I need to replace the mount for dual foot blocks, that turn the staysail (173 ft squared) and genoa (543 ft squared) sheets to the winches. The sheets are 14mm, rig masthead, LOA 41’. Currently the foundation is a teak block about 200mm long, 150mm high sides around 45 degrees angle to the deck.
Currently planning on replacing the teak block with 5mm thick stainless, with a base of 200x150mm and a single side of 200x150mm set at 45 degrees to the base. The dual foot block will be mounted on the 45 degree plate.
Do you think this will be strong enough not to distort under load? I know that adding a 3rd side, or just ends, will make the shape stronger, but I need good access inside for the foundation bolts nuts. The edges will all be rounded and corners will have a good radius. The plan is for a full penetration weld to join both plates, or to heat a plate and bend it.
Any ideas on strength would be appreciated e.g. should I go up a size in plate. My welder will make what I ask for.
Thanks, Runagroundhard.
