First impressions, the first things to sort out and a plea for your advice (also, if you spot something on the video, don't be shy to point it out, please!):
1. The mast went in like a charm. Looks like - despite my fears - I got the measurements right and the mast stands straight without significant fiddling with wedges. Phew!
My wedges are made of softwood, and I used a hammer to install them. Can one be too hard with this? Is it possible to harm a 5mm aluminium wall with softwood wedges?
2. I put more significant stress on the mast than was wise on the first sail, but so far the mast itself, the mast top/crane, wedges, partners and step seem fine. I didn't notice but some minor squeaking of the wedges for a few times. This surprised me. Or did I use too much violence (see #1)?
3. It seems that one should reef for following winds and waves sooner than anticipated with the wind itself; this might be true to all JR boats with a heavyish mast very far forward, though.
When the sideways motion starts, it easily becomes very aggressive. This is probably known by all of you, but for me this was new and a bit frightening. I have to teach myself to drop enough sail area before I find myself in these conditions.
Thankfully the Galion's rudder coped with all situations.
4. With all the tweaking of the sail still to come, I am very pleased with the performance close-winded. We sailed through the archipelago with narrow passages, rocky waterways and heavy leisure traffic, and I was happily surprised that practically all situations were cleared without the motor, thanks to the windward ablity and super-easy tacks.
A rough estimate from the gps track (I have no excact intruments to do better) suggests under 90 degree angles already. The Galion is a very close-winded boat with BR, and it seems that a lot of it has to do with the hull shape.
5. I had a problem with the halyard block or the YHP block on the yard hitting the mast and in some cases making scratches on it. How does one keep the slingpoint/s away from the mast in all situations?
6. A few times the panels got stuck while reefing. The batten parrels might be too tight, the temporary padding material (garden hose) too sticky or the problem is something else (what?). This has to be sorted out - I would't like to add downhauls and the complexity with this.
7. With the sheet let out for following winds, there was too much twist for my liking, especially with a reefed sail. I think there was something wrong with the way I rigged the mast lift and some other ropes that hindered the free movement of the boom - or I might have a problem with the sheeting arrangement.
I used Arne's Johanna-style sheeting. The length of the sheetlets were more or less based on a guess, I haven't got the experience to find out the optimal lenghts yet.
8. The typical diagonal creases are there. I will first check the slingpoint/s on the yard, the batten parrel lenghts/tightness and sheeting, then maybe add a simple THP. Hopefully this helps, because I did a lot of work with the shaping of the panels; I would like to see the camber properly, no matter if it affects the performance or not (like Annie suggests, shhh).
9. The sheet is everywhere at the cockpit. I might need to build the lazyjacks as running, along with the mast lift to be able to make the first reef upwards. With a full sail the boom is quite low, which fills the cockpit with rope during a jibe. I could live with this, but the sheet seems to like to tangle especially on the tiller. This indicates a possible catastrophy.
