Sliding hatch catch

[Ex Machina 313]

Greetings folks

 

I'm in the process of getting my boat up to cat 3 and I'm kind of stumped on how to make the coach roof sliding hatches lockable/unlock able from above and below with washboards in place .

 

Keen to hear everyone's different setups . I'm sure there are some ingenious ideas out there

Lots of boats use a sprung bolt system that has a simple pull string on the inside, and can be locked outside.

I use a door lock. $20 at Bunnings. Key outside, rotating knob inside. Washboards are also attached with lanyards, and a barrel bolt each side on the inside, so they can be individually locked in place if required. Never been an issue, up to cat 1

+1 for the spring loaded barrel bolt thingy. We have ours on the inside to keep it out of the weather, and the pull string to the outside. We have perplex type washboards, so made up another set of ply ones that we set up to use for our storm washboards

Ok thanks for the ideas . I too have Perspex/acrylic washboards so have made ply ones in two parts because companion ways are below the shear line

Hopefully the above link takes you to fosters for the spring loaded catch, cool in all brass but expensive. Haven't found a cheaper version here but plenty on ebay etc.

Try second hand house parts type places, for barrel bolts.

This is what I use: https://www.burnsco.co.nz/shop/rv/hardware/latches-catches-hooks/flush-pull-latch

 

Made specifically for the task. Mounts on washboard and locks hatch into place, can be opened from inside & out. Comes in plastic if weight is important or stainless if not. Never had issues with it and Cat 3 inspector was happy.
