    The Evolution of the Morf Block: Product Update

    Morf Block Deck Block


    Morf Block emerged as an original idea.


    Founded and forged by G Yacht Design, the concept materialised as a DIY block. The kit - comprised of the block cheeks, plain bearing and Dyneema® attachment - allowed purchasers to build their own blocks, using the lash thimble of their preference. Appealing to riggers, amongst others, the kit was sold in a number of sizes, with each size suitable for several brands of lash thimble. However, now, things have evolved.
