My faithful 3M 6800 series full face respirator has been literally rotting away and is no longer fit for service- the rubber straps that hold the faceplate to the face were rotting/crumbling/breaking into itsy bitsy pieces. I once rebuilt the respirator, ordering all the parts it needed but the hassle of finding and ordering the bits and pieces wasn't worth the effort so I simply bought a new one.
Some may remember that on my last haul-out day, I got pinned against a rock and the only way to clear water was a dance through a whole rock garden. That left a few scars.
Yesterday was really the first time I took a really good look at the scars. Luckily, most of the scarring was only into the fairing filler from the last repair. There were 3-4 spots where the fibers had been scratched and one spot that was really 'damaged' in the true sense of the word.


When I bought the boat I discovered water dripping out of the hull from a boat that supposedly hadn't seen water in 2 years. After some investigating, it turned out the boat had run up on something and repairs had been made (poorly) using a polyester filler material. Water had wicked up through the polyester filler into the cracks that had not been completely removed, once I started removing old bottom paint the water started seeping back out.
I repaired that bit and added a few extra layers of 15 oz. biaxial cloth figuring the boat is likely to hit something again and a little extra wouldn't hurt. I was exactly right about that. The recent damage penetrated into the extra layers I had previously added but didn't get into the original hull structure.
blah blah blah....
Anyway, I used my grinder with the flap wheel attachment (overlapping sandpaper arranged like a fan on the grinder wheel- great tool) to dish out the damage.

Then I started adding new material. The weather felt warm but in reality it was a lot colder than the weather I usually do composite work in and I was grossly optimistic as to how long the epoxy was going to take to kick off. I spent an hour watching my first patches slowly try to pull off under the weight of gravity. Eventually the epoxy did kick but I was too scared to put on a second layer that day for fears the extra weight would pull the whole thing off. I really really want a vacuum bagging setup. Maybe for the next boat.
So the slow epoxy took up a lot of time. I also pulled the panel from behind the toilet and altered one of the holes for the hoses that come out for a better fit. Then, because I hated the painted plywood shelf I had made for the storage area behind the toilet, I cut out a new shelf with some pine I had left over from the settee storage locker shelving. I am much happier with the looks now.
I am sure I did something else on Saturday but I can't remember what it was now.
So Sunday, I applied a second layer of material to my patches but this time I applied clear epoxy to the damaged area and patches and then waited 20 minutes before applying the patches to the hull. That worked much better and the patches gripped within a few minutes. Much easier.
After that, I decided I needed to try and recover as much of the hardware that fell into the bilge a few weeks ago as I could. There was a lot of dust in the interior at one point and the bilge still manages to collect it along with some water which leaves a nice slimy mud in the very bottom of my deep bilge. I thoroughly enjoyed vacuuming up all my hardware out of the bilge and attempting to clean it all up. And I only spilled a little mud in my cockpit...
There were a few bits and pieces projects that got done but hardly worth the mention. Oh, and the poorly made patch from the old fuel fill fitting (I take full responsibility) got a workover this weekend. I decided not to hang upside down with a grinder in the cockpit locker and instead drill a few holes and injected thickened epoxy into the gaps in the bad 'glassing job. Then, where the deck had started to crack, I opened up a small hole and injected some more thickened epoxy. Its ugly but solid now. I was only worried about it because its about six inches forward of the jib cleat and I didn't want the cleat to depart taking a section of the side deck with it. Knowing me, I probably won't be happy with what I have done and I will hang upside down in the cockpit locker with a grinder and do the job I should have done in the first place...
and that about sums up my boat work for this weekend. The slow epoxy meant that I couldn't complete the patch job on the hull. I will clean up the patching next week and add a layer of 1.5 oz. cloth and epoxy with sandable fairing filler added. I want to add the 'normal' glass because it seems the filler from the old repair wanted to separate right where it attached to the biax and I think a layer of regular cloth will make for a better bonding surface. Who knows. More fibers is always better right?

Aren't you glad you don't have black bottom paint anymore?
