IOM sail camera videos

Looks like the mast bends to leeward at the middle, while the top of the mast stays in place. I don't think that's a good thing. Should try lower shroud attachment point and maybe shorter spreaders. Remember to turn up the sound so you hear the wind, water, and the RMG winch! Also try these [...]

IOM Sail Camera

Jari got a Hero camera which takes still pictures and video and stores them on a memory card. It weighs about 120g and it's watertight, so it's possible to put it on-board and take some pictures while sailing. Seems to work quite well. This could be used later for looking at how the mast bends [...]

KLV IOM ranking race

10 boats, including two guest sailors from Russia with Naviga one-metres, completed 12 races in varying no1 rig conditions. The pictures show some cnc-milled aluminium fittings by Jari Immanen, and Oleg Konka's RUS-32, a Naviga one-metre built by Janus Walicki. Note the rudder. The forward section has an airfoil shape while the aft half of [...]

Bulbs of Steel

As a first serious test-run for our now servo-controlled cnc mill we decided to make an IOM bulb out of steel. It ends up a bit bigger in volume when made out of steel compared to lead, but the difference isn't huge. Making it with a cnc mill allows designing almost any reasonable 3D shape [...]

Widgets for Sail

Graham Elliot from the UK doesn't have a website of his own (yet?) , but wanted to let everyone know that he is now building and selling the Widget IOM. Designed by Chris Dicks in 1995 the boat has gone through quite a few changes to everything except the hull shape. The Widget has won [...]

IOM Worlds report in Pienoismalli

I wrote a short report from the Marseilles IOM-Worlds which appears in the latest issue of Pienoismalli.

Sepktrum DX6i, HiTec HSR-5990

Spektrum recently introduced an updated version of the DX6: the DX6i. Horizon Hobby also has an article on the new radio. This one uses 'DSM2' technology which is described as giving 'full range'. Not sure what that means, but range should be better than with the first generation of 2.4 GHz radios, which at times [...]

More Marseilles pics

Here's David Potter's GBR20 Lintel. Note how high the gooseneck is. The boat is not so fast in light weather, so this is an attempt to get the rig higher up and gain some speed in the light stuff. Home-made gooseneck with laser-cut stainless steel bearing holders at the top and bottom (note adjustable holder [...]

IOM details from Marseilles

Here are some detail pictures from last week that I thought were interesting. Graham Bantock's Topiko. Note quick-release bottlescrew and deck-fitting far right. Also note how the cunningham is threaded through a plate with holes around the mast. I think this gives a variable cunningham tension (tight on the beat, looser on the run?) Recessed [...]

KISS IOM Construction

(click image for high-resolution version) The current Noux Mk2 construction is obviously too difficult to put together. There are lots of separate mouldings that need to be fit and bonded to the hull, lot's of sanding, filling, and painting. So I'm trying to think of a simpler design that would be easier to build. With [...]
