Mac 25 Rudder-Tiller- Thread starter David M

- Ask A Macgregor Owner
I am a new owner of a 1976 Mac Venture 25 and a novice in this size sailboat. I am in the process of rebuilding this project and have some questions about the rudder-tiller and was wondering if anyone can help with information about this subject. I am also a new member on this forum. The rudder-tiller looks like it is either teak or mahogony. The rudder (segment that sticks in the water is all sanded down, and it has age-drying cracks) and I was thinking about fixing this portion. What would be the best way to rebuild this segment. The cracks could be filled with a marine epoxy or wood filler, then what would the next steps be? Finish the wood with marine varnish, then put fiberglass matting over, then fiberglass resin, then antifouling paint? The next item is the wood portion of the rudder system that goes veritcal connecting the lower rudder to the tiller. That section is junk and I need to replace it. I do not know if this is teak or mahogony. Is there a good place to buy this wood. The size piece need is about 38" long x 11" wide x 1-1/4" thick. I thought of contacting a local cabinet shop to find the wood. The tiller segment just needs sanding and refinishing. Does anyone know of a good marine product that is best suited for the finish on teak or mahogony? Next question: The entire rudder system was taken apart. I also am looking for a diagram or drawings to be able to put the rudder system back together including the rigging of it. In addition, is there a diagram or any drawings available out there to be able to get the dimensions of the vertical wood rudder piece to make a new one as mine is damaged. I know this is alot of information needed and if anyone could help, suggest or point me in the right direction I would really appreciate it. Again, I am a novice at this so I could really use advice on this. Thank you. David  Rather than spending time and money repairing the old rudder, apply that expense to an Ida rudder. It suppose to improve performance and will increase the balue of your boat.  search is your friend... 1st question, is the centerboard working properly. if you have a problem with the iron keel, or its operation, its a major project and should be checked before investing too much time or money. once that's A OK, improving the rudder is the #1 best place to improve the handling of the boat. the ruddercraft rudder assembly while not cheap is worth it IMHO. and fwiw, the rudder on the 87-89 26D is the same. no go read some old threads... David: How much access do you have to junk boat parts or old Mac parts? If you're lucky, the better combination to find would be the metal rudder assembly for the upper portion (used on 1981+ Macs, I believe) and the Ida rudder caguy mentioned. Otherwise, it sounds like you've got the two piece system where the two halves are joined by two metal plates, and one section has a curved notch in it to accomodate the pivoting motion of the lower half. The assembly I have on my '81 Mac has the two halves, but they certainly aren't teak or mahogany. They're about the size you suggested, encased in fiberglass with a gelcoat finish. I've attached a few pics. Is this what you are talking about? Finally, will this boat be in the water all the time, or for significant periods over a season? If it is going to be trailered most of the time, I wonder how necessary the antifouling paint is. Attachments MrMikey64 said: David: How much access do you have to junk boat parts or old Mac parts?

Click to expand If it's been a couple of years since it's last application, you're probably going to need to do it again fairly soon. MrBill makesa very good point about checking the swing keel as soon as you can, especially around the pivot and lock bolt holes and the bolts themselves. Many a keel has been lost due to neglect in these areas - and it would be a shame to put a lot of work into the rest of the boat only to have the keel fall off, pretty much making the boat useless and worthless. As for the rudder midsection, that isn't something you'll find through Ida rudder - they will only have the actual blades that make up the lowest portion. If you do a search both in the forum and online as to how to build a rudder, you can see a few examples of what people have done in your situation. It just might be worth it to rework what you have. As to the one in my pics, the mating plates were so badly pitted and damaged that I had to find replacement aluminum plate, which should do the job nicely. Other than that, I filled in the damaged areas with epoxy, and will apply a gelcoat finish to the outside. Congrats on the new (to you) Venture, and enjoy the experience! David M said: (Your 1st question, is the centerboard working properly. if you have a problem with the iron keel, or its operation.) This is a very good question to verify . What would be the best way to check this out? It is currently on a trailer. Should it be brought to a marina and have them lift it up off the trailer to see how this is working (or not)? What would you suggest as a process to do see how this is working? Just use the crank to lower once the boat is lifted up? Is there any locking pin that I need to be aware of? I would appreciate any insight. Thank you, David Click to expand David M said: Is there any locking pin that I need to be aware of? Click to expand in fla, I'd splash the boat and put a masks on to check the keel. but in WI, its safer to lift the boat off the trl, and remove the keel, epoxy seal it, and install new bearings. if you have a keel problem it could make the boat worthless. better be sure before going in too deep sumner's website had a very good documentation on lifting the boat off the trl. - but you have a ~600# keel... be careful. http://purplesagetradingpost.com/sumner/macgregor/macgregor-index.html if you have that 2 piece rudder sytem, I'd junk that and get a new blade or entire assembly. you can build one if you have more time than $. its all here in the archives. I have a Venture 2-24 that I rebuilt the last two years I did a bunch of research and if you are a good project/builder kind of person you can rebuild the rudder assembly. I'm not too good at projects so I bought the Ida replacement It is very good but cost $960.oo with everything. Lost HorizonI got the same rudder The rudder on my '81 looks the same as yours. I ground out and filled cracks and covered bare wood spots with fiberglass, and just bought new 1/4 inch aluminum plates for $26 to hold the two haves together. I can send you measurements if you like. $900 to Ida would be nice if I could afford it but that's twice what the boat is worth! Someone should make cheap fiberglass rudders for us and charge a couple hundred instead of six, and they wouldn't break like the plastic IDA rudders either. I would consider making the rudder castle out of channel aluminum and aluminum plates-and be done with it if mine was shot.  ChockFullOnuts222As long as the rudder blade (lower part) isn't so badly damaged that it's falling apart or can be broken by hand like driftwood, I would say fix it. Wrap the wood in fiberglass, and you should never have to worry about it again. Just make sure you don't forget to line the holes with resin, too. An epoxy resin, rather than a polyester resin (like Bondo products) would last a lot longer and offer a lot more quality. Fixing and refinishing your existing rudder parts will be a lot cheaper than buying a brand new set of parts---especially that Ida rudder. I can understand everyone raving about the Ida-rudder's performance; but for $900, I think I'd rather just either fix what I had or try building new parts from scratch. - This site uses cookies to help personalise content, tailor your experience and to keep you logged in if you register.
