Keel lock for RL24 SK
Does an RL24 SK require a keel lock to meet AYF Cat 5 regulations.
Also how can one be fitted

All Rl 24s (swing or drop) require a positive non friction device which will prevent any movement in the keel in the event of a knockdown or capsize. This is for both category 5 and 6 (AYF special regulations 3.03 page 139 in the current RRS book).

Your mark 1's was built before 1977 and as is bouyant so your keel box does not have to be sealed. I would suggest you fit a filler unit to be slipped into the box after the keel is lowered. The easiest and cheapest way might be to fit a 10 or 15 mm stainless bolt with washers (HIGH UP) through the side of the box.

Having read page 139 (3.03(c)) I can see what you have based you decision on, however I have only your opinion to guide me at this time. What I am seeking is the percentage of fixed ballast on an RL24. I wasn't able to find it in the spec's on this site. It is my understanding that an RL24 is self-righting, even with the keel in the up position.

I have sighted RL24 mark 1s and 2s (swing keel versions) and other trailer yachts lying over on their side with their keels back in the slot. The great thing about the RL 24 is its positive buoyancy which works well when inverted or righted and flooded. You will always have something to hang onto and the buoyancy works well when the flooded boat is being towed back to the ramp.

I strongly advise that all on board wear buoyancy vests in the heavier weather. The secret is to keep a weather eye out for nasty squalls coming and try to drop the main before they hit. Bring her back under jib.

All the Rl 24s that I know of that have capsized, went over from a downwind broach when racing in heavy weather (too much sail up). In one case a heavy person was on the foredeck trying to gybe the kite!!!

Dream On Dump Truck Drop Keel
Howdy all, Just got back to this site and saw chat about Dump truck, my boat (read: proud owner on the Sunshine Coast). I have had Dump Truck since Neralie (Mrs Dream On) said the Status Slipstream (previous boat) was too small on a cruise behind Frazer Is. Women power caused the name change (I'm outnumbered 3 to 1) but at least I can Dream On DumpTruck. That was two Bay to Bays ago. I have been advised by the previous owner & now a current crewman that if the RL24DK drop keel is up more than 300mm the RL24DK is not self righting. I use the existing strop with quick clip over the keel and clipped to the keel case side, the length set prevents the keel from lifting more than the 300mm. In strong wind I have it all the way down and prefer to reef early. Other comment. I believe that apart from ensuring that in the rush of a D/wind run you don't raise the keel too much, the keel hold down really only comes into action and stops the keel travelling when the boat goes well over beyond 180 degrees. In a broach and the boat flattened,the keel is realy jammed pretty chockers in the slot. Its most important job is to stop the keel dropping through top of the case. >>Roll sequence (I have been there in the Status). When the top of the mast touches the water in a broach (>180 deg over) there is lots of windage on our light hulls (the righting moment is also getting less, not more) we usually broach only in strong winds so the boat is blown sideways at a knot or so on its side, the keel well out of the water, with wind pressure on hull bottom, gunnel is under water dragging and rotating the hull and mast down big time. The head of the sail gets under the water surface and it is all over (wedged under more and more water by the down wind drifting)even with the keel in the full down position. The water force on the topside of the sail with drift and the mast leverage will win. At about 270 degrees rolled, cockpit coaming about under and a wave or two inertia and then the keel drops on the case top (SK) or through the upside down cabin roof (DK). Obviously if the keel is full down and locked in the first place it is more likly that the broach would not go so far over and when the boat is on its side the crew can stand on on the keel skiff righting style. We did this in the Status in Bay to Bay storm in which an RL24 rolled and sank. The storm gust front more went fron 10knts up to more than 30knts in seconds. We stood on the keel up came Gone With The Wing and off we went. yahoo
