Having got to the end of my journey on building IOM's, here is the complete parts list which will get you on the water. All the potential suppliers are listed on the web site under "Useful web sites". You will have to hunt around for the most competitively priced parts. There is only one supplier who will supply you with all you need.
I will update the web site to reflect all the optimisation that has gone on in rigging and fittings. My focus will move onto racing the boats as the season kicks off in early January.
