After many miles under the keels of our MiniCat demo boats we have assembled and disassembled these boats a few times.
For the mast and under trampoline rigging, MiniCat uses sheet-metal shackles and and off brand main-sheet block.
We have found that upgrading to forged shackles, stronger and easier to clasp (I'm looking at you under tramp rigging) really upgrade the security of the boat and even make assembly a bit easier on the hands.
Upgrading the main-sheet block makes a day and night difference in the feel and control of the main sail. The stock block works well, but the cleat on the upgraded Harken block is at a better angle as well as more reliable in high winds.
