If I build a camp cruiser cat and put a Hobie 18 rig on it how heave can I go and still get around 75% of wind speed. 10 knots boat speed reaching in 15...

Does anyone know the percentage weight saving of a foam cored daggerboard over a cedar cored board? Apologies if I missed this when searching the archives. ...
WR Cedar comes in at 380 kg/cu.meter (varies from approx 21 to 28 lbs/cuft from memory) Compare that to whatever foam density you'd select (typically 5 to 10...
Designer White once said that the difference between cedar strip construction with glass and foam and glass was about a savings of 20% weight for the foam. ...

I am showing my ignorance here, but what would the effects be if I decided to put transom hung rudders (=less complicated to build) on my 9m cat instead of...
Yes,,,,it is in tight supply,,,,but I could probably spare a few rolls,,,,. I have an 9.2 osy carbon uni (8.8 osy of carbon,,,and .4osy of black fiberglass...
Hi Lincoln I've been worrying on the same issue - moving rudders aft - for my 24' cat. But the experience of TomLamers (which I read on the SW24 forum) was...
Hi Tom, It is a Woods Skua. If I can, I hope to launch later this year. Thanks for the advice, now I just need to let all this info fester for a while before I...
Here's the current direction I'm looking in a quest for replacing the stock transom hung rudders on my SW24 The sketch (Album: Simple Kickup Rudder) represents...
Hi Tom, Looks like a good design to me. The thing I would worry about is what will happen when it is part way kicked up and there is side force on it from the...
... My boat is a Woods Meander. It uses exactly what you sketched with the following difference: my transom is not immersed, so the little wedge that fills...
Tom, That looks to be roughly the same design Richard has for the Skua (and I think some of his other designs as well). It is pretty slick, although the weak...
Hi Arjan, There was no sealant on mine when I removed it. Didn't leak either. I would consult the manufacturer though. ... [Non-text portions of this message...

Within reason, I don't think weight matters much. Obviously a 5 tonner might be a bit much :) A heavier multi, or any other boat for that matter, won't...
Will likely need to be made a bit deeper, surface piercing foils (which a stern hung rudder is) ventilate to some percentage, reducing their effective area. ...
My Buccaneer 33' plans shows the original rudder under the hull. Then drew an optional transom hung which is how my boat is built, With no apparant change...

If you incline the rudder blade forward at the bottom, so the bottom tip is in front of the pintle ( ie a balanced rudder) there is much less inclination to...
