I have a set of DaKine fixed harness lines where the protective tubing is cracking badly. My hoarding instinct wants to ask if there's any reasonable method to keep an otherwise good set of lines on the water instead of what my rational brain wants to do - chuck them in the bin. And, no, I don't have access to a sewing machine that could resew the lines back into the sleeves.

The lines are fine - it's just the tubing. But, no worries. I've been sufficiently shamed and will throw out the 17 sets in the closet that were awaiting some sort of salvation. 
Sewn in tubeing is a problem, but if the tube can be replaced, try semi trailer truck brake line air hose. Toughest tube I have found and just the right diameter and weight.
well that's weird, it's normally the rope inside my lines that goes well before the tubing. What sort of hook are you using? I've speculated that the roller style hook would be kinder on lines.
I have repaired my lines in the past, using a big needle and a pair of pliers, but that was replacing the rope inside the tubing, not the other way round.
And I agree air line hose is tough, but it's usually in a tight coil. Ok if it's just a half coil at the bottom of the lines, but doesn't work if you want it the whole line length.

Hook. I used to be 100% roller for years but when I started foiling, the lines came out way too easily as I wasn't - at that point - always able to apply consistent pressure. Still hook two years later out of habit and it's still easier on a foil as we release sail pressure much more often than with a regular board.
The lines came on a used carbon boom I bought a few years back so the tubing probably had some age and UV
Flying Objects fixed lines never break in the middle.
When they wear out it's eventually at the webbing, where the lines 'hinge' stiffly at the boom.
Best lines I've ever used, and I've tried a lot.
To be honest, Da Kine lines were always rubbish - and usually significantly shorter than other brands.
That said, the way any fixed length lines bed down is also a function of boom tube diameter.

I've only broken one side in over three years of use and that was after hitting a sand bank at speed at Burrum.

Probably the first ones weren't.
Used mine everyday for 2 months. They are rough on the grip though.

I had a couple of clips fail after a couple of seasons if that. Others here have had similar experiences.
They supply a spare clip with the lines. I'd take that as a hint.

I used mine with small sails and the lines close together. Maybe the clips got loaded less that way.

I do much the same, and I'm light. I don't remember catapulting but I probably did a few low speed ones, nothing that other lines don't take in their stride.

Tardy said, get new ones. They are what$20-25 ?
Can't you rejuvenate some of the 17 into one useable set

Late to the party. They went out the other day as I suggested I would in my response to Tardy. Everyone else is now discussing a different brand.

The semi-trailer type air hose I get is not 'coiled'.
I too have had the rope inside fail before this type of hose/tube does. 
A simple solution for low cost dependable haeness lines: Rope, + Air line tube + 4x Clove Hitches. 
For an 'easier on the boom grip' solution, sew up your own velcro/webbing attachment for the rope. 
The fixed lines with tubing and rope that let in water are a real problem. The water brings in sand, and that gathers and sits at the apex of the tubing, just where you hook in. So that sand then 'saws' through the rope quickly, often before the plastic tubing itself wears out.
When the line breaks, you then find yourself bungying off stretchy plastic tubing.
I could name the brands where that happens, but I won't.
The key is to get transparent fixed lines, where you can see if water gets in or not.

That is a problem, but I have only really had it with poor quality rope and I live in the very 'Sandy' place. Perhaps it is because my tubes are 'free' and not sewn in, so the sand can wash out as easy as it washes in
I have yet to find any really tough tube that is clear. Any pointers?
I find Flying Objects lines last the longest.
I have actually worn some out at the attachment points before the tubing or rope breaks - and that's after continual use over two years.
Credit where credit is due.
Thank Basher. Good to hear.
But I am more interested in if you have found a specific type of clear tubing that is really tough.
Well I haven't had to.
The flying objects lines seem to solve any harness line issues for me.
I've had none break or wear through for years.
