Great that you have been able to find this. I am a bit confused by the two scales given 1:10 and 1:20 but as you indicate things would be a whole lot better if I was a fluent Dutch speaker. 35kgs in the keel doesn't seem enough but its on the BOTTOM of the keel with leverage not at the top.
All we need now is the rest of the plans including a table of offsets for the frames and a person could build one !!!! LOL
Alden,
There is enough dimensions given on the drawing so you could develop your own table of offsets of the sections (at least close to). From what I can gather the newer Larken Klasse are being built with the same scantlings as they were being built before WWII. You would have to dig through the last page or two of the J.H Kuipers article to get an idea of planking thickness. I have no idea what the overall weight of the Larken Klasse is.
Rod,
You are quite correct, with a bit of 'tweeking' this plan could well be used to produce a yacht.
I have the plans to a very nice catboat that was in an old 'Rudder' magazine. The full building plans were published including the table of offsets. The given scale was 1/2" to the foot. I used a given measurement on the plans as a guide and used a photocopier to enlarge part of the plan to the correct enlargement percent (300). I then took the magazine to a copy shop and had the plans enlarged. I now have a complete set of unable construction plans to the correct scale. - Something of this order could be done with the plan on your post.
What's apparent is that because of the keel a bigger sailplan can be used making I suspect great performance overall and enhanced performance in lighter air.
Max I think asks an interesting question on one of his comments - put a keel on a Laser?
I think it's a perfectly good question! - a keel on an OK dinghy? a Finn? - even a drop keel with after sailing drain away water ballast would make sailing some of my favourite dinghies a lot easier for an old bugger like me with dodgy knees!!
That's "usable" construction plans, Not "unable" !
Alden,
The keel/dinghy hybrid singlehander might be worth a post down the road. There have been some attempts, none hugely successful. I can't imagine someone out there hasn't put a keel bulb on a Laser but if it has happened it hasn't made it into the InterWeb search tenatcles.
