My First Antifoul

Antifouled the boat at the weekend. It was my first time and found it strangely satisfying.
Thought I'd write about it in case anyone else was thinking about taking the plunge ...

The boat is a 20' cabin cruiser (freshwater).
Lifted her at 4pm on Friday and jet washing the hull took just over an hour.
She had less than 1cm of algae and lots of freshwater mussels growing on her (4 years since she was last lifted).
The topsides were then washed down with 'Truck Wash' to get rid of all the dirt.
Also took the time to scrub some nooks and crannies not usually accessible from the mooring.
I own the boat with a friend and we both set about sanding the hull on Saturday.
We each had an electric sander and, starting at 10am, we'd completed about half the hull by 1pm.
A few beers and a pub lunch made the second half a lot easier!
Where possible we sanded back to the gel coat but generally we sanded until everything was firm and could be primed.
This was by far the worst bit of the entire process. Arms were really aching 'cos we had to push the sanders upwards against the hull.
The boot line was then masked and we noticed a few knocks that had gone through the gel coat (about half a dozen very small nicks).
These were filled with gel coat filler - which took an hour to harden (just enough time for another pint!).
We rollered on a coat of very glupy primer at 5pm (took about half an hour).
Back at 10am on Sunday and we rollered on a coat of antifoul. It dried so quickly that we immediately applied a second coat.
Removed the masking tape and set about polishing the topsides ...
Buffered topsides using G7 rubbing compound.
Polished using car polish and an electric buffer.
Also managed to fix a leak on the aft cabin and gave the outboard a bit of a scrub.

There she was at 4pm Sunday ... looking very good indeed.

Considering I hate DIY, there was something very satisfying about the whole process. Even bonded with my sons while we all sanded the hull together.

I must say there were some sad old boats in the boat yard - you'd have to say they were 'no hopers' but I now understand why people just tinker with them.

As for our boat - she's due back in the water any minute now and it's great to know the hull's in great shape.

Costs?
101.44 Boat lift and hire of jetwash from marina

Sanding Antifoul? Be very, very careful!

This stuff is meant to be toxic! Do not sand it dry, and you should wear full protective gear.

The modern copper based formulations seem not so bad, but with TBT the consequences could be severe. I had a friend rushed to hospital a day after making this mistake, he was off sick for a couple of months and has suffered permanent lung damage.

Blimey!
Luckily we were all wearing goggles and top-knotch face masks and nobody was rushed to hospital. I'm not convinced there was much of the original antifoul left - we seemed mostly to be sanding crusty old brown dirt.

Top tip though!

I'm curious, if you have never antifouled before is this your first season with the boat? It seams like ownig a house an never having spring cleaned. Anyway I know exactly what you mean about the sense of a job well do by youself. A tip for next year, now its all sound and dosn't need sanding back just lean against a post and do it between tides, you can imerse antifoul very quickly after painting and this save the main expense which is lifting out!
