| I replaced my mark 1 RL swing keel with a second hand mark II swing keel. The weight of the original as fitted keel was 94 kgs which was below the class minimum!! The weight of the new keel was 140kgs and the increased width of this keel meant that i had to raise the height of the centre board box about a 100 mm. |
I raced in a good fleet of racing RL 24's at Port Kembla Sailing Club ( money had to be spent). I found the original as fitted keel hopeless as the boat made leeway when going to windward and the boat was also very tippy (The same lee way as a Flying fifteen made). The extra width of the mark II keel and the extra weight solved all the these problems! There was also a design fault in the original cast keel that I am sure Rob Legg knew about! My lips are sealed!
I fitted a filler to go behind the new swing keel and the boat was then competitive with the new the drop keel type RLs. We were on the same rating then and we had to do something to keep up with them. I felt that in over 15 knots of wind I was faster to windward with my 140 kg cast iron job to their expensive 120 kgs of laminar lead job.
The problem with the RL is than when you reduce keel or hull weight the boat does not come up level!! The bow comes up and the back drops down which is bad. All the hot shot RL people are always taking the angle grinders to the blunt end of the boat!!
I hope this information helps you
