Fiberglass does absorb water given time; up to 3% of boat weight can be drawn into the matrix. If you left a boat with water standing inside it during the warm months, some may be absorbed Hi Rich I pull off my deck patches between regattas, and the hull breathes and seems to dry out inside quite w...

It sails very well in light air, but when the wind comes up over about 5 knots, it gets a bit tough to keep up with trim. It shows strong weather helm in the puffs, and is sensitive to mast rake. I was involved with some "Highlander" designs a few years ago, and Steve's advice is spot-on. Adjusting...

I found this on Ken Binks' site at http://www.kbits.co.uk/ : Hitec adjustable Drum Winch HS-725BB Price : GBP 54 Catalogue #: WH.005 - Torque 14.5 Kg/cm - Speed 1.13sec/360 deg - 6.0 volt - Throw adjustment: modified by KBits.. to give 1.5 - 4 turns Ken modifies the winch to add a variable resistor ...

The IOM forum is happy to host special interest groups for IOM sailors. For example, we have the "Nordic SIG" usergroup, comprising IOM sailors who wish to promote the "Nordic Cup" (a competition involving DEN, FIN, NOR, and SWE). As a general guideline, the SIG should have an international dimensio...

... can you measure the current the winch draws when you test this? Hi Anders What I normally do is charge up a battery to a known capacity, go and sail and measure the total time spent with the radio system on, and then measure the remaining capacity of the battery afterwards by discharging it ful...

One of the problems at the 2003 Worlds in Vancouver (and I think this can apply for any course layout) was a couple of races when a mark was so far away that you could not read the numbers on the sails as the boats rounded. Now IMHO that mark was too far away. So this would be one of the constraints...

Gyula Ferencz has told me about an old trick to increase arm winch torque to around 175% of rated amount! I'll be trying it in a couple of weeks, and here is the spreadsheet: http://www.onemetre.net/Download/Cam/Cam.htm

An idea that has been suggested is as follows. Allocate the 47 available frequencies to the first 47 seeded sailors. (In the UK, we would simply take the first 47 names on our national ranking list in order to seed.) These frequencies are then known by the name of the seeded sailor using it. For exa...

To see if you have a private message, look at the top of the screen after you have logged in. You'll see (shown in the red box for illustration) "You have X new messages", or "You have no new messages". This is a rather subtle notification arrangement, and it is very easy to miss the fact that you h...

The Class Rules are specific in terms of number and thickness of Sail Shape Indicator Stripes. This being so, I have to believe the limitation is in the interests of keeping the sails tidy and the numbers/other identification clearly seen. Hi Roy I'm not an "official" expert on the class rules, but...

The Events sub-committee can only select and approve from the bids which are made, of course. Over the last years, bids have been rather thin on the ground AFAIK. But the current trend for the Worlds is looking good -- Europe 2001, Americas 2003, Oceana 2005 -- so that is spreading it around... In t...

Would it be a Topping Lift? Hi Steve IMHO it isn't a topping lift, as you say, because the sail is supporting the boom. It'd be interesting to know the correct term for this line! "Reverse topping lift" is a possibility, but doesn't seem quite accurate, since the line isn't supporting the fore end ...

The old Yahoo discussion group for owners of the IOM is now closed. The old messages remain there for the next few months, as do the old files. If you want to save anything, now is the time to do it. The group will thereafter be deleted. Peak group membership was 229 members. Thanks, IOM sailors, fo...

Was sailing with Graham Bantock and Ken Binks at the Brentwood club's "Icicle" event on Sunday (they finished in that order, Peter Stollery third, yours truly fourth). Graham said that the new SAILSetc catalogue and Web site (in about 4 weeks) will feature an arm for this winch with adjustable attac...

If you plan on using a 5735, use the programmer to slow it down - it is way too fast. Hi Rey It certainly is fast. Ken Binks tells me that is one of its very strong selling points. It allows you to execute a "flick gybe" without touching the rudder. I've won more than one club regatta recently by b...

Looked at a couple of sailing dictionaries. In essence, a topping lift is a line that supports the boom when the sail doesn't.

can that formula be used for the forces required for close haul sailing ? Hi JohnB The formula is good for obtaining the amount of force exerted by anything with some area A moving at a given speed S through some medium of a specified density rho. Close-hauled, looking to calculate the lift force o...

Do change the winch in your boat according to the weather you are expecting?? Hi Nigel Er, nope! I run the 1/4 scale winch at all times, not too concerned with its weight since this is very similar to a RMG, which is the winch I used previously and would return to if the arm arrangement disappoints...

Rob Davis wrote:Do the ICAR Rules have any further relevancy to the IOM class?

Hi Rob

I'm pretty confident that they are no longer relevant. AFAIK, the only class that references them is the "A".

has anybody ever done some detailed research on the sheetingloads on our boats :shock: <CENTER> http://www.onemetre.net/Download/Armwinch/Armwinch.jpg </CENTER> Photo ©2002 Ken Binks Here are some rough calculations.

would something in the range of 12 Kg have enough power Hi Nigel The torque of 21 kg.cm from the 1/4 scale Hitec digital servo is only enough to sheet in on my Italiko when the wind speed is under 4.5 m/sec. If a gust comes in, I have trouble. The smaller servo with 12 kg.cm IMHO won't handle it at...

As Anders notes in the "Arm winch" topic, the recent "IOM Interpretation 2003-4" has, amongst many other fascinating matters, made it clear (in my unofficial opinion!) that The mainsheet, and the jibsheet, can be attached to separate points on the arm, but only one control line is allowed. Now a "co...

Hi IOM sailors For my sins (which are clearly considerable!) I've been asked to be the Race Officer for the GBR IOM Nationals in 2004. One of the problems that worries me is frequency management. We have about 47 frequencies we can use in GBR, but we could have up to 84 competitors sailing in 5 heat...

Hi IOM sailors Here is a question -- should IOM championships follow the new ISAF instructions for Olympic regattas, and remove discards from the scoring system? After considerable debate, the ISAF Council decided that at the 2004 Olympic Regatta there will be no drop races in any of the events. htt...
