You can purchase new base direct from Windsport. I have had them ship, (via Royal Mail), to me, here in Canada. The base is £61! About $61USD.

It looks as if a pin can still be inserted. It won’t be captive on one side,but if it holds the foot in place, will still work.
Same as legacy Nacras, the pin just keeps the mast foot from popping off the ball, only needed during the initial portion of the raise. If I trailer sailed, I would definitely get a base with pin.
Dart rudders are $$$++.
They work very well, but are much more complex, parts wise, than the Nacras or my H18.
The good news is they are the same parts as the D15, & there are a few wrecked 18’s around, so buying a used rudder is doable. They use Ackerman angle, so there is a left & right, BUT, grab any one you can, the tiller can be removed from your faulty rudder & swapped out.
I’ve direct sailed against a D18, with a crew that were decent racers, & my N5.7 was easily faster, but that is to be expected with a longer waterline, (19’ vs 18’), taller mast, & more sail area. The Dart jib would make a good hanky, or doily.
That said, when the wind gets up, you are not in survival mode. If my sailing area was consistent light/med wind, I would prefer the Nacra 5.7. If you sail in 20+ often, the Dart is a fantastic boat. I’ve sailed my D15 in 33mph.
For ease of use, no boom, no boards, no tools required, hard to beat that.
