Simple Rear Hatch locks

[properchopper]

When I rigged my Insane 34" Mono, I pinned the front of the hatch. After a while I thought I'd do the rear. I bought a pair of small spring loaded locks, but to keep water from coming in these was not easily done. With a few parts laying around, [ screw anchor, 10-24 bolt, screw protector, cut-in-half grommet for seal] I made these : Simple, cheap, easy to use

I use a very simular system as that as well,But where your insert nuts are i have a bolt coming up from inside the lip with a nut screwed on to hold the vertical bolt. I then cut a piece of silicon tube of required length that is a tight fit on the bolt & slid it on. The vertical bolt passes through the hole in the hatch as yours does with a knurled nut tightened down on the top of the hatch. when its tightened down it squashes the hatch against the silicon tube. Its 100% water proof. Martin

Very cool, thanks.

Martin, I thought of a variation of that : having the screw anchor protrude through the hatch with a knob/bolt holding it down. There's more than one way to skin a cat (er mono)

I find that on the small boats (15") im restricted on size & area that i have on everything so a 3mm nut & bolt coming up through the lip is a bit easier getting it in in restricted areas due to the very small sizes. Martin.

I think I'm going to do this on my boats. Inexpensive too!!

I also find when you put tape around the hatch on a curved front hatch that 1" or even .75" wide tape dosnt go round & sit flat very well. If you use 1/2" or 5/8" wide tape it stretches nice around curved hatches sitting flat. If i cant find the width tape i want i simply cut a complete roll to the width i want. Martin.

I'm getting sick of taping hatches actually...

[martin]

Dont know about you guys but i like to have positive fixings front & rear on hatches & not just tape. It amazes me when some one has a high speed crash & wonders why the hatch comes of & says well i had the hatch taped down.

nice tip tony thanks

Just put something similar on my pursuit

[Superdave]

Jabbo, how did you secure the screw in place? I want to do this to my Pursuit as well!

The more I think about it, the more I like your way of doing it. The squished silicone seal makes a lot of sense.Either way, those bolt thingies or knurled nuts have a habit of hiding or roling into the unknown. My bolts are stainless, otherwise I'd just put a magnet under the hatch to trap them on top once dis-attached. I'll try the magnet thing next build when I use your idea if I use ferrous nuts.

I drilled and taped a piece of 1/8 thick 3/4 wide aluminum loctite the screws in that then siliconed the aluminum bar to the inside of the boat.

Tony to help me from losing small parts such as hatch screws I attached small tins to my boat stands it works great.
