One more darling gets killed in this video, the mowing ballast.
Doing some volyme calculations on the bilge keels I realised that there can be a lot of low weight in them.
That will increase stabilite a lot.
I also realised that with bilge keels the mowing ballast was now less important.
To keep things simple I am eliminating the mowing ballast.
These keels might be called twin keels or bilge keels.
I think in my case bilge keels is more proper as thier function is to provide stability and enable Exlex to take the ground more safely.
They are only 0.18 meter deep but 1.5 meter long so very low aspect ratio.
Twin keels I think are more for also provide better efficient windward sailing.
This boat have the combination of a bow centerboard and bilge keels.
The idea is that the bow centerboard will provide the efficient lateral area, the bilge keels stability and ability to take the ground.

Sven Yrvind
Hi My name is Sven Yrvind. I design, build and cruise small boats. 1962 I left Sweden in 15 feet converted Blekingseka. I soon found out that there was room for improvement. To understand the basic I began to study mathematics and engenering. 1968 I sailed to England via many contries in a converted 13 feet rowing boat. People told me I be more happy on a bigger boat. November that year I found a wreck an old steam launch build 1885 I converted her to a staysail schooner and sailed her to Rio de Janeiro. That voyage advised me that a bigger boat do not bring happiness, happiness is an inside thing. I designed a 6 meter doubble ender built her in my mother basement. Tried to sail around Cape Horn with her but was capsized and pitchpoled. Later I built an 5.9 meter boat in her I rounded Cape Horn in the southern winter June 1980. I have continued to design, build, and cruise small boats often in high latitudes. Please support me on my donation button on my site yrvind.com
