I agree wuth Haydn, the dinghy can look a bit odd but I have used both and prefer snap davits.
Mine is a 2.7m tender and the snap davits save me about one metre on my LOA for mooring charges. As well as this they are incredibly easy to use, I simply drive up to the bathing platform and the tender latches into the davits.
The down sides are
1. You cannot store the outboard on the tender
2. You need to check the distance between bathing platform and water
Snap davits work well, especially with integral bathing platforms.
The relationship between the dinghy/fastenings and the bathing platform is crucial if they are to work well.
One thing to watch - I tend to bring the dinghy alongside the wrong way round so to speak - the metal clips can scratch your stainless rubbing strake or grp if its rough, so I clip the dinghys grab line to the davits and hey presto instant mooring.
Turn it round, hoist it up and make it fast when you're ready to go.
Snap Davits are quick and very easy to use but they tend to make you swear a lot more. Watch your toes!!
Difficult to lock tender onto but have had a piece welded onto my weaver davits so can put a padlock through.
I have replaced conventional davits with snap davits on my last two boats. The reasons as stated below are reduces length by about 1 metre which helps for both fees and manoeverability. The engine does have to be removed but I have had brackets fabricated to store the engine in the gap on the bathing platform behind the dinghy. Main disadvantage is the restricted ability to use the bathing platform when the dinghy is stowed.
IMHO I would not use conventional davits unless the dinghy was of such a size/weight to make snap davits unusable.
Bloody hell, I am having to agree with HLB again. Snap davits are OK for small dinghies but who wants to be bothered unslinging the engine every time + there is always the risk you drop the engine at the critical moment, especially in any sea when boat and dinghy are rising and falling at unsynchronised moments. Naturally all sensible boaters would have it attached by a bit of rope for just such an emergency but it doesnt go very well immediately after a dowsing.
If you have a dinghy of any size with a bigger engine, it is just not feasible and davits are so much easier. Also, on flybridge boats, I think they look better, perhaps less so on sports cruisers.
I had snap davits on my last boat and I'd never use them again because they're a pain in the bum
1. You cant walk on the bathing platform with the tender in place
2. You have to remove the engine
3. They're difficult to lock on when the water's choppy
4. They scratch your gel coat
5. The back of your boat looks naff
as a relativey small boat (not a nice flybridge - yet) the issue is more between roll up and stow or s/davits than davits / sdavits. Equally the outboard issues less important (a problem either way!).
You seem to confirm that they do what they say well enough and the old plastic will get an airing......
The mention of a padlock addition to the Weaver is interesting because when I asked wether this was standard I was told it wasn't because even if you lock it to the platfom mounted base either the metal bit can be removed from the dingy quite easily or the knobbly rubber bit can be cut through where the metal attaches to the dingy. Comments?
Thanks again (and sry to be a further contribution to Nick and Haydn's forthcoming engagement.............)
There are 2 metal rings which are attached to rubber patches stuck onto the fabric of the dinghy and I suppose somebody with a craft knife could cut them away. However any form of security might be enough of a deterrent to make the dirtbags go to the boat next door
The only problem I have found with every type of lock I've ever used is that it only takes a few weeks before they corrode so they need regular applications of WD40 or similar
The metal bit you snap onto our boat davits can only be removed if they are prepared to spend a lot of time under the bathing platform trying to undo nuts and bolts to steal it (makes the thief look rather obvious)The knobbly bits are strengthened with metal so again very hard to cut, so it just makes life that much harder for the opportunist thief. My last tender was stolen because it only takes seconds to untie or cut a rope.
They would have to really want this one to get it and if you go over the top on security what damage will they do to your boat?
Should have made it clearer, the welded bits on the davits let me lock the sliding handle shut so the tender cannot be lifted off or turned over to get at the nuts and bolts without getting into the water and even then it is difficult.
Agree with most everything said so far on this - the metal bits on the tender can do horrible damage to gelcoat. As for unmounting the engine, take a look at the new "Weaver Leaver" system. It's a swinging transom plate that allows the engine to be left attached. Also, use the standoff arms that Weaver do - they keep the tender clear and leave much of the platform free.
