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.
I have been out in Exlex more times. With crews. Problem is my eyes are now not the best or do they make the print in the charts smaller nowadays.Its a lot of rocks here and I have a daggerboard not a pivoting centerboard. I do not like to damage its so I am prudent.
Below two videos from today 19 August 2019.
Its friends that have helped me to put up this on youtube. Its kind of to modern with music and stuff to my mind it is confusing but it has to do bucause the purpose is to show Exlex sailing so it has to do.
I will stay here in Hunnebo a bit longer. The natives are kind.
Yesterday Exlex was out sailing in very light winds. Frinds with a small unmanned remote controlled helicopter did a video.
Today one year ago I started making a half modell then a modell 1:5 scale and finally a male mould. So the building time for this new Exlex is less than a year. And, she works just fine. Its a good boat. Its enough to be in her to make me happy.
Today I have been sailing Exlex two times light winds on boath occasions.
She sails very well and comes about easily. She is very stedy. I am happy with her. There is however room for improvements here and there. Something for the coming winter.
There is some videos made of her sailing. A friend have promised to put them on my webbsite. I am an 80 year old dyslexic and have very pour knowledge about computers and such things. I leave it to freinds when they have time.
Below is a photo showing Exlex exelent stability click once or twice to enlarge.
This is a cheap and weight saving method. I use bits of Tufnol with holes drilled in them in it attached with carbon fiber rowing and NM-epoxy to the spars. In the holes I have Dymema strings and loopes. With the strings and loops I can knot the sail to the spars with kind of Truckers Hitch knots. The booms have three strings, the yards one string. The three strings is for reefing.
I plan to use 0.5 kilo food and 1 kilo water, maybee 0.6 kilo food and 0.9 water daily. If test sails show that Exlex makes decent speed I hope to sail to Australia via Argentina in three passages. I calculate with at least 2 knots speed, hopefully faster.
First Dingle Ireland to Porto Santo Madeira 1200 miles 25 days. Provision 38 kilos. Weight of boat and provisions 700 kilos.
Secound Madeira to Mar del Plata Argentina 5500 miles 115 days. Provisions 172 kilos. Weight of boat and provisions 832 kilos.
Third Argentina to Australia 8000 miles 167 days. Provisions 250 kilos. Weight of boat and provisions 910 kilos.
Previus Exlex had a weight of 1168 kilos provisoned for New Zealand. I had to do a restart in Madeira. The upcoming voyage have more easy stages and the boat is much lighter, her center of gravity is much lower, her lines are sweater. She also have a toppmast and a topsail, her beam is increased from 1.04 cm to 1.22, she is much roomier.
My plans for Next Design are lenght 8.4 meter beam 1.4 meter 1.5 tons loaded. If I get old I will add an electric engine as a complement to the yuloh. She will have better autonomy.
