I am interested to known what methods are used to ensure the keel does not retract on captize for the RL24.

keel lockdown
Robert, our RL24 has a bolt that stops the swing keel from retracting. With the keel in the down position the SS bolt and nut is positioned just above the top and towards the rear end of the keel.

Keel Lockdown
Robert, In my opinion having a swing keel locked down defeats the purpose of having a swing keel. The obvious thing is not to get knocked down in the first place. Consider that in case of a knockdown the weight of the keel in a sideways position would probably reduce the ease at which the keel would slip back into the houseing anyway. Never having been knocked down I can't say for sure though. Keep it straight!!!

kock down
When you have experienced a knock down, you will change your mind. You will NOT right the boat without the keel in the normal down position (or part there of)if you are knocked down. The keel will slip up into the case and you then have no canterlever weight or opportunity to right the boat. Trust me, I have experienced this unpleasant experience. I agree that avoiding a knock down is the way to go, however there is always the unknown when it comes to nature and the weather.

Keel locked down
I agree with Alex. We also have never been knocked down in spite of pushing it a number of times. The RL 24 is very forgiving. Other considerations are you can readily tune helm balance on all points of sail by varying keel position, speed and balance is much improved on a run and a reach by partially raising the keel, particualrly under spinnaker. We are told the swing keel version will self right with the keel fully retracted and it is some comfort sailing in shallow waters that the keel can kick up without damage.

Keel bolted down or not.
We sail our boat without the swing keel bolted in the perminantly down position...and is of a great help in shallow waters. However...If I were in deep water,with a chance (however slim) of being knocked down, I would have the keel in the perminant down position...reasons being)) 1-Imagine if the boat goes completely over upsidedown and the keel comes slamming down into the casing? I'm sure my keel-casing won't be intact...in the perminant position this won't happen. 2-If the boat was knocked onto it's side; why would you want to bring the keel in? The boat has a better chance of righting itself with the keel down (as the leadweight further away from the pivoting point).

Keel Lockdown
I sugest that you all read the current copy of the AYF Racing Rules of Sailing. All boats with movable keels racing up to Category 6 must have a non friction device to prevent the keel moving in a knockdown (AYF Special Regulation 3.03 (c)).

I have a device that I fit into the rear of the box when the keel is down. The rules also call for the box to be sealed so the top of my box has a gasketed quick release cover.

The early rl 24's with 100 kg lightweight keels were a wee bit tippy. This along with the smaller early rudder blades caused a few control problems when racing down wind in a breeze. I have seen a mark 2 with a 130 kg keel stuck on it side with the keel retracted.

Whilst we have discussed the merits of getting and not getting knocked down, we have not addressed Roberts main question and that is methods of locking down the keel. I for one would be interested in knowing how to set up a locking device which can be quickly put on and taken off allowing me to sail happily with no lock but having the ability to lock the keel if things turn bad.

You are quite right Alex,

I recommend that you use a filler to prevent the keel from falling back into the box when you are knocked down. It is a very positive and watertight method as against the bolt system. It means you will have to change the top end rear cover of your centre board box.

In the other boats where they use the bolt through the box system you will find that no one bothers to fit the bolt once the keel is lowered even though it is required by the racing rules If made using a flap the filler can also improve performance of the boat by reducing turbulance in the rear area of the box. In Victoria you will receive a very heavy handicap penalty when CBH racing your RL 24 if you fit a flap!!

I will photograph my filler and the quick release top cover system fitted to my boat and if possible put them in this forum site.

Would really appreciate diagram or picky and explanation of construction. Thanks

Thank you all for your responses to my question. I have located the lock down pin and appreciate the discussion on when or if to use it. Safety rather than speed is my immediate concern as I usually have my five year old boy on board and dread the thought of a knockdown. I recently spent 4 weeks at Tin Can Inlet in very shallow waters. At times the winds came in very quickly and became too strong for me. My concern was 1. running aground in strong winds with the keel locked down and getting stuck with sails up. 2. running aground without the keel locked down and getting knocked down immediately. An onlooker who had seen me do the latter of two suggested that a rope or wire could be attached to the front of the keel run up through the keel housing and cleated near the keel winch giving a quick release system. Has anyone done or heard of this option.? Would it work?. Any thoughts.? Robert.

Knock down

I do not know anything about your sailing area but you should carry a simple risk assessment to your boat and the way you use it. I think all RL 24s were built with foam bouyancy so not like other trailer yachts your boat should not sink when flooded. Even when floating on her side no water will come into the cabin. All young children on the boat should wear PFD1 type life jackets when sailing. Always sail when other boats are about and if you need assistance let a flare off.

Southerly busters can be seen coming so keep a weather eye open at all times for one and if you see it coming drop the mainsail and stow it. I have sailed and tacked to windward in 35 knots of wind in smooth water with just the jib up. I was quite surprised and I reckon that no other trailer yacht would be able to do that. I have a skiff rig on my RL which helped. Remember, never leave the boat to swim to the shore if its floating.
