    Can't go much faster than that!

    A great video clip, one of the best



    Jan's little foldable boat at full speed would be spectacular sight too!

    Very nice, Arne! Looks like you had some good fun out on the water.

    One can clearly see that you sailed at about hull speed: Ingeborg sits beautifully in the trough between the first two crests of her bow wave.

    Fantastic! Congratulations! First space speed !

    My foldable "Tycia" (2.5m) reached 3,1 knots on Friday, which was a great success.

    Congrats, Jan

    Ingeborg on a beam- to broad reach

    Yesterday, on 2th July 2025
    we had another go. Again, Erik Klepsvik brought out his phone and took 2-3- videoclips  -  this time from his trimaran.

    IF Ingeborg

    As can be seen, Ingeborg is beam- to broad-reaching at around 6.0-6.5kts. Considering her hull speed of 6.0kts, she will not go much faster than this on flat water. Wind around 12kts and no whitecaps to be seen.


    Note how upright Ingeborg sails, even with the apparent wind on the beam. Later, when tacking our way home, we dropped one panel. The GPS showed tacking angles of 100-105°. Current state un-known, but probably quite slack waters.

    Arne

    PS: The GPS-trackers these days have had a sobering effect on my claims about tacking angles. One may well add 5-15° to the tacking angles shown on the compass. Still, when close-hauled on my way home, a Bostrøm 31 we ‘raced’ against, slowly dropped to leeward...

    Short  but nice video clip of Ingeborg

    It is not every day that I get to see my boats under way from the outside. Even worse, watching my Ingeborg sailing on a video is as rare as the Olympic games. Luckily, yesterday, as we were approaching Lundsvågen Harbour after an Around Hundvåg ccw, a sailing mate Erik Klepsvik stood on the mole and took this little video clip. The wind was fine, some 12-14kts so I guess we close-reached here at about 6kts with one panel down.
    Now, with a clean bottom on Ingeborg, we welcome the summer...

    PS: And yes, Around Hundvåg was clocked to 1:42:46, and top speed (downwind in a wind gust) was recorded to 7.1 kts.
    Not bragging, just mentioning it...

    A video-clip of Ingeborg sailing

    Last Friday (2. Aug. 2019) we in Ingeborg had a rendezvous on the fjord with mate Erik Klepsvik in his six meter long Jewell, a plywood-built yawl, designed by Francois Vivier. That resulted in a number of photos of his fine boat. Now, he has put together a string of short video clips of Ingeborg, and sent to me. I stored it on my ‘little cloud’ on Dropbox:

    https://bit.ly/2YRnCNN

    The wind that day was light, at around F3, and for once I could make use of full sail area the whole day. Our speed on the clip is between five and six knots, I guess.

    The video is rather low-res and not spectacular in any way. However, at the end of it, one can clearly see how moderate the twist is in her sail. That underline what I wrote in my posting below, last year.

    Cheers, Arne

    Single or double sheet.

    One thing puzzles me: Why does so many junks sail around with 4-, 5- or even 6-part single sheets?

    All my boats have had 3-part sheet, either the Pilmer or the Johanna version (see p. 4-5). Only once did I start with a 5-part sheet and that was on Johanna’s 48sqm sail. One single trip. I found that the sheet added too much friction while hoisting sail, and in the very light wind, during that trip, the sail was reluctant to pull the sheet out through all those blocks. Last, but not least, that 5-part sheet added up to a lot of spaghetti in the cockpit.

    I am much happier with the 3-part (single) version, even though it can be a handful to haul in on sails over 30sqm. Then I have the choice between cranking in the last bit with my genoa winch (Lewmar 8). The forces are light enough to let me crank the winch with one hand and hauling the end with the other. The other option is to simply head up for a second, pull in the slack sheet and then fall off again.

    To me it appears that controlling the twist in the sail is vital to getting most out of the sail. Most sails end up with too much twist much of the time. My H-M sails with a full size fan top all seem to like the Johanna-sheeting. That may be over the top on flat-topped sails, so maybe the Pilmer version is better.

    I have seen double (upper-lower) sheeting on one sail; the schooner Samson’s 70sqm mainsail. That appeared to make sense. In light winds, the skipper just grabbed both ends and hauled in. In stronger winds he could haul at one end and then on the other.

    However, on Ingeborg’s little (35sqm) sail, it makes little sense to me to split the sheet. The twist stays quite right both with full sail and when reefed.

    On the other hand  -  if there is very little room for the sheets, a double version may be needed, both to save space (D-min) and to control the twist.

    The photo below shows Ingeborg leaning to the breeze, using the Johanna-sheeting.

    To do or not to do a fan-up

    I have never experienced a fan-up with any of my rigs. However, I have no wish to do so either, so fitting some sort of FUP makes sense to me (I haven’t crashed my car either, but still think using the safety belt makes sense).

    Actually, I strictly don’t need the FUP, as for my sort of sailing I don’t have to make long gybes if I don’t want to. I more often make my gybes short, or I just round up and tack her around. My playing with the FUP idea is therefore more a result of curiosity, and I then thought it could be useful as a ‘safety belt’ for offshore sailors as well. I have Bob Grove’s experience in mind.

    From a fanning-up point of view my sails are nothing but H-M sails, of which there are hundreds sailing around. Most of them have never had a fan-up (including Badger?).  Even if my armchair guess is that flat-topped junksails are less prone to be grabbed by the wind and thus fan up, they are not bullet proof in this respect. In the ‘right’ conditions, the top section can be flung over in a violent roll, unless some sort of downhaul is there to prevent it. My FUP is my suggested version. I guess that Slieve McGalliard’s  combined batten parrel/downhauls have a similar effect.
