Where can Hook and loop (Velcro) be used on a yacht?

[RichardS]

Apparently there are all sorts of hook and loop.

I want to secure my floorboards so they stay in place in the event of a knockdown. Surely there is a type suitable for that? (it wouldn't have to be very strong)

Indeed so .... but 3M Dual Lock is not hook and loop but more like interlocking mushrooms which lock positively in both directions. It is so strong that if you were to use it for something like floor boards you would not want full length strips as you would probably never get it up again. A small length in each corner and in the middle of the long side would be all that would be required.

Although you can get lower profile Dual Lock, it is thicker than hook and loop which can sometimes be a disadvantage.

Thanks for that Richard. I most certainly will follow that up. The Dual Lock only has to hold the weight of a floor board so I wouldn't want to overdo it.

Just had a look on eBay. It is cheap so I'll buy a meter of it tomorrow. ?

ay and it is

Just bought a meter of 25mm. Thanks

Do you use Velcro to secure your computer equipment? Do you think that is the way to go?

No It is probably only made of woven nylon thread or something so it wouldn't stand up to abrasion.

You mention knock downs as something you want to control movement of items if it happens, which suggests rough weather sailing. There are a few stories in flooding situations where the cabin sole has been lifted by the movement of water and caused significant problems trying to move about in the flooded cabin. I would suggest that you need hold down more than just the weight if you have water sloshing about for the following reasons: putting your foot accidentally into the bilge, while water sloshes around could break your ankle, a floating panel acts like a missile as water sloshes around. Both these risks have been mentioned in reports of incidents, so not my invention.

No I had my monitor screwed to a side panel with 2 screws and during a rough passage from Durban to Richards Bay 95 nm the monitor came loose. I refices it to the same panel using 8 screws

I would only use velcro for holding access panels like wiring access panels.

My floor panels are held down with a single countersunk socket screw through a lifting ring with the other end held down with tabs into/under the support frame

I seem to recall that early Spring 25s used Velcro to keep the heads door shut or open. Seemed like a good idea, is it still used?

Would Hook and Loop straps be suitable to secure gas bottles, fuel cans, life ring, dinghy etc on deck?

For gas bottles you might consider the cam lock bands that divers use to secure cylinders.

Sorry! I've got a lot to learn.

Is this what you mean?

Yes. I had a similar arrangement, but the slug (which was round-shouldered) kept either jamming in or pulling right out of the slot in the boom. Several years ago I asked my sailmaker if they could replace the slug with a bigger one which would not pull out, but instead they supplied me with a velcro strap. This is threaded through the clew cringle, round the boom, through the cringle and round the boom again and then stuck to itself. It has worked perfectly ever since.

No, but if the powers that be laid Velcro on the bottom of anchorages we wouldn't need anchors!

Hi Clive I hope the build is going well. I would never trust any velcro with adhesive backing. It is the adhesive that fails. So screw it down and sew it on for keeping cushions in place. Re other things held in place. You can do really well using velcro as a strap. The trick is to sew a loop of steel in the end so that velcro goes through it and back on itself to make a 2x purchase. This then makes the velcro interface load purely in shear so very strong. But easily released by pulling apart in tension. So clamping down fire extinguisher or tools etc. Needs some of the opposite sex sewn onto the back of the tape.
Re the use of double sided velcro. This is wonderful stuff with hook on one side and pile on the other side. I use it to tie down the clew of man sail to boom. Re picture above it replaces the slug on the sail in a track on the boom. it allows the clew to slide along the boom so still use a tackle to adjust it but the velcro holds it down and takes the load of the main sheet into the sail. The strength comes from 3 or more wraps of the velcro through the clew eyelet and around the boom. it is fiddly to fit and remove you need a bit of plastic like a ruler to separate the hook and pile to permit unthreading the velcro. The advantage being the boom is closer to the clew so boom is a little higher. This stuff is sold in haberdashery as cable tidy (Spotlight to you Clive) (Also a good source of velcro by the metre in 20mm or 40mm wide.) ol'will

I hope I never get that much water in the bilges!

I don't want cushions and the contents of lockers strewn all around the cabin in the event of a knockdown. That is why I have over center latches on all locker lids. Now I want something to hold the floor-boards in place.

Thanks
