Stripping the hull-liner

I ripped out 1/4 of the fabric hull-liner in the v-berth. I got rid of about 1/3 of the foam behind that. Rather bad pictures follow:

Pulled the fabric away from the hull. Learned the hard way that dealing with the main fabric, and the staples at the edges, separately, was essential. Bled all over the place.

The corners were tricky; cutting all needed fabric, not cutting wood, not chipping glass, not slashing myself. Whee.

Some of the foam came away naturally. But not much. The rest was glued on well.
After considerable experimentation, I found that scoring the foam heavily with the 5-in-1 was the trick. After that, you could scrape the loose bits off with the 5-in-1 ...
... and get the rest off with a spiral grill brush like this one. 2 things to note about this brush:
  1. It’s brass. You don’t want to prep any surface in a boat with steel, because when microscopic bits of steel get lodged somewhere (as they always do), they’ll rust and disrupt whatever surface you put over it. The oxidation of brass is a lot less problematic.

  2. It’s hand friendly. The bristled head is transverse to the grip, which lets me cover a lot of surface area without a lot of effort. The handle is wooden, and provides room for both of my small hands to hang onto.

The trick to my getting something like this done is to work for a few seconds, sit back and stare at it for a few seconds, work for a few seconds, and so on. It looks incredibly dilatory – even lazy – but the thing is, if I spend about half my time sitting back, I can keep this up for quite some time.

I get a lot more done in a day this way, because I can remain functional for so much longer. And it makes me stronger without provoking bad flare-ups. So far, I’ve been able to beat back flare-ups with ice and one day’s rest. That’s pretty amazing, considering how bad it was a few months ago.

Persistence, I find, is the key to success these days. Sheer blazing effort served me well … right up until it led to multiple arm surgeries. But it was satisfying as hell while it lasted. There’s nothing like tearing into a job, then turning around to find it’s done.

As I dictate that remark, I realize that the satisfaction of doing work this new way is quieter, but a lot deeper. I overcome a buttload of obstacles to do something like this, mentally picking my way through the minefield of that task until I figure it out. And then, as I do it, I refine the process more, until I figure out something that works for me and works for the task.

That satisfaction is subtle, but widely permuted: it’s the satisfaction of several different trains of thought arriving safely at their stations, and of several different physical tasks coming intelligently together to do a better job (in fact) than I had anticipated being able to do:That’s cool. That’s super cool.

Hi; I am looking to put my hull liner back up. what did you do after you took yours down? what material did you use? glue?

I'm not putting the same hull-liner back! I've been mulling over how to reline since I wrote this, and still not sure.

There are 3 main principles, one of which you'll find in books - the others are pure Piper:
- Keep airflow next to the skin of the boat. Otherwise it'll rot.
- The insulation provided by marine headliner totally sucks. Also, most of the fabrics are unpleasant to lean on (let alone look at.) You can do much better for a lot less money.
- Everything has to be easy to take down and wash. I will not let this boat turn into a mold bordello again.

I'm equally comfortable and happy in a hardware store, manufacturing shed, fabric shop, and toy store, so my solutions reflect that breadth of resources.

To answer your question specifically, here's the process I think will work best for me:

1. Insulation like the kind used on hot water heaters, which is somewhat stiff and holds a curve. 2. Then clothing-grade insulation as a padding layer, with a fabric cover on top. Almost like quilt.
3. This padded-fabric layer will have polyester "boning" (sturdy strips that hold cloth in shape) to keep the liner close to the hull.
4. The new liner will either snap in or plastic-velcro in along the boning. This holds it very securely, without rotting.

Unlike glue, this is super-easy to whip off and throw in the wash, wipe down the heater-wrap, and put everything back as good as new.

It's more effort up front than slapping down glue and making the same boneheaded decision as the builder did, but it will be a lot easier for this asthmatic to breathe when I'm done.

Not that foam doesn't have its appeal:

I'll talk to the knowledgeable folks at TAP Plastics about the longevity of these products, mold resistance, outgasing, etc.
