building an iom rc yacht

This site is primarily intended to help those building a one off IOM (International One Metre) or a similar radio controlled model yacht. Essentially the hull and decks can either by built in Glass / Epoxy throughout, or in Wood - typically Cedar or Balsa (balsa needs glass sheathing), and with a very thin ply deck.

Where you are intending to build a few similar boats, for example a group of you want to build the same design, a female mould of some form should be made. This is not dealt with here.

BUILD, SETUP, TUNE AND RACE AN INTERNATIONAL ONE METRE (IOM) YACHT

Frank Russell Design

R/c and model yacht design, plans, boats, sails..

New Equinox IOM   Plan : The Equinox is a variant of the Ellipsis… IOM.  The basic  design was produced initially as a 3D printed project that never eventuated for various reasons. Two prototypes were built including a 3D printed boat which was built by John Taylor in the UK.  The design incorporates several features of some of the newer IOM shapes including a fuller higher bow profile and wider stern. The design is well balanced and well behaved like the Ellipsis and also should be as easy to plank from wood.

Hulls an components for this design are now available. See IOM COMPONENTS  Page.

After payment is made. I will email you the pdf file.

Please ask If you require another format: DXF, or DWG, 2D or 3D or printed paper plan, postage extra.

Equinox IOM Basic Hull and Deck STL: This is suitable for turning into 3D drawings for 3D printing. Can also be used as is for CNC.

Builders should be aware that you also need to purchase the plan of the Equinox IOM to build the boat as the build licence is attached to the plan not to the STL.

Equinox IOM 20 section laser cut sections: less 3mm for planking with building base included.

You should be aware that you also need to purchase the plan of the Equinox IOM to build the boat as the licence is attached to the plan not to this drawing.

Ellipsis… 2017 IOM is the 2017 fresh approach to IOM shapes. The chine is gone, The tumble home is gone, but the volume distribution and excellent hull balance remain. This is a powerful low wetted area, narrow waterline shape. Two alternate deck designs are offered. 10 section Laser cut sections less 3mm for planking are included.

Hulls an components for this design are now available. See IOM YACHTS Page.

If you require another format: DXF, or DWG, or printed paper plan, postage extra.

Goth Mk4 IOM is the 2015 development of last year’s Goth XP Plan and incorporates ideas borrowed from the Goth XP RG RG65 design.

Some IOM bulbs from the new moulds .

New IOM bulb moulds cnc-machined

Jari made these new IOM bulb-moulds over the weekend. CNC-milled in aluminium. Circular cross-section with a NACA0010-34 profile (similar to my 2005 design ), length ca 360mm. Designed with a central stiffening brass rod. Check out rcyachttech .webs.com for more cnc-machined moulds and parts.

See also casting notes from 2003.

RC Yacht Tech

Jari Immanen now has his own website at http://rcyachttech.webs.com/

Monster servo mount

The new high-torque winch servo is 44x22mm instead of the standard 40x20mm, so we made a new radio-plate for it today. The new plate has a bigger cut-out for the new servo, and is slightly wider. The boat will sail again next weekend so we will hear how the new servo works then.

CNC-turned stainless steel IOM bulb

CNC-turned from stainless steel, this is a 400mm long and 38mm diameter IOM keel bulb. A slot will be milled in the middle for the keel fin. Unlike a lead-bulb this one will require no surface filler/sanding/painting. But the density (compared to water) of stainless steel is 8 at most, while lead bulbs can be close to 11 (depending on the lead-alloy), which means the volume of this bulb is slightly larger.

PIKANTO hull Nr 1

We've moulded the first PIKANTO hull!

This is a bit of a prototype since it's some time since Jari or myself moulded a boat, and also because these are brand new moulds and we have never made a boat in one-go like this before: closed mould with the hull, deck, mast/finbox, and ruddertube all attached in one session. We need a bit of routine and practice to get the whole process of "release-agent > gelcoat > resin/fiber > fin/mastobox > close-mould > seal deck-joint" running smoothly. I am sure by hull nr 5 or so we will have learnt the workflow pretty well 🙂

Having said that, this first prototype hull came out of the mould pretty good. There are some problems with an uneven gelcoat layer, and a few places in the foredeck where there is trapped air between fiber/gelcoat. We're considering either cutting away the rounded flanges on the foredeck, or alternatively moulding the deck from many smaller pieces of fiber that would drape around the challenging shapes better. Anyway we are pretty happy that the boat comes out of the mould with deck attached and fin/mastbox + ruddertube in place. I've been thinking about a glass-fiber rudder-tube moulding also, and there's obviously a possibility to add a support under the foredeck for the jib-attachment point, maybe even the mainsheet post tubing also?

Polished PIKANTO hull mould

Shine mould, shine.

After sanding with 1200-grit and a 10-15um particle-size fine paper it is time for polishing. We have two grades of polishing-compound. These pics show the coarse type which is polished with a spinning soft disk on a power-drill.

Pikanto rudder mould

Jari cnc-milled rudder moulds for the Pikanto IOM this weekend. The design is similar to the Sails ETC rudder, but slightly larger and with a NACA 0006 airfoil profile, and a slot for a 4mm rudder stock.

Alioth has been designed by RC Sailing Lab to be manufactured using 3D printing technology.

The project gathered the experience of the lead project designer J.E., who contributed with his extensive experience in the IOM Class and the design team, who worked exhaustively in achieving modern, functional and harmonic shapes.

The purpose is to put on the water a 3D printed IOM hull, easy to assemble at home, and at a low price, capable of winning races at the highest level.

Alioth was launched in December 2020. Thanks to the early Alioth owners and the design team, a new upgrade was launched in February 2022 (Alioth 2022 version): hull shape was slightly modified to achieve better performance in strong winds; flat aft deck with lid-hatch option was implemented; now the hull thickness varies along the length to achieve a stiffer and strongest hull at the less weight possible; new CNC milling appendages molds were made.
