On the flip side of that I much prefer a cassette rudder to a swinging rudder. I can get it up 1/3 to 1/2 on the way in and still maintain a light rudder load and much better control.

I should've been clearer- I was referring to multiple rig hulls

conversely that claim can be dismissed in terms of boat handling and set up knowledge and experience deficits...

Here is a good video showing low speed boat handling of the rudder on the Laser Radial and the RS Aero by Olympian Penny Clark. Edited by Peter Barton - 22 Mar 16 at 9:24pm |

Yes but .... Reminds me of a story involving Peaky ... when he had a crew and an Icon. We encouraged him to enter the Sheppey Race with said Icon (which had a cassette rudder- it was allowed and was his preferred weapon) Anyway we expressed concern about the possibility of 'hitting the hard stuff' which as many know is just possible at Sheppey ( ). Anyway Toby insisted he would/could so very easily 'raise the foil' maybe 50% or whatever in 'the shallow areas' .. and rejected our offer of a loaned pivotting one). Those who know Sheppey will already be shoulting out loud that the water is pretty murky and it is mostly impossible to see more than 3" through the stuff let alone see all the potential shallows .... Anyway about 5 miles into the race the inevitable happened - resulting in the transom fittings departing from the back of the boat complete with the casette stock and blade. (Well Peaky was surprised anyway).... Credit to him he hung onto the extension and recovered the bits .. and then sailed back 5 miles upwind without a rudder at all.... The moral of the story - Life (and the hard stuff) often gets you when you are not expecting it. Nothing wrong with cassette arrangements btw if you never touch the hard stuff - but they are not always the most practical or best thing either.... if you want the 'best' then there are many who wil argue that a fixed one is superior to anything - it is but for everything, all of the time and for everybody ? Mass produced boats that are going to sell widely will get used at a very wide range of locations - the 'best' generic default solution as on the Laser, plus now Aero and many more SMOD boats therefore has to be a pivoting rudder surely ?

Or a combination of both- where the stock pivots - but I guess that adds (unnecessary) cost

Perhaps you should find out the experience, knowledge and set up ability of the person you speak about prior to making a comment like that. Having owned several Lasers over the years from an old beater boat as my first right up to a brand new one they all had a heavy rudder to a greater or lesser degree. Having borrowed other Lasers at times (we liked to boat swap just for comparison purposes) they also all had a heavy rudders. Then you jump in to something like a Phantom, Blaze, Fireball, Icon, Scorpion, D-Zero, Byte (which has a very similar rudder to a Laser), Mirror, Vision, 2000, Vago, so so on... and they all have a much lower rudder load and a much better feel. Go figure

That has disadvantages as well as advantages. Very easy to drag a lightly loaded rudder sideways through the water, creating just as much drag as if it were a heavily loaded one. The Laser shouts at you to tell you you are sailing badly, whereas other boats may keep it a secret.

Laser shouts at you when you are sailing well a lot tbh. Its a fair point that the crap rudder does punish poor sailing especially bear aways more than a good one.
It is one of many elements that reduce its popularity with beginners tho! |

Yep, it can't be said too often that every design is a compromise. I'm not a fan of putting beginners in crap boats as too often seemed to happen especially in the old days, but its also not good to put them in boats which make it easy to develop bad habits if there's no other means of helping them overcome them.
