I make my own fiberglass battens for the underside. I differ from what they show by grinding off all the gelcoat on the removable part. After the part is glued in the entire part and it's attachemnt area is covered in one piece of fiberglass. You could grind to the surrounding area to the...

Why the Shoreline method works for me is often the tub has a crack down the middle. I can fiberglass the bottom of the tub before moving on. The whole idea was to reuse the broken piece by encapsulating it in fiberglass top and bottom. Normally you would never reuse the broken part but...

Answer is still the Shoreline method.

If you mess around with used Sunfish Sunfish the damage shown is very common. Get familiar with the Shoreline method of repair because you'll be doing it many times. The good part is you can add extra layers to the back of the damaged section you removed so that it's pretty much unbreakable...

I have a old style rudder. I'm thinking the shipping cost is going to be a lot more than what it takes to make a new one as I'll only send the whole unit with bracket and tiller handle. It's such a cool wall hanger I don't have the heart to break it up. What Alan said! If it's split it's...

Put it on a waterlogged Sunfish, pull it 20 yards up a grass incline and report back. I think someone sporting a pirate hook on one arm would like it.

Thingverse has some Sunfish parts including a rudder blade. The mast cap looks like a improvement over the stock unit. We just need someone to print these and try them out. I'd be interested to see a sunfish with as many printed parts a possible, see if they all hold up.

Rudder bracket could use some additional webbing as it has a cracking problem in the corners. Some gussets in the corners might help. If you could print it in nylon it would be pretty indestructible.

Subject comes up from time to time but that's as far as it goes. Need someone who's both a 3D printer enthusiast and Sunfish enthusiast. Drain plug and Rudder bracket come to mind. It would only take one person and the 3D designs would be floating around on the internet for eternity.

Probably a Wet Suit but then you need to determine the thickness of the Wet Suit depending on how cold you are going and knowing when a Wet Suit can no longer help you. I stay away from cold water as it can impact my health if I get it wrong.

Someone truly knew what they were doing but why? That's a fantastic amount of labor done professionally. Someones college thesis in hydrodynamic engineering or a bet made after too many beers?

Have you considered printing with nylon? It has almost double the tensile strength of ABS. I'm pretty sure it would make cracking almost impossible.

Been looking for someone to try printing the Depsersia drain plugs. The trick would be to have enough printing resolution to do the threads. The overpriced plastic rudder cheeks they sell could be engineered better. The reinforcement webbing allows cracks in the corners. Thicker webbing, a...

That is a common crack, what does the keel under the tub look like? If you are lucky/unlucky enough to have cracked or damaged keel it's easy to enough to fiberglass the bottom of the tub when you cut out the damaged section of the keel. I've not tried it but if you can put a inspection port...

You can use a standard pipe plug found at the hardware store. A Garbard Plug also works. Rubber stopper/ cork or no plug at all is also good. Outside threads are also standard and the retaining ring is a standard sink drain retainer.
