ENKEL BÅT ENKELT LIV
SIX BEAMS LONG
The lengths and sail area of sail boats have been taxed by governments and punished by racing rules to such an extent that these boats are inefficient.
Cargo boats naturally have to be burdensome and racing boats naturally have to be built to racing rules. Cruising boats do not necessarily have to have these restrictions, but human beings are sheeplike when they see a racing boat winning a race they think its fast even when its restricted by racing rules.
Only a few boat types, like the Cornish pilot gigs, about 10 meter (32 feet)long with a beam of 1.5 meters (4 feet 10 inches) and the whale boats about 9 meters long and 1.5 meters beam are uninfluenced by rules.
Both use oars and sails for propulsion, Using oars in a sail race is of course strictly forbidden.
The Cornish pilot gigs was used as shore-based lifeboats that went to vessels in distress. When the whale had harpooned it would often pull the boat in a “Nantucket sleighride” trying to escape, sometimes against a rising gale. In both cases seaworthy boats were needed.
Sail area are restricted by racing rules. This has led to the Bermudan rig. Its based on the airplane wing theory. The airplane has two wings they cancel each others healing moment. Sailboats are different they use deep ballast keels to get stability. Lead is heavy. Much sail area is therefore needed to propel them. The lead keel is little use downwind and cruisers sail mostly downwind. Lenght of mast is more important than sail area to the cruising man. This week my Next Design is six beam long 6.96 meter with a 1.16 beam. Hopefully my economy gets on an even keel when I get to Australia enabling me to build her.
Surprisingly food for 360 days took up less space than expected. This gives me the possibility to add more water. I have added four 12 liter jerry cans in the aft port hatch. Tomorrow I try to do the same on the port side. There is already about 47 liters but not so close packed.
More water at the aft end and low down will give the boat more stability and make her easier to self-steer down wind.
Besides that I will spend Easter antifouling the hull for a secound time.
Progress have been made on Next Design. She is now 7.8 meter long and 1.28 meter beam.
At 1.2 tons dispalacement and a waterline of 7.2 meters or 23.6 feet she will have an lenght displacement ratio of about 90 which is good for planing down wind in a good breeze.
She will also be small enough to yuloh with little effort even by an old man.
She has a strong flat bottom and a draft of 20 cm or 8 inches. She will be good for deep as well as shallow waters.

During my planned long sail some days will be gray with contrary winds. To prevent me from start to feel downhearted I will bring with me a model of Next Design.
The one I have shown pictures of scale 1/20 is to big, there is no place for it. Therefore I have made onother one scale 1/40 eight times as small by volyme.
To cheer me up I will look at my small model instantly I will realise that although it is gray abouve the clouds mother sun is shining as brightly as ever. My heart once again filled with sunshine I will fight the contrary wind and make progress.

While working on Exlex a prototype I am thinking of next design.
All the errors I encounter I tell myself I correct that for the next design. I also get bright ideas. One such is to have an two meter long aft cabin with a bunk for a short girl. It will also contain the lunch-room if you sitt atwarth-ships. To make that possible I have increased the beam of next design to 1.4 meter. This has enabled me to make the boat shorter. Next design is now 5.6 meters long or 18′ 4”.
The hull made of 5 cm thick Divinycell reduces the inside beam to 1.3 meter. I need about 1.2 meter sitting space so plenty of room. Headroom is 90 centimeters.
The picture below illustrates the idea.
