Packman, thank you for your thoughts. I really want to run this one to ground. The prospect of being able to slip my boat, saving ~$12,000 or more by using a Boat Shield or something similar, is worth considering heading to the marina more frequently than I might otherwise.

I'll see if I can get the company to tell me what they recommend for chlorine treatment frequency.

I would think that this would work pretty well at keeping hard growth off (the need water flowing to eat), but with out the chlorine you still would deal with alagae and slime. I would be a little concerned that chlorine would have the potential to wreck some plastic and or rubber type stuff. In my younger years as a pool guy I learned about how damaging chlorine can be.

If it were me, I would just forgo the chlorine and hit the hull with a power washer now and again. Actually I am me, and I just bottom paint.

Default Looking for same fix - anybody tried Barnacle Barrier

Looking into the armored hull, and came across the barnacle barrier. Website link to follow - anybody have any experience Gulf Coast waters??

resurrecting this thread. Hoping folks who own any of these products can update us on longevity of the product. If I knew it would last 8-10yrs it may make sense....

I had to sell my boat due to cancer, but it was a 23’ aluminum Munson Landing craft. I wet slipped it in San Diego in an amourhull. The unit lasted over eight years and I sold it when I sold the boat. It worked exremely well for my boat. They are a local company but I have no association with them.

I looked at the site because I keep my boat in the water,but it sits for extended periods without use. I have someone come and clean off the growth,but it is the waterline turning yellow that deprives me crazy. That being said our conservation official would never let us add chlorine to the water. A neighbor who lives adjacent to my slip wanted to put a pool on his property. Conservation denied the permit out of fear that chlorinated runoff would get in the salt water.

It is a little hard to believe that it would be legal to leak chlorine into any body of water. If I saw (and smelled) my canal neighbor doing it i'd have to say something.

The volume of a canal is probably roughly a million times greater than the volume within the barrier so the dilution of chlorine would result in miniscule concentration.

I used chlorine in a hot tub for about 20 years and found that chlorine dissipates in a matter of days unless there is an auto loader of some sort. Once the animals are killed by the chlorine within the closed barrier no need for more. So, if someone boats once a week, then there would be no chlorine release. I also wonder if there is a dechlorination chemical like used in aquariums for chlorinated public water that can be dumped within the barrier for instant dechlorinization.

Yeah.... but the OP is in California where they are trying to outlaw normal bottom paint. I doubt the state would be OK with a product like this.

The product is made and installed in California so apparently there aren't regulatory obstacles. The OP should call the manufacturer for details and the county or state regulatory authority.

My point is that the amount of chlorine released, if any, is so minute I expect it is immeasurable.

Agreed! But it's California.......they'll approve it today and fine you for it tomorrow. I remember many years ago styrene was a carcinogen - in California and France but nowhere else!

Using this logic, any one person's pollutants usually result in a miniscule concentration, so why outlaw any?

Assuming chlorine in seawater is considered a pollutant.

To put it in a different perspective, effluent entering a wastewater treatment plant is mostly chlorinated water from public water plants. Many wastewater treatment plants also use chlorination in the treatment process. The EPA is all over these systems and it is common and it is allowed, but mitigated to an extent. On that basis, slip chlorination is not like it is in left field.

Also, I suspect the shield would be effective without chlorination since the hull would not receive water current, nourishment, or high oxygen.

I am speculating and the questions can be answered in due diligence. Conversely, the shield system does not seem to warrant total rejection on these points on its face.

Love that this thread has been resurrected and debate over the issues associated with use of chlorine.....BUT it would be great if more folks with these liners (3 different companies sold them over the past 10yrs) could weigh in.....I am struggling to understand why these liners never caught on. The cost and hassle of using them seems outweighed by the savings and headaches associated with bottom paint/marine growth/electrolysis.....

Sorry to resurrect but thought I’d give people input on the liners. The guys who make them (Dennis at Affordable Marine) are fantastic to work with. My boat has been slipped all season (8months) with no bottom paint. I give the waterline a rub down about every 4 months but other than that the boat stays perfectly clean. Way easy to use. Liner gets scraped for $100 every 6 months.

Default Looked everywhere for information and reviews on these "alternative to lift" products

I am considering installing one of these in Punta Gorda, FL (SW coast). Mainly because I want to avoid the need for a traditional lift which would require permits (which would probably be an issue with one of my outer poles). As I understand it, these are free floating, "not permanently attached structures", therefore no different from tying up a boat to the dock.

Anyway, regarding the discussion of water in the pool - why not install a bilge pump/float switch to simply pump the water out of the "lagoon"? Then no need for chlorine or concern about rainwater, wash down water, etc.

Just a quick not about chlorine as a sanitizer. When chlorine is added to water for the purposes of killing organisms, the result of the reaction renders the chlorine into chloramine. It is no longer chlorine so it won't/can't react with other organisms. If you smell that "chlorine" smell what you are really smelling is chloramine. It has already reacted and off-gasses from water quite readily.

So, if I were to use chlorine for an extended absence in my Armor Hull, I would probably put several floating chlorine tablet dispensers with the vents almost completely closed. That way you achieve a very slow release over a very long time. Using several allows the chlorine to be dispersed throughout the containment area. The wind and wake action in the harbor will agitate the water just fine.

Just my two cents.

Any problems with the corrosive nature of chlorine on metals below the waterline?

I recently started working with a company and there alternative lift system.
Fabdock is similar in that a membrane separates your hull from the river or canal, but it has a pump box in the bottom that pumps all water out from inside. Ripples in the material allow water to drain down and not be trapped against the hull.
if you have any questions or would like a price installed on the east coast pm me.
