Hi,
My comments below;
: it requires a different hull shape. I am curious about your KOG77, it
: looks very nice. I will check it out.
Yeah, from the looks point of view, #77 should be soo pretty. And I guess the speed should be nice too in usual paddling speeds.
(about Baidarka)
: But their bow is fuller and the hull is more rounded which should be more
: efficient. I also think that a narrow chine splits the water too gradually
: which makes the wave length that fits effectively around the hull,
: shorter. Thus the speed is lower, too. Speed daemons usually have a boxy
: look, zero rocker, rounded hull with full bow and stern profile.
Hmm, round hull does not help so much. Difference should be quite little compared to chined hull. Especially if you take stability in consideration too. The fastest baidarkas do not have really round hull, there's angle like in greenland model to keep the kayak narrow.
: Thanks. I like the shape too, maybe I will build it as is. The Kaper profile
: was not that different from my current kayak (below) which is OK. And
: thanks for your advice regarding using Kaper directly, too. For now it is
: a bit too much to take on but others did it, like KayakFoundry.
If I look your kayak and the fast greenlanders, I think your's have quite much rocker if you really aim for high speed. But I don't know what your high speed really is, so it's a bit difficult to comment on that area. Also the waterline doesn't look so narrow...
For kog#6 at 90kg (198.4 lbs) displacement I'll get with Kaper:
+------+-------+
| Speed|Spilman|
| [kn] | [lbs] | KOG #6
+------+-------+
| 2.00 | 1.003 | 0.80
| 3.00 | 2.175 | 1.75
| 4.00 | 3.818 | 3.12
| 4.50 | 5.071 | 4.23
| 5.00 | 6.950 | 6.00
| 5.90 | 13.19 | (11.24 at 5.80 kn)
+------+-------+
Making a Freeship model from views is quite fast. If you want I could make the model and run it through Michlet to see how it compares against traditional Greenland kayaks. In case you didn't know that, I'll include the link below.
