We have tried using a 50mm round tube with a 1.5 mm wall thicknes but this has proved a bit fragile, especially with a single triple block hanging from a single point on the boom.
We have a few mossy sailors that run three single blocks off the boom this does spread the load but they are using a dinghy mast section. I will see if I can get some pictures.
