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

In my pile of bits I have 1 tyronsea set and 2 1/2 of these other types.
good to know the tyronsea stuff is available, that may be the way it goes.
I hate changng the bases around, and am looking forward to racing 2 landboards together

The actual connection looks more like Windrush to me. I don't think you can get these new any more but may be lucky to find one in an old parts bin.
