I spent the morning doing more rough-fairing of the hull. I'm just about done. Not super happy with the results - just too hard to get things looking nice when you're sanding both foam and bog. Not looking forward to the real fairing.
After I got 95% done on the fairing, I decided to do some lamination work, starting at the aftcabin. I laminated the cabin top, the gunwale\hull-sides below the aft cabin, and also did the uni-glass for the aft cabin. Here's a rare intra-lamination picture; I'm wrapping this piece of glass around the hull (foam is pre-bogged & wetted, so the glass sticks nicely) preparing for further wet-out:
Here's the uni at the rear of the cabin:

I climbed up into the boat for the first time today and sat in the cabin - then fell under the "sailing daydream" spell. Felt really, really good to see what I've accomplished so far. The cabin feels roomy to me, even with the daggerboard case. I can tell that I'll have to be very careful walking on the cockpit floor - it's quite "spongy" under my weight. Best to keep my feet near the hull sides where the fillets and tape are.
I lost some time yesterday to a household plumbing emergency (leak) which kinda sucked. I've been working on rough-fairing of the hull foam - as usual it's difficult wherever you have bog sticking out. I'll do the best I can but will then leave it up to the fairing to make it look good.
I finished up the day with some shop cleanup and made a run to the dump to get rid of accumulated debris. This was needed to make more room along the starboard side of the hull - was getting tired of ducking under the gunwale:
I like his boat naming scheme, ie "Osram I", "Osram II", etc. I still haven't come up with a good name for my F22.

Obviously one cradle is for form frame #5, and the other for #8. I measured the distance from the hull bottom to the gunwale line at each of those locations and built the cradles so that the hull would be positioned roughly to make the gunwale lines level forward-to-aft. I'm not expecting it to be perfect, but hopefully it will get me in the ballpark.
Later my neighbor came over and we got the hull lifted up again and positioned in the cradles, on top of the strongback:
Eventually I will remove the strongback and put the cradles directly on the ground, but right now it makes a good level platform for installing things like, beam mounts.
I am thinking about making another cradle to support the transom. Although in theory it won't be needed after the exterior lamination is finished and the beam mounts are installed.

No sounds of creaking or other distress from the hull so I'm assuming all is well. I rough-faired the lower hull foam and got ready for laminating. Here I'm rolling up 22 feet of 'A' glass on a tube:
And all finished:
I made sure I had the requisite 2" overlap at the join seam; usually it was more like 4-5" overlap, but in the heat of battle (laminating) I just wasn't willing to stop and trim things up. The keel is a good place to have a little extra glass anyway.
Our dog "Beau" was out supervising for part of the time; he's a 9 1/2 year old boxer:
Tomorrow I need to build myself some main hull cradles. Then in the evening my neighbor will help me hoist the hull back up and then lower it into the cradles. After that I'll start fairing the edges of the deck and gunwales and get ready for finishing the exterior lamination.

Fortunately one of my neighbors was willing to help me out, and he already had the necessary lifting equipment. Thanks a ton Sean - I couldn't have done this without you. (He was also much calmer than I was, since I had visions of fallen\smashed boat dancing in my head most of the time.)
Without further ado, here's some pictures; this is a lift strap tied around the hull:
After achieving lift-off with just one strap (located at the rear main cabin bulkhead), we got busy removing form frames starting from the transom moving forward. The battens were cut away piece-meal from below using a cutoff tool, then were broken off as needed until each frame could be removed:
In the picture above, the boat is indeed being supported from above, but the clearance above the battens is quite minimal (we didn't have a lot of lifting room due to the low clearance at the top of the tent).
After removing up to about form frame 5 or 6, we attached another lift strap at FF #5, and picked up the remainder of the boat. For this we used a chainfall tied to the bottom support rail of the tent:
I had picked up some cheap used baby mattresses from the local thrift store to use as padding under the side of the boat. Should have gotten more though, since I didn't feel comfortable laying the gunwale down without any padding. So we left the boat semi-suspended for the night:
I made another shopping trip this evening for more mattresses. Tomorrow we'll finish laying the boat down on its gunwale, and then I'll get busy fairing the rest of the bottom hull half and preparing it for lamination.

Next was the starboard settee; here it is set into position so I can tape the backside:
After all taping was done:
I've decided to double the foam thickness after of the transom\aft-cabin, per the option described in the plans. I'm a big guy and I'd like the boat to be as strong as possible. Here I'm taping over a extra layer of foam that I glued to the lower portion of the transom:
Trial-fitting the mount:
I first tacked the mount into position with a heavy layer of bog on the bottom of the mount, then let that cure (didn't want to risk it moving around while I was taping). Here's some of the mount taping:
Finally, here's the rear deck all closed up and taped:
Doesn't seem like much for two days work, but I am really glad the rudder mount is in. I've also removed 90% of the remaining screws holding the hull to the battens. I'll finish that up tomorrow, but I think I'm now ready to remove the hull from the frames.

I made a mold plate for the fwd bunktop, out of scrap wood:
Here's the fresh flanges\tape after the mold plate was removed:
Finally, I got up early this morning so I could laminate the lower port hull half. Tried to do it myself, but I haven't figured out a good way to manage the roll of glass as I'm working my way down the hull. Fortunately my daughter was home and helped my out - thx Cindy!
I plan to wait to laminate the bow until after I have the hull upright.
View from aft (glass is kinda moving up and down due to my difficulties in managing it, until I got my daughter to help):

Then I started fitting my daggerboard into the case. Here's the (not yet fully faired) board sticking out the top:
Here's the "A" daggerboard section traced out on the bottom of the case:
The poured-insert turned out pretty thick. All of the chopped glass I added to the mix settled to the bottom of the insert though.
The hole turned out to be too small (I was worried it'd be too big), and I had to gradually enlarge it. I tried various tools but finally settled on a round rat-tail file. This was good for increasing the opening while keeping the curves nice and even. To be honest, there's not much left of the insert by the time you get to this point:
