A film showing the laminating process of Yrvind Ten

In this film is Yrvind and some of his friends working with epoxy laminating. Yrvind is using epoxy products from Nils Malmgren AB, NM Epoxi. For you who are interested, the last layer which is applied in this film, is a peel ply layer. When it will be removed later, the surface will give better adhesion to coming layers.

ON CLEANING WITH VINEGAR

I am thanking Manie B for the suggestion of cleaning with vinegar. However the vinegar is an acid and the epoxy hardener is an alkaline. The two react with each other. The harm will probably be minimal but when I discessed the issue with my epoxy chemist he did not like the idea. Insted I have dried the inside of the hull and am grinding the Divinycell down to un-contaminated core, just in case.

ASPECTS OF THE RIG AND WATERCOLLECTION

Matt Layden did teach me the advantages of the lugsail. I did grow up with the traditional Swedish spritsail.

Paradox and Enigma uses a standing lug. I plan to use a balanced lug. Like Matt I intend to reef by rolling the sail around the boom. Unlike Matt I will keep the boom inside a slotted pipe, much the same as in-mast furling. Its a complication but it has some advatages. It protects the sail from chafe against the mast. It is easy to attach a preventer to the pipe. When the sail is not in use it functions as a sailcover. And important I will use the slotted boom to collect rain water in. A hose from it will lead to plastic containers.

There are two masts and four positions for them. The masts are selfsupported, unstaid. Thanks to the lugsail the masts will be very simple, no tracks and no goosenecks, only one halyard. I plan to make the mast of carbon at Marström. I will make them strong. They will not be longer than an oar (how long is an oar?) The will be as easy as an oar to handle.

They will be close to the hatch, within 3 feet, 90 cm. To move an mast it has first to be mowed vertically out of its support. Being of short statue and getting older every day some windy days I may need a helping hand in the form of  a stick and some rope. Below follows some pictures click on them and click again to enlarge.

The slot where water is collected.

The sail rolled into the boom and secured to the deck. The mast is free to be moved.

The mast and the helping stick and the lifting rope.

With the help of a rope the mast is lifted out of the mast hole. Each mast hole has a rope that can be attatched to the lower end of the mast and controlled from the deck. Its function is to secure the mast and guide it when I mowe it. The picture shows the lower end of the mast at the moment when its out of the hole but before it is mowed. Before I disconnect the first rope I attach an other the rope from the mast hole to where it is going to be mowed. Two ropes are therefore at the moment connected to the mast. (look closely)

The mast is put on deck and its lower end is mowed to the new mast hole. Now it is very easy to raise it with one hand at the same time as I pull on the rope to drag it down the new hole. When in position the rope is cleated and the mast is secured in the new position. During the whole operation it has been under control.

The mast in the new position.

This is the theory, to be modified, all the details are not included. As Clausewitz said “few strategies survives the first contacts with the enemy.

A SETBACK

I had been away a week traveling all over Sweden giving lectures and talking to sponsors.  Things were going well. The last assignment was showing my previous boat to people at the opening of Pampas marina here in Västervik. At 4 pm I drove my boat back to Marström. Having a few hoers left of the day I went to my shop not to waste them.

Laminating the outside of the boat had been a success. We had done a good job on her and before that I had succeeded in shaping her well. I was proud of my small boat. She was so pure and clean, a real virgin.

I opened the workshop door. Before I could switch on the light I heard a sound that made my hair stand up, the sound of water, the sound of water in my workshop.

Water from pipes above where coming down in my boat. Not clean water, but dirty, rusty brown water. The boat had accumulated nearly a feet of the fool smelling evil stuff. I broke down and cried.

Had the inside been laminated it would not have been so difficult to clean it out. But now the Divinycell pores where filled with it. The water can be dried out but the rust and dirt never.

What will happen now? I don’t know. This happened a few hoers ago. Time will tell but one thing is sure. It is a set back and I will not sleep tonight.

To be continued…

Regards Yrvind.
