Whether now or later, consider the Marelon OEM Series 93 thru hull with valve, which includes the thru hull. It has a built in flange (3" I believe. They call it a king nut) They are used by many boat builders.
They are easy to install, come with mushroom head thru hulls or flush thru hulls. I put mine on 3 1/2" G10 1/8" thick backing plates for extra strength and to have a smooth surface for the king nut. Backing plates are easy to cut out of a sheet of G10 using a hole saw. Then drill the correct size hole for the thru hull in the backing plate and epoxy it into place.

A lot of traditionalist want bronze but there are a lot of boats, used and new with Marelon. I haven't heard anything bad about the Marelon OEM Series 93 thru hull.

As I also have a 30' boat, I'll mention that all of my thru hulls, sink drains and water intakes are 3/4".

I’ll definitely keep that in mind. This guy didn’t even check my thru-hulls—he just said, “they’ll last longer than we will,” and painted right over them without inspecting anything. I get the feeling he just wants to get paid and move on.

Next time, I’ll try to find a more professional boatyard.

What a learning experience.

Paint looks good. Just wondering about the two pictures here. What is the purpose of painting the rudder? Just curious about the process.

In the first picture it looks like the bottom was painted while the boat was in slings, and the area under the slings not touched up. No big deal; you might just want to make sure to sand that section a little extra before repainting the bottom when you do.

In the second picture you’ll want to replace the anode before relaunching. That’s fast and easy. The existing one looks a bit deteriorated, and it looks like it has some bottom paint on it which will reduce its effectiveness. Be sure to sand the prop shaft a bit to get good connectivity before installing the new one.

The rudder needs paint like everything else on the bottom to prevent fouling growth. If barnacles or excessive slime are allowed to grow anywhere on the bottom the boat will be slowed. If they grow on the rudder steerage will also be a bit compromised.

I will try to get him to sign a 6 month guarantee on the work.
Good luck with that. Be careful about taking an adversarial approach. :banghead:
A softer approach would be ask if he guarantees his work, and if so ask for his guaranty in writing, or just ask for this in an email or text and his reply in writing is sufficient. You need to work with people who provide services, not against them. Keep it friendly and agreeable whenever possible. If you seem like a troublemaker they will avoid you and will be “too busy” or they’ll give you their worst (“I don’t want your business”) price.

Okay, that's a great idea. I'll just ask for it through text casually. I just hope it goes smoothly.
