glue ing davit pads - tips please

My tip is to take it to the professionals and let them sort it out, having been through a similar experience.
 
Fitted snap davits over the winter to my Hardy so therefore had to fit the corresponding pads to my new Seago 270 (PVC). They have been on for 3 months now and dingy pumped up and hanging off the back for probably 6 weeks & all pads A1.

..so this was my technique..

what you need;

2 x cheap 1" paint brushes
1x Thick roll of masking tape
1x Polymarine PVC Boat adhesive (2 pack product). NOT The TUBE!!! that only repairs holes in rubber ducks AFAIK!!
1x decent size dining room and table and understanding wife (room temperature a real advantage, or a heated garage will do!! Don't try this on your foredeck or a pontoon!)

1. Blow dingy up on dining table (about 90% of full/hard inflation)- Mark out area on dingy where you wish to stick pad/pads with HB pencil.

2. Mask up carefully around areas as over-spill of adhesive does dry brown, and you need to ensure adhesive is applied right to the edges of pads and marked out area on dingy so this does come into play later.

3. Clean dingy and pads with Polymarine Solvent or Acetone and leave to dry, then do this again... (I know, you've done it once... but trust me)

4. Mix adhesive 25/1 with curative (says it on the pack), use one of the 2 cheap paint brushes to paint a thin layer of adhesive on the pads and leave for 24hrs. This primes the pads and is only required if sticking onto a PVC dingy.

5. By the way, don't at any point be tempted to get any sand paper and rough up any areas of the dingy or pads...!

6. Prime wipe dingy again (not pads as that has the dry adhesive on now), and allow to dry for 10 minutes, mix adhesive again as per pot instructions

7. Brush on thin coat of adhesive (using your second cheap paint brush, the first one will have had it!) to both surfaces, pads and dingy, leave for 15 minutes.

8. Brush on second thin coat to both surfaces and leave for 5 minutes

9. Now the fun part! while still very tacky bring together with as much pressure as possible.

10. Use the rest of the masking tape to secure pads onto dingy whilst drying takes place. (prior to this point I remove the masked up area of tape as I was slightly unsure if the over-spill of adhesive would bond to the masking tape and never come off.... I suggest you do the same)

11. Leave dingy inflated for minimum of 48hrs, 72 if possible. Do not use pads for 7 days.


Having given a deflating floor of an old Avon rib to "the professionals" for a repair and getting it back and it lasting 2 weeks, I then repaired myself, 2 years later it is still going strong! Jobs like this are easy and certainly not worth paying anyone to do! :)

Good luck!

Spot on reply, I did mine the same way, maybe consider a hair dryer to soften up the vinyl of the transfer, to allow better adhesion between it and tender.

TAKE YOUR TIME AND DO NOT RUSH.

MEASURE TWICE AND FIT ONCE

You will look at this for a long time,(hopefully!!!)

Good luck

Indeed, forgot that bit. As I did this over winter I left the Davit pads on the radiator to get nice and warm and pliable as they were a little misshapen when I got them out the box, certainly helped.


...and AndieMac... having got glue on the carpet in our dining room whilst making a windscreen cover for my last boat & had to do insurance claim to replace the carpet in our entire downstairs (...trouble with open plan house with same carpet thoughout!!) I can honestly say my SWMBO does have her faults... but she is remarkably understanding..:D Just what a good DIYer needs! ;)
 
excellent just what I needed to know to fix my old pads to my new tender.

One more thing though...

Any suggestions or things to look out for when trying to get the pads in the correct position on the tender?

this is what I did... it worked... and this was when the boat was out the water so not that easy!

Inflated tender, lifted it up on bathing platform and got it central to boat transom, as the boat was out the water I then was able to mark on the bathing platform where the snap davits would be best placed and i then fitted them on the bathing platform. Once fitted I then lifted tender up and marked with permanent marker the exact spots when the snap davits hooks touched the tender when tender central to the transom.... then those I ensured were the exact position where the central parts of the snap davit pads were placed. All matched up perfectly when I first fitted dingy to snap davits (must admit I was a little nervous...), so all OK. However plan was to keep on deflating dingy most of the time, however have not bothered... so has sat on the back of the boat ever since. I am just concerned that MDL will now remeasure the boat at some point with tender attached and sting me for another 1ft of dingy!!

The other slight regret is now when I row the dingy (If I can't be bothered to get the outboard out) is that on the downward stroke the oar catches on the snap davit pad making it a little awkward to row.. but not impossible. Not a lot I could do about that as the pads were as low as they could go due to the Seagos rubing strip... but maybe worth considering when you measure up.
 
This is my one of next jobs, new dinghy arrived Avon 280, new pads etc.. onto existing snap davits. Took dinghy down to boat (can't believe the weight of it !) and was going to measure up but ran out of time and really I think I chickened out of it ! Do you think I will be OK gluing the new pads on inside the boat where the temp and humidity is higher, then leaving it all there till I turn up next time, or would you not attempt this at all by the pontoon. The dinghy is a real struggle to get back onto the roof of the car and lash down properly

I am sure if you chose the right weather window you will be fine...but do be aware if its a warm day and there is a little breeze the glue will dry quicker than you might expect so just ensure you adjust timings if necessary. I will admit the weight of this size of dingy is one of the reasons my dingy is now still sitting on its snap davits and not folded up in the cockpit locker.... they are a little heavy!
 
no problem - just a little care

it's fine to do the job outdoors, on the pontoon or wherever - just don't pick a hot sunny day and spend time standing around (drinking cold beer) only to watch the glued area go cloudy as the dew arrives - seconds before you were going to put them together and finish the job!
 
Question about position of pads

Fitted snap davits over the winter to my Hardy so therefore had to fit the corresponding pads to my new Seago 270 (PVC). They have been on for 3 months now and dingy pumped up and hanging off the back for probably 6 weeks & all pads A1.
yone to do! :)

Good luck!

I'm about to fit my newly purchased snap davits (using the toggles as recommended from a previous posting) and glue the pads to the dingy, using Firefly's detailed instructions.

So, checked out the dingy position against the swim platform and the likely position of the pads and where the davits themselves would be best placed, as I am a little nervous about drilling half inch holes in the platform and want to make sure I really do get it right (first time). :o

The davits themselves should be ok but my options for the aftermost pad on the dingy seem to be restricted by slightly raised profiles on the dingy side due to the dingy brand name, the oar retention holder pad and the handle pad. The forward pad position is fine with no raised profiles and so the pad will sit above the centre rubber rubbing strake flush with the dingy side.

The only suitable position for the aft pad results in part of the pad edge (about 3cm*1cm at 3 different points) sitting on one of these raised profiles (about 3mm high). As a proportion of total area covered, the raised edge would be around 5%, but I'm concerned about a weak area developing.

Does anyone have any experience of the pads lying across different levels and if so, do they hold ok or any way of trying to make sure that particular gluing is reinforced? The pads themselves are pretty thick and so making them pliable enough to sit flush over the raised bits looks difficult. I could cut away the overlapping portion of the pad, I suppose, so the pad is flush with the dingy side - does this sound a suitable work around?

The dingy is a Honmarine 2.4m.

many thanks
 
A friend of mine had his pads professionally fitted and they cut away the thinner part on the edge of the pad and then rebated the thicker section so that it sat flat onto the raised section on the dinghy. It looks like they rebated it with a dremmel or similar. They've been on for a few months now and seem fine, it's a neat job too.

One of my pads fouled on one of the pads on the dinghy which the rope handle passes through, so I gently removed it and re-attached it with the pad glue, all's well!

Another thing to be mindful of is existing fittings on the dinghy interfering with the davits when the dinghy is raised and preventing them from closing properly.

I'm currently going through the thought process of fitting the pads to my dingy and have the same issue on both pads where the rope handle is obstructing the fitting of the pads... I was going to cut a semi-circle out the pad but your approach seems a far better solution...

How did you remove the existing rope handle pad please and do they need replacing or just cleaning up and refitting?

many thanks Gary

I heated it up and peeled it off very carefully, a lollypop stick, spoon handle or similar is useful. Having said that I think I was very lucky to get it off and glue it back on again without any problems, not sure I'd have the bottle to do it again! I'd probably opt for cutting the pad around the handle pad. All is still secure though after quite a bit of use and being hung on the davits for quite a while.

And that was why I got the so called professionals to fit my snap davits AND guess what, they made a complete mess of it. The snap davits were not aligned so they had to drill new holes and fill the old, mind you you can't see the old holes, but I was fuming, I felt I should have done the job. A few months later they went out of business (Bare marine).

Hi was just reading your excellent how to on gluing davit pads and have a few questions .
Do you think it would be ok to use isopropyl as a cleaner instead of acetone ?
Have purchased the Polymarine pvc 2 part adhesive, on reading the instructions i noticed they recommended priming the davit pads as they are rubber with hypalon adhesive for a successful bond and goes on to state.
PVC Adhesive does not stick to Rubber
PVC Adhesive Does stick to Hypalon Adhesive
Hypalon Adhesive DOES stick to rubber
Unfortunately the kit does not contain the hypalon adhesive 2990 to use as a primer on the pads.
Would appreciate your thoughts and any advice on this .
