Its also good to have a few blocks, especially the ones where the side snaps open and shut, so you can rig up a replacement block and tackle arrangement if the vang breaks. The newer ones are much better. Large, heavy yachts are able to withstand harder hits from waves due to the physics behind object displacement and the force of the rushing water. Therefore, your boat will need to be durably constructed to withstand this force. (You must log in or sign up to reply here.
