New purchase, needs bottom paint, no trailer

Hi re the sink the ball **** is probably to close when under sail. When the boat is hard over in a fresh wind the water will come up the pipe. Close it off u could also fit a 1 way valve as a precaution for when u forget. Always always double clamp your nylon pipes and check all your ball cocks are in good nick when u slip it if the hull is steel good quality plastic ones are best to eliminate electrolysis for example a nice brass one will soon a good chance to check rudder and stuffing box for the prop change anodes if any are left. Good chance the prop will need replacing after 4 years!

Re: New purchase, needs bottom paint, no trailer

Okay, lot of information required to answer a simple question!

To repaint the bottom, the boat needs to be hauled out of the water. it should immediately be pressure washed - if you don't, any marine growth will set like concrete.

You then need to prepare the bottom. This normally means sanding, and in some places repainting. Some repairs may also be needed. One catch is that bottom paint is incredibly toxic, so you will need a special sander that vacuums all the dust, complete body covering (including head/hair), and quality respirator. Your boatyard can probably advise. How long will this take? How fast can you sand! Say 1-2 full days, could be more if you hit problems.

Then, when the bottom is prepped (and any repair work done, like that pesky through-hull) you can paint the bottom. Mask first, then paint. Again, wear protective clothing. Roll on one or two coats - two coats will last longer, but at $250 a gallon for typical bottom paint, you may just put on one coat! Say one day per coat, depending on temperature. (Don't paint in the rain, or in freezing conditions)

Now ask the boatyard pretty please to lift up your boat and then go to lunch. Why? So you can paint those parts you could not reach while it was on blocks!

After lunch - splashdown! you're done!

(kinda a brief summary)

Re: New purchase, needs bottom paint, no trailer

I do my 44 ft boat in 5 days with haul and splash on the 1st and last days.

24 ft 3 days max.

Make it easy on yourself and motor up to Rocky Point. They have a great boatyard and will haul and paint and dump you back in for a reasonable price.

I do have a trailer, currently in need of a storage spot. Unfortunately, it's for a 23 foot Sundance. I've been debating selling the darned thing, as I can't even keep it at my marina's parking lot because people come in the night and steal trailers.

I've used Maine Sail's site to help on my current project to replace a seacock/thru-hull. It's easier than it looks.

Take care of that bottom work. You don't want it to end up like this boat that was seen: THE BIANKA LOG BLOG: BARNACLES AND BENETEAUS

Mainsail who contributes to this forum at times has a nice description on his site.

Re: New purchase, needs bottom paint, no trailer

If you figure out the type of seacock you have, and get the parts and supplies together before pulling the boat, you might get it all done in 3 days. That assumes the bottom is in ok condition and does not need epoxy work etc.

It is too bad there is not a yard where you can do the work yourself without hauling the boat on a trailer. Most of the time the boat is pulled, put on jackstands next to the water and then re-launced from there. Make sure you research this. Becuase of environmental laws some work in my state has to be done by yard workers, I recall sanding is one. Pianting and seacock work should be OK by owners.

Re: New purchase, needs bottom paint, no trailer

My sink works as same... as long as the hose/sink is always above the waterline (significantly), having the sink drain below the waterline is fine. But like others said... if the seacock is frozen, and you start wrenching on it in the water, oh, that'd be a mess.

I've also read that there are several through hull seacock types. Some have a flange, and are surface mounted from below. Some have a flange and are counter-sunk but also surface mounted from below, a final type are surface mounted from inside, and flush mounted. The last type are a huge problem because as they fail, they basically break off easily from the hull, leaving you with a hole. I know of others from the Catalina 25 forum remarking that there was a few years Catalina did this on their trailerables, and they then changed how they installed them.

Either way, fixing that seacock should be done out of the water, and should be addressed as to the real problem (might be more than a stuck valve).

Re: New purchase, needs bottom paint, no trailer

Working on things in the water like OLD VALVES that WILL BREAK WILL SINK THE BOAT unless you just real lucky

You have to invest in a trailer which will pay back over time and you still need a place to keep the trailer 365 days a year

OR pay for the boat to be blocked on jackstands

Re: New purchase, needs bottom paint, no trailer

I've got 2 sinks, the head outlet, head intake, engine intake, and 4 scuppers, they all drain below the waterline. 9 seacocks...
