Need a foiled rudder ; can I pay someone out there who can do it ?

"Keels generate lift because they flow through the water at a slight angle (boat is getting pushed leeward).  The lift is in the opposite direction of the sails helping to reduce heeling.  A foil keel will do this better than a flat one."

Slode,

Please re-think this statement or clarify your reasoning.

I think I was in another train of thought on the heeling quote, not right at all, lift from a standard center keel increases heeling, sorry. 

Breaking it down to 2 dimensional forces, looking down at the top of the boat, lift from the sails forces the boat in a direction about 90 degrees to the sail).  The keel is then moving through the water at an angle.  This generates lift in the keel and rudder.  These two force vectors work in opposite direction over the centerline of the hull.  The resulting sum of the vectors pushes the boat forward. 

Because the keel lift is a result of the force generated by the sails it is always slightly less so the boat slips sideways to leeward.  This is why a boat with a centerboard/full keel points better than a shoal draft keel.  More keel lift = less slip.  The rudder adds to this so although minimal a foil rudder will improve pointing.

I went ahead, and I ordered the Ida Sailor rudder. While I was moving the boat under motor this past weekend, I noticed the rudder would wobble a lot, so I hope this will fix that problem. Could it be also that the bottom of the boat is fouled with marine growth? I also need to order a new set of bronze bushings to replace the old ones. The prior owner told me he was gonna get the diver to clean the bottom, but it wasn't done as far as I can tell.

Gus,

Plastic milk bottles or water bottles make really good shims. They take up the slack, allow smooth movement and wear for a very long time. Just cut appropriate size pieces and wrap them around the bolts before inserting them. May require some effort but worth it.

Ron, thank you for the tip. I was gonna try to install bronze bushings, but your tip makes much more sense! Thanks!

Buy a foiled rudder from ida sailor. Greatly reduces weather helm.
They are not that expensive.
It made a huge difference with my boat.
It is not a work out any more to steer the boat.

Ida aare the best and ccheaper than hand made by the time all the is said and done..........nies

Late to the party but I agree with those regarding the benefits of the foiled rudder. Before the Compac 23 I had a Flying Scot (also flat blade) and upgraded to the full kickup Ida rudder on the Compac. IME the biggest difference is in turning/tacking. The flat blade causes a lot of drag once you turn in more than a few degrees off center. The foiled is considerably smoother and the boat will pivot/tack better without loosing as much speed. I found it easier to tack quicker without stalling out in the turn.

I found that with my handmade custom wood foiled blade, the boat is faster, points a bit higher, tacks through much easier and is a heckuva lot prettier than any other rudder I've seen. I've had it for over 9 years...still looks like new but to be fair, it took many manhours to build.

Hello!

Thanks for the replies (I didn't mean to hijack the thread). I went with the Ida Sailor rudder. Hopefully it'll be here sometime this week. I usually do everything I can myself (I really like working on boat projects), but I lack the space to do pretty much anything. Next week I have to meet my army unit in Fort Jackson, SC, so I'm picking up the trailer at sailtrailers in Georgia after all that. The yard is going to lift the boat and pressure wash the bottom. Other than getting a head and a few repairs (I bought a 4 inches solar vent, and the hole on the deck is 3 inches, things like that), I should be ready for NCSail Pirates 2018 in September!

Gus,

If you are considering installing a MSD, I would recommend that you look into C-Head composting heads. Cheaper and less mess and smell. My boat came with a MSD installed and I quickly replaced it with a composting head. IMO a typical 23 foot boat can't accommodate a large enough holding tank to make it practical. I would choose a pota potti over the standard MSD.

Just a thought.

Yep, I'd go with a composting head or a Clean Waste toilet with Wag bags and a 3 or 5 gal. storage bucket with a gamma seal lid.  Nothing in between those extremes ever worked well for me.  I took my porta potty out and am using the Clean Waste.  If I cruised for longer periods or had room for a head that was not between the v-berth, I go with composting.

[Gus]

Thanks for the replies. I'll be going with the C-Head. I used to have a porta potty and I hated emptying that thing. We had the wagbags in Iraq, but I think for a couple for a weekend or three days, a composting head will work better (my girlfriend is a little finicky and too princessy to poop in a bag so she told me). If I was alone I'd make my own composting head with a 5 gallon bucket.

Rudder is here. It's awesome to work for a company that left the box outside in the rain (not UPS). I noticed it did have the hole in the back to retrieve it, but not in the front to lowered it. Since its made out of plastic, I'm assuming it floats. What would be the easiest way to lower the rudder? I'm thinking running a line to raise it, and then using the same back hole, run a second line through a pulley to lowered it.

With any luck next week the boat will be in my driveway.

Jus so you know, you can also get Porta pottys that have MSD pump out fittings on them. I just pulled the holding tank and head out of my Sabre and swapped it for a Dometic 975MSD that I plumbed into the existing vent and pump out.

Thanks! I'll keep it in mind.
