Unknown Vintage IOM Refurbishment


I got this pretty cheap. The guy said it was a IOM from Czechoslovakia. No ID in hull and various groups think it is a NAVID design. Anyway, I have no plans to race, purely a restoration for recreational sailing. I removed deck fitting and filled in holes. I ordered a IOM rig kit from Midwest Model Yachting. He helped me figure out what I needed. I received the items and man, what a challenge. I have sails in the queue as it is a 4-5 week lead time. Maybe some folks can help me out as I go along. Remember this is purely recreational sailing.

Here are a few pics.

Definitely not an IOM if it has no bow bumper. Could be a US1M as no bumper req'd, but given the country of origin, could be a Naviga class 5E which is 1m. I don't know if their old rules permitted no bumper.

I would guess it is early to mid 1980s vintage.

That single arm servo setup used for a sail winch doesn't look like it would have enough power...

For an analog arm winch, the Hitec HS815BB works well gives 140 degrees of swing.

Se this list at ServoCIty for specs -
https://www.servocity.com/servos/

Any standard digital servo with 350oz-in or better and programmed for 180 degree rotation.

eg

John's suggestions are a good start. If you want to go with a drum winch set up, there is the RMG, which is the gold standard but might be overkill for your project. There is also the HiTek drum winch and a number of others from places like Hobby King that might be suitable.
