hi farmhand.
back in 13/12/07 you submitted a link for a dingy liner.
then on another forum you briefly showed a home made
liner you made for your dingy.
i was wondering if this would work for a larger boat(25'swing keel)
and how you would go about making it?
the frame is obvious(kinda). but the liner is not so.
would you use tarp(plastic) or canvas?
then, if i read this correctly, one would use pool cleaner
tablets to keep everything clean.

or is this just a waste of time?
am i going to polute my lake? lake perry, ks. sorry, it's already polluted by stinkpots!

by the way, this is for my friends boat. i wont tell you what it is,
just in case i get screamed at

any other lakers welcome to pitch in.

you e & w & s & great lakes sailors, ??????????????????

thanks,
iain

i don't have a boat as yet, but give me a chance!

Iain,
I have thought of a similar home-made method to protect my hull from bottom-growth.
My (imaginary) method would not require a frame like a commercially available product.
I thought I would buy sheet plastic, 10 mil thick or so, 20' by 100' roll and cut off maybe 30 +- feet of it.
My idea would require two people, I think, to pull the plastic under the boat while at the slip.
I could secure the plastic to the lifelines, start at the bow and walk it aft pulling the plastic back under the boat. (I have a swing keel so I think we could coax the plastic under the raised keel.)
When we get the plastic back to the stern, we'd secure it all the way round the side of the boat, then add the benign chemicals that would keep too much growth from happening.

keep guessing oscar.....you're getting cold.

dave, interesting idea. i'll have to pass the suggestion on.
what kind of benign chem's would you use?
i had thought of pool shock, but i think that is a pollutant.

Fairly common here, there are 2 companies selling heavy vinyl liners that you install in the slip and keep the boat in. These are made of vinyl, styrofoam, and PVC. They do require their own cleaning once or twice per year. Pool chlorine is used to keep the water inside clean.

Here is one of the two: bottomliner.com

http://www.bottomliner.com/

The other one is known as armored hull.

Cost about $1500, installed. You can sometimes pick them up used.

Much more popular for the powerboat crowd.

For a long time I've had a similar idea- but it's more of a 'skirt' than a liner. Plants can't grow w/out sunlight, so if you rigged some sort of plastic sheet all the way around the boat, hanging 2' or so below the water, you'd block out most of the light. Which is also why I always try to find slips that run east-west, and dock the boat on the north side of a finger if possible- the dock will shade much of the south sunlight, and it really does make a difference on how much growth happens on the bottom- especially if your marina has a tall dock and you live in northern climates where the angle of the sun rarely gets above about 45 degrees.

<font size="3"></font id="size3">Iain, my el cheapo dinghy bath was a bust so I dismantled it. I understand the Bottom Liner company is about to come out with a less expensive one ($500.00 now) based on one of their reps eyeballing mine! As to a home made for a 25 LOA: fugetaboutit, pop for the Bottom Liner, new or used.
