Im tring to find some more bases and fittings like this base . Does it have a particular brand name, and more importantly , can you still get them. happy to by second hand bits
the reason being that I have 1 beginners board, and 2 landboards all with the base plate, but only 1 mast fitting. I want to set up 3 different sails to suit different beginners on the water board, and on the landboards, If I can get another mast fitting then we can have a race!!!!!!

. could also set up the other water board for lighter learners
I dont want to be buying new gear till we have got beyond the wrecking stage on the landboards. money is better spent on daughters lessons. she is graduating to a harness on her next lesson
