Lifting dinghy on board using a spare halyard.

[Poignard]

There will be no stress using a halyard.

It is a done deal; I had already decided that I will use a halyard, (as did Eric Hiscock).

There was never any question of my not doing so.

I may also use a spinnaker pole with the halyard to make it even easier.

I simply wanted to know the pros and cons of using a 2-legged or a 3-legged bridle.

That's all.

I can see the spinaker pole gives a lifting boom, and might have to investigate how to rig it above the cockpit

Isn't there a boom above the cockpit already? Why not use that - halyard through a snatch block towards the end of the boom?

2 leg bridle the dinghy will try its' best to turn upside down.

But if I fitted the padeye high up on the transom, the top of which is ca 50mm above the top of the tubes, the centre of gravity would, I think, be slightly below an imaginary line between the padeye and the painter ring. The plywood bottom boards would be in place and they weigh 10lbs.

If that is so, the dinghy would not capsize but would be easy to tilt, if required.

You could also fit 3 pad eyes and have both options.

You will be surprised I think. I have a dinghy in davits and have tried a two point lift with no success Do not assume that the the tubes, floor, anything is symmetrically weighted. I now lift with a three point system and it can still sometimes come up screwiff! Good luck.

The topping lift would certainly need replacing as not intended for any load other than weight of sail and boom. Depending on arrangements, on a small yacht the boom is not necessarilly high enough to life dinghy on straps clear of the guard rails.

We discussed use of boom for hoisting at the club when practising Man over Board drill. I however will concede that our dinghy much lighter than hefty lifeguard playing at being our casualty. Handy Billy bought for MOB and best use on our craft is to set it from spinaker halliard with join raised above head height

 

[Poignard]

I suppose I could top up the boom to give the necessary clearance.

Now everyone's shot one another to bits I'll pipe up.

I'd use a three legged bridle for the simple reason that two legs assumes the dinghy will hang horizontally. It won't. Even a pint of water in the bottom will tip it to one side or the other like the Herald of Free Enterpise and it will always have a tilt. Add an unhelpful breeze and it'll be broadside on to the wind making life as hard as possible. With three legs it'll always sit obediently flat.

A very good point. Definitely is. Of course the dinghy being flat-bottomed water will slop to one side or the other. I hadn't considered that.

Thank you.

Which is why I pull mine up bow first with the drain plug open. Up enough to pull onto the guard wire then ease the halyard as i pull it onto the coachroof. I don't have an outboard motor so no worry about hull damage.

A tilt could be included in the design by making the bow bridle a few inches shorter than the two at the transom. With the bung out it could be lifted clear of the water and left to drain before proceeding.

I haul a hard dinghy on deck using a 4 point bridle and a rib using a 3 point. The advantage of the 4 point is that once the dinghy is on the trestles, it can be easily rolled by lifting on the port or starboard bridle attachments only. The rib is light so it rolled using two of the three bridle points. The outboards come off separate to the dinghies.
