add lead shot in the bottom of the hull.
Any other suggestions or experiences? - thanks

Roy is right about using model railway parts. The handrail knobs are from a model engineering supplier and are intended for a 5 inch gauge loco, the actual handrail is 2mm dia. stainless steel, which just about fits the aprox. 1:10 scale that I'm working to.
As for painting, there is an initial two coats of thinned varnish and then a spray coat of a "filler primer" from Halfords. A fine modelling filler/putty is used to fill small imperfections, before rubbing down with some wet n dry. This process was repeated on two more occasions. The top coats will be completed using a spray paint from B&Q, aimed at furniture restoration. There are a selection of colours and the white is available in gloss, satin and matt finishes. The other option is car spray but tends to be glossy finish.
The red oxide, below the waterline, is a red primer from Halfords.

Have used spray paints for the hull. However, varnish does come from a tin but tend decant some into a jam jar, which means that opening the tin is kept to a minimum, especially if it is being used on a daily basis. The varnish in the jam jar is thinned 50/50 with white sprit.

Before going any further with the deck and rigging, felt that the hull should be "faired" and given an initial coat of paint. In fact it ended up with three coats of primer (yellow), with some fine filler used in places, rubbing down between coats. The final overall colour will be white, with a red oxide under the water line. A initial "dusting" of white confirmed there is no conflict between the two paints.

The roof is finished - using stainless steel for the handrail. Have also started to shape the lee boards. There is a need to think about other details, shroud fixing etc. There are a number of additional "wooden" parts that can be seen on photos of "real boats" which need to be added.
The underside of the hull needs priming and sanded smooth - think that will be the next task.

Thanks for the interest. Iโve not given up on adding a control to the Lee boards but at the moment itโs not on the โmust doโ list. Iโve struggled to find examples of other Dutch barge models, so itโs good to hear someone else has built one.
Iโll look at painting and finishing the cabin roof, then the next job will be the Lee boards.

The cabin now has a roof. This lifts off and then its possible to lift out the door and cockpit, which should provide good access to the inside of the hull.
The handrail along the edge of the roof needs to be added but I'll need some 2mm dia brass rod and will then add a further 4 supports each side.

A bought a pack of three capacitors, so will have the option, currently working on cockpit floor, door and finishing rudder.

Lovely model, sorry to see the damage. Interesting to learn more about how you built the hull. Am currently building a similar boat and the shape of the hull has proved a โchallengeโ to build.

A great looking model and pleasing to see a traditional sailing boat being built. Be interesting to see how well it sails and how youโve set the sail controls up.

The next step is to get the rudder and sail servos in and working, along with the motor control. That will use all the controls up on the Rx/Rc. Not using the motor control would make room for a servo/winch for the Lee boards. Decisions ?
Unfortunately I donโt subscribe to Facebook etc but thanks for the suggestion

Thanks Alessandro. Slightly to my surprise - I've struggled to find other models of Dutch barges - a few YouTube clips and that's it. There is more information about the building of model Thames Barges, which are similar in design to the Dutch version. These models seem to use a rudder extension and additional keel, I have designed/built the hull to incorporate a bolt on keel, just in case. It would be nice to avoid both of these and allow the use of the lee boards as on the full size boat.
It could be possible to use a sail winch mounted sides ways, so the lee boards could be raised and lifted, on a push/pull arrangement - but the boards would need to be weighted to ensure they dropped as the line from the winch was eased. The other option would just have them adjustable and made so they could be fixed in a down position.
All ideas to be considered.

Here's a couple of photos with the outer gunwales fitted and topsides trimmed, which shows the true shape of the hull.

Making mistakes - the greatest learning tool?
Colour? White initially, then perhaps red oxide or black under the water line. Think the rubbing strake will black, but thatโs all along way off. A few coats of white and lots of rubbing down will be needed first.
Next task, the rudder and operation via a servo.

I assume a second layer of planking may smooth things out but it seems reasonable at the moment and with some sanding and filler it should be ok. To be honest, I found the planking a little frustrating and not my greatest pleasure - so one layer will have to do !
Thanks for the video Ross - interesting but the challenge on a Dutch barge (or similar) is the bow, where the planks have to bend round 90 degrees, as the bow has the cross-section of a football, rather than a fine cutting edge, as found on a classic J class yacht.

Using a motor? - Certainly useful to beat a falling tide when coming into a drying harbour.

Originally there had be no intention to include a motorised prop, the plan being for just a propeller on a false shaft for pure aesthetic reasons. It is a sailing boat and Iโll admit to having no interest in powered craft.
However, as we should always be interested in learning new things, the decision was made to add the auxiliary power source. The actual prop size is currently 40mm, which just fits. I look some advice and the motor size was recommended, as was the specification for the speed controller. The motor/prop will only need to move the boat slowly when there is no wind, but that is along way off yet and we need to remember it is a sailing boat.
You can still hire sailing cruisers on the Norfolk Broads that do not have a motor. Such joy and thus skill needed.

This photo shows how the servos are fitted. The long armed servo controls the jib and with 2:1 ratio, there is just enough movement, so the jib can move from one side to another.
The servo controlling the mainsail is top left and uses a 3:1 ratio on the sheet and this creates enough travel to allow the mainsail to move out while sailing downwind.
The third servo controls the rudder. I use a FlySky FS-i6 transmitter.

Hi Alessandro - I tried the paste/return, but no change. There must be away of making the text/web address into a direct link. It does seem to work if you cut and paste, not ideal I appreciate.

Sorry the link doesnโt work, could someone please explain how to create a direct link from a post as I couldnโt work this out? I notice some contributors manage to embed a video into their post.
