Lift out, wash, antifoul, back in

Minimum time is probably 24 hrs. But lots of lift-out facilities offer cheap "summer scrub" rates with up to a week on the hard - plenty of time for polishing the topsides too. I do this every 2 years.
 
depends on how many coats of antifoul and how big the boat is........same working day should be easy but anything less could be a rush

minimum drying time is an hour for the antifoul, you'll need to rub down the old antiifoul to key it beforfe you start, so assuming two of you can apply a coat in an hour, and the rub down takes half an hour of just scratching with wet and dry, that's three and a half hours from when the pressure wash finishes.......and of course you'll need the hull to dry before you start antifouling although you can sand it wet but you'll need to rinse off the antifoul dust......so the drying time before you start antifouling will depend on the weather and you need to add that to the three and a half hours

of course if you are masking difficult bits and doing boot topping that takes more time

you might need to think of one of you applying masking tape and the other starting to antifoul immediately behind.........i found the masking tape application took a bit of time

did my boat not so long ago and i think the times above are reasonable
 
but of course that depends on the yard hauling out early and then being able to refloat the same day

same working day is possible but why the rush? agree that 24 hours is probably more sensible - out today back tomorrow

Well we've done it (as have many many otters) between tides. Just drying out on a wall/grid or piles - as soon as you get welly deep you can jetwash. On a 30 footer or more one end has dried by the time you've got to the end.
DON'T sand the af (unless you have the kit so you don't breath it in!) then just apply the af. Can easily get two coats and mask the waterline in a couple of hours. Then have time to sit, eat a fish'n'chip tea and watch the tide slowly rise around your vessel.

The boys at the Cowes sealift2 don't take 24 hours. But it does depend on how much prep and what af you use.

That would be my experience as well - but as per fireball I don't sand back AF one year to the next - a good pressure wash when she comes out at the end of the season is good enough for me.... so jet wash (30-45 minutes), mask (15-20 minutes), antifoul (couple of hours - two coats), unmask (10 minutes), wait for paint to dry...

I'm fascinated by the guys who operate the hydraulic jobbies up the Medina from Cowes - I'm assuming they work in terms of hours instead of days as well... :confused:

Not sure what the minimum time is but this year had the boat (31ft fin) out for the weekend. All done solo - b crew always busy elsewhere.:rolleyes:
Boat been pressure washed & nice even AF from last year almost all clean.
Fri evening - 1.5 hours to go over with wet green "scouring pad" to smooth off and do the sling marks missed by the pressure washer & rinse and mask up (single row of masking tape)

Sat am - 2.5-3 hours to AF 2x around waterline, leading and trailing edges keel, 2x rudder & P bracket; 1 x rest of hull. Used 4 x 4" foam rollers. Remove masking tape.

Late am. Change shaft annode. Polish propeller & shaft.

After lunch. 3-4 hours to go once around hull with McQuires Clean and Polish and once round to remove/polish (all by hand up & down a ladder.)

5.30pm all finished, showered and changed & off out for the night!!
 
just a further bit about the sanding - we were advised that sanding does help the new antifoul to stick, but we always do it wet with a hose running so there's no 'dust' although the antifoul colours the rinse water and can be seen to run off

that was the 'dust' i was referring to............
 
Anti foul dust is a toxic as asbestos fibres, and I prefer to leave well alone unless getting the whole lot stripped off with "slurry blasting"
If you want to "key" the old surface use a wipe of thinners to make the surface tacky... its mucj quicker too, if you are ding it to a timetable
 
Add to the foregoing items, removing and regreasing seacocks to the loo if blakes type, also use the pressure washer to clear the cockpit drains - before you antifoul.
We also use the pressure washer to clean the teak rubbing strake - comes up like new.

Am going to try my own suggestion to use silicone spray on the propellor blades if they are fouled much when we scrub.

We have ample time to complete all jobs mentioned between tides.
