Secure hold downs for bunk boards and nav table etc

Postby edelweiss » Tue Jan 10, 2012 1:52 am

Looking for ideas for hold downs for the numerous boards that go under bunks, nav table and "chilly bin". I happened across a interesting you tube video from Great Britain that demonstrated a video of a staged ( they used a strap and a crane ) roll over showing everything flying out of the various storage compartments. Link to the video and others by googling yachting monthly crash test.
There is suppose to be some special category for people who can learn from others and I am trying to qualify as one of those having spent plenty of time in the other category. So..... secure hold downs for now. Pictures really appreciated if anyone has done this.

This yachting monthly series is too cool to miss. There are several videos in a series including the most recent which is an explosion. ( Nasty old propane stuff).

Sorry, no pic today, but this is easy to envision:

Get some hinges with easily removable pins. Install then flat on both ends of the board. Stainless is nice to have. I use these for my built in battery boxes. Hope they are enough. I also hope I never find out.

This isn't the perfect solution for everything you mention, but it is good for many. My companionway steps / engine cover had simple barrel bolts, and these weren't even good enough for a seaway. I used heavy hatch dogs to hold this in place.

Peter,
I fabricated a new battery box to hold 2 Trojan sized batteries. On our 38HC they are located under the aft bunks on port and stbd. I would enjoy seeing your battery hold down ideas. I was also curious about holding down the bunk boards.

Hi! I am not good at all to post photos here. Pls, use my mail, I will answer asap. As you see, I have a Christina, she have a tunnel under the cockpit wher the gen set are located. Thre I have constructed first one box system fot the four batterys, then another flor for the gen set. The genset can be slided out for service. All floors, layers are very strong secured to the hull. I think we are able to take a roleover with the items stil at place. I hope never come in that situation, but its OK anyway. I have not thinked at the flooreboards, yeat.
Will come!

Be sure to do step 6. This is where most people have a problem. It's easy, but it isn't obvious.

Good Luck! And send me an email if you do have a problem.
