    Lovely photos Arne.  That sail looks quite big enough to me!  I went sailing aboard a bermudian-rigged IF the other day (exactly the same as yours but built here).  The winds were light and we only had the working jib bent on, but the boat slipped along so sweetly, with just the slightest touch of weather helm (I was holding the tiller with two fingers).  I've always loved these boats and that sail increased my affection.  I might not be able to live permanently on one though, unless I had a storage shed ashore!

    Thanks, Annie.
    Luckily, I found that I could throttle down the Tohatsu quite a lot before the speed dropped to 5.0kts, so it must be that the speed-drag curve is rapidly getting steeper over 5kts (theoretical hull speed is 6.0kts). 

    I guess 5kts will be the cruising speed under motor  -  that is after all a decent sailing speed for such a small craft.

    Arne.

    Arne, I have never, in my life, owned a boat that would motor faster than 5 kt.  I find it reassuring that your Ingeborg will motor at 5.5 kt with the same engine that I'm fitting to SibLim.  She'll probably end up faster than Fantail with her 10hp diesel engine!!

    A chilly April outing in Ingeborg.

    Yesterday a friend, Erik, sailing a big ‘Storm 19’ dinghy from Swallow Boats, called me and wanted to meet on the fjord for a little photo session. That suited me fine as I was on my way to the harbour.  Hopefully, this link to this Google photo folder lets you see the result.

    https://photos.app.goo.gl/WDNAXke4NV2nxMLJ6


    The wind was 10-12 knots, I guess, just below needing the first reef. On the photo below we were making 6.2kts. It is amazing how my boats have (had) different characters. While the ballast-less  Frøken Sørensen would have been nervous, but fast in the conditions, Ingeborg  just leans over and romps along. Her 50 kg mast and around 40kg sail seem to be no problem, as she attains just below 5 kts when close-hauled. Her short waterline length with no overhangs puts limits on the top speed, though. At 6.05m it only lets her go at 5.5kts with the 6hp Tohatsu, compared to 6.3kts when my Johanna (wl=6.8m plus overhang) was pushed by a 9.9hp Yamaha.

    Still, Ingeborg is a lovely boat, and probably beats every boat I have had when close-hauled in some wind. I sometimes wish I had given her a 40sqm sail for the light summer winds. Compared to when sailing Malena (wl 6.00m, 1400kg, 32sqm), it feels like sailing with one reef...

    A final thing: The FUP line now works fine without getting jammed as the sail is furled. Still, on a sail with heavier battens, I can see Graham’s point in having a two-part FUP, to minimise friction.

    Hi Arne.  Your drawing looks intriguing and I will have to think about that.  I was intending to take the upper FUP straight from A to C, then forward to D like the lower FUP.  You may be right that the small saddles were the cause of the problem.  It was easy to take up the slack for the lower two panels, but after that the line seemed to get trapped by the nested battens, which fall randomly, one this side, one that side etc.  I think the FUP has a lot of potential though and is worth sorting out.  You can stop fan ups when doing intentional gybes, by hauling in the sheet and doing a controlled gybe, but that still leaves accidental gybes in rough conditions, which are not uncommon when rolling heavily under self steering in rough seas, or in sudden wind shifts..  Besides, it will be nice to gybe with a slack sheet when you wish to.

    Graham,

    Is this what you have in mind, or was the upper FUP also meant to be passed over blocks C and D (instead of B and F)? I think the way I have drawn it, will give the best guarantee against friction traps. Anyway, I think the main friction problem stemmed from you using those small steel saddles.

    For my own part, I will try out my modified, single FUP system. If I still get friction problems, I will change it to your version.

    Hi Arne, that is interesting news about your FUP developments.  I am a big fan of the FUP, but unrigged mine due to the line getting trapped.  I could get it to render usually but it was a struggle and I was concerned for what it might be dong to the stitching on the sail.  But I am going to rerig a version of it again before going cruising this year (about the end of May I hope).  I am going to use two lines of different colours, one starting at the second batten up from the boom and one from the fourth batten up.  Both will come back to the same cleat so can be hauled together.  They will pass outside of everything on the sail.  The idea being, if I only have one panel reefed, I wont be worried about a fan up, especially with the slack taken out of the two lines.  When two panels are down, the lower line is snugged up tight and those two battens cannot go anywhere.  The upper line has the slack taken out of it.  Then the third panel is not a problem since the ones below it cannot lift, and when I get the fourth panel down, both lines are snugged up tight.  That only leaves the three fanned panels, that can come to no harm if they fan up, and I am unlikely to be more deeply reefed than that when coastal cruising and picking my weather.  If I was crossing oceans, I would also put a downhaul on the yard.

    Reducing friction problems of the FUP (Fan-up preventer).
    (Also see posting on the FUP subject below, in October 2017)

    Today I made use of the calm weather to partly hoist Ingeborg’s sail in her berth. I had already prepared two strings to replace the aux batten parrels on batten 3 and 4. The idea, as shown on the photo, was to make them slacker and thus reduce the chance for the FUP-line to be trapped between furled battens. In addition, the FUP line is now skipping batten 5 and 6.  As mentioned before, the line is now also passed outside the lazyjacks. Together this should reduce the chance of having the FUP line trapped.

    To be dead sure it will never happen, one has better taking in the slack FUP line as the sail is furled. This is what we do, anyway, during sailing, as we reef one or two panels at a time. I guess we will have to live with this little hassle that the FUP adds. I will much rather deal with that than having a real fan-up to deal with.

    Your choice.

    Arne

    Annie,

    no, the drogue was towed from the stern, or from the lee mooring bit to be more precise. I never left the cockpit after dropping the lines in our berth. I have fitted that drogue with a permanent line, only about 4-5m long, and with a big bowline loop at its end.

    As we motored out of the inner harbour, I slipped the bowline over that port stern bit, so when we were out in open water, I just put the engine in free and tossed the little parachute over the side. With the line pulled out, the parachute opened instantly. Without a drogue, Ingeborg (just as Johanna) would coast forever, but now we were slowed down to drogue speed in a couple of boat lengths. The GPS showed that we stayed below 0.5kts (0.1-0.3 mostly). Best of all, when the sail had been hauled up, the parrels trimmed and the halyard stowed in its bag, we had still just covered a fraction of the bay. The little forward motion was still enough for Ingeborg to maintain a beam to close reach with the tiller locked a bit to leeward (as on that photo).
    A bonus was that I only needed the smallest parachute for this particular job. At a square section of only 0.125sqm, it is not more than 1.5 times the area of a big bucket.

    I made one of that parachute’s six sections from a different colour to see if the thing rotated under load. However, it stayed so deep and I was too busy at the halyard, so I never noticed. Still, it cannot have spun fast, at least, for when I recovered it after raising the sail, there was no sign of twist on the line.

    Halyard hauler! Thanks, Annie, I wondered what to call that thing.
    No, my hands are not big. On earlier boats, I used ropes with multifilament in the outer layer, as that was so easy to grip. However, I also found that they were worn rather fast, so changed to monofilament ropes, which have proven to be much tougher and which also seem to run more easily through blocks. On the small boats, Broremann and Frøken Sørensen, it was still easy enough to haul, but on Johanna (48sqm) and Ingeborg (35sqm), I found it annoying, even with gloves. I still have the electric winch handle from Winchrite, which works perfectly well, but I like the idea of being able to raise the sail by hand, at least now and then.

    Gosh, Arne, what an inventive mind you have! I assume you used your drogue over the bow.  It seems like something that will be useful for you to have.  The halyard hauler will be a boon for those with big hands.  The one time it's an advantage to have hands the size of mine is when I am handling 8mm rope: it's very comfortable for me!

    Glad to hear that spring has sprung for you.  And that you are showing a clean pair of heels to your fellow sailors.  Ingeborg sounds like a joy.
