STOWAGE HATCH CLEATS

The stowage hatch cleats are now ready as seen in the picture below.

The bottom right one is the first full scale mock-up. It has two different horns for testing. A piece of cupper pipe is used as a rivet. The final product have two rivets. Rivets are used becouse the can be ground down flat and smoth on each side of the hatch and of course no amount of vibration will unscrew them.

A COMPLICATED STRUCTURE

The full scale functional mock up of the aft structure have arrived.

It serveces several purposes such as holding the two rudders being a bath platform and bording ladder. It also holds the pipes spanning up the watercatching arrangements. to port there is the yuloh hardware and to starbord anchor handling gear.

The final product will be made of stainless steel the mock-up is ordinary construction steel. Mock-ups gives good guidence. Already I have listed seven changes to make.

Below are some pictures. Click once or twice to enlarge-

CLEAT LOCK

Production boats are built with the fiction that they will never capsize and few boats do, but that’s because they restrict themselves to conventional cruising as advocated by Jimmy Cornell and others; hence their stowage hatches do not have hardware that enables them to be locked.

Me, I like to be able to keep things in place even during capsizes. In previous boats I have been experimenting with different ways of locking the hatches. Here are a few considerations. Ideally the locking system shall not interfere with the inside space nor intrude on the outside it should be strong and simple and easy to open and close even in the dark on a rolling boat. It should be reparable at sea.

Here is the first mock up for YRVIND TEN. It consists of three cleats and a piece of Dynema string. It is incredible strong and nothing can go wrong with it. On my first small mock up it works well. Full-scale tests with the proper hardware will tell if it pass muster.

WORK HAS STARTED AGAIN

It is a long time since I did work on YRVIND TEN. I have had her exhibited in Göteborg and Stockholms boatshows. Also I have been making a trip to Holland to visit my old crew member Janneke. We talked about the days sailing Bris and being capsized and pitchpooled in the roaring forties near Cape Horn.

Very few small boats have been sailing in those waters. We boath agreed that a capsize and pitchpoole was completely harmless regarding personal injuries. As Janneke expressed it it all went in a flow.

Below a picture of Janneke in Bris

I have now starting with the stowage below the bed. The picture below shows me taking off the shape of the main dividing piece of plywood.

Next picture is me coating it with NM-650 epoxi it has very low viscosity high wetting and long open time, that is excellent for coating.
