Since this photo I have added a walkway ( not that it should ever have to be used as the trailer is drive on/off ) and finished and fitted my home made boat catch.

This is in capture position.

this is in release position.
Costs me about $8 to make these catches and they work every bit as well as the shop bought catches you pay hundreds of dollars for.
The spring needs replacing about every 3 years but that's about $3 from bunnings.
I have about 6 of these on different boats now and the first one I fitted about 5 years ago is still working perfectly
