ODD JOBS

Doing a few odd jobs.

Saterday I think it was. Håkan and me was out sailing. The wind was Beufort 3 maybee. The picture shows my AIS speed on Marine Traffic, 2.6 average 4.3 maximum. If Exlex can average 2.5 knots I be happy so this is a happy start
Here I am making a mosquito net. A light chain is sewn on to hold it down inside the hatch coaming.
Exlex sculling oar has excellent bollard power but when the boat is making speed through the water it kind of floats up. Only rapid mowement helps. I am a spokesman for slow sculling strokes so I am making a new oar. The picture shows me using my table saw. I have clamped on the shaft to a rolling table to keep the same angle when sawing the slot. The laminating blade is standing on the table. This is slow work because first I have to wait for the glue to set on the blade then next day I glue the blade to the shaft, the next day I reinforce one side of the oar with carbon next day the other side, next day I glue a stainless steel tube around the shaft to prevent wear, but I am getting there.
A friend told me that someone has said that I should have done the roll-over test with masts. It was not practical because the water was to shallow. However I do not worry becouse as you can see the mast floats, they have lots of positive boyancy. With masts standing Exlex will have even more rigthning power. True the sails will damp the motion but that only makes the person inside more comfortable. The rightning moment even without masts is very strong when the boat is upside down all the way to 180° of heel. And yes my visitors is my friends Lena and Beppe 

Soon the sculling oar is done and more sails will be done.

The plan is to trail Exlex to the West Coast for more sailing. The future looks bright.

EXLEX SAILING IN VERY LIGHT WIND

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.

MORE TESTS

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.

SHE FLOATS

Toaday Exlex was launched. A rollover test also was made. She has positive stability to 180 degrees.

Unfortunately the ventilation system did leek. Seawater entered the sleeping cabin. It can be fixed but will be difficult.

Soon sail test will be made.

Below are two videos.

MY WAY OF ATTACHING SAIL TO BOOM AND YARD

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.

A video belov illustrates.

WEIGHTS OLD AND NEW COMPARED

The weight of new Exlex is 660 kilos.

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.

WEIGHT

Today Exlex weight is 660 kilo. I can live with that I had wished for 10% less.  It is much better than her predecessor.

The original plan was for voyages not more than 60 days, as building has progressed my ambitions have grown. I think I can live on 1.5 kilos a day 1 kilo water and 0,5 kilo food. For 166 days I need 250 kilos.

250 plus boat is 910 plus myself 70 kilos gives a total weight of about one metric ton that should give me a range of 8000 miles at 2 knots speed or from Argentina to Australia. Hopefully this version of Exlex is faster than her predecessor. Anyway this is just wishfull dreams.

Below some media.

314 kilos foreward 316 kilos back 3 masts 7.5 kilo Rudder and tillers 19 kilos
Sumbeam systems solarpanels glued the wires enter the cabin below the panels.
Exlex now has her name written on her. The sculling oar in a handy position.

Exlex is now painted

Exlex is now painted. I have not done a good job of it but I think its OK with father Neptune that I spend time on more important things than finish. I do start to see the end of the building process. What still is failing is solar panels and to connect some electrical wires to test the AIS navigation lights and other things.

Hopefully I can get her into the water in the end of this summer for a test sail. The test sail will give me an indicatien of her speed thuse I can calculate her range and possible destinations.

Now and then like to day I put out a video on my youtube channel so subscribe. Hopefully the videos will be better.

Also please support research and development of these small seaworthy low energy boats.

Two pictures below.
