Leaving Boat In Slip

Recommended Posts

sandaddiction

Hi

 

I have a fairly new 2016 Malibu and am considering leaving in the lake over summer.

 

1.  What are the downside to wear and tear on the boat?  Would removing it every few weeks help?

2. If the boat is properly tied down, is there risk to damage the boat?  Does anyone have pics or a diagram on how to properly tie it down?

 

Thanks

Biggest downside is that gelcoat tends to blister when left in the water for extended periods of time.  Ideally, if you are going to leave it in a slip, you might consider investing in a lift.

But, yes, removing it every few weeks to let it dry out, and to wipe off the scum, and, perhaps reapply a wax/polish gelcoat seal, helps.

There is always risk to leaving an unattended boat tied down in a slip, but there are ways to minimize that risk.  Go to the "Search"  tab on the tool bar and look for "mooring in slip."  There are a few good threads I pulled up, including pictures.

Definitely do a lift, worth every penny (if they allow it).  This is our set up.

If you are going to leave it in the water for extended periods of time I recommend doing a quality bottom paint and barrier coat to prevent blisters and gel discoloration.

 

Gelcoat looks like it's completely hard and smooth to the eye but if you look at it under a microscope it is porous, like a sponge. Water can migrate into and behind it.

Mine sits in the water for about 5months straight through the summer into the fall. Never had an issue with blisters. Some boats do blister and with the cheaper polyester resins, they can. Mine does discolor during that time, but a quick acid wash and she's white again. You are rolling the dice with leaving it in the water in terms of blistering, but more don't than do.

Gelcoat has changed quite a bit since 2004, thank the EPA for it.

Interesting.  Can you elaborate?

Have had 5 boat from 3 manufactures in this spot starting in 1990, not the best place to dock a boat with no water movement.  I pull the boat about every 2 week, gas,hull cleaning and a quick coat of RejeX polymer coating.  Not a single problem.

I've been out of the boat construction following for a while. I'd be interested to hear any specifics on this. I know it used to be most boat manufacturers of pleasure boats used polyester resins for the gel, cheaper and easier to deal with. Higher end boats like Grady White and Boston Whaler (usually fishing boats) and possibly Formula (can't remember them all) used Vinylester resins in the gel which were much more impervious to water and blistering. It wouldn't surprise me one bit if the EPA eliminated a lot of the good stuff needed to make good gel coats though.

Beautiful boat.  Just curious, why no boat lift?

Pretty much total elimination of styrene to lower VOC emissions from the manufacturing process. It really changed the properties of gelcoat, for the worse.

Slip is to small for a lift, under 9' wide, 6" between boats and 3" at the dock along with being very mucking.  (You need to have a good dock partner and neighbor)

Thanks

I've had two 'bu's blister. I'd usually pull the boat(s) at least once a summer, wash, etc. I dont notice a performance difference. From 8' away you wouldn't see any issue, but up close it's not pretty.

I wont leave my 2002 in the water though for this reason.

It's a non-issue. We have over 1100 tenants who keep their boats in a slips, none on lifts, probably 200 of them in Malibus made after 2012. Zero osmosis/blistering problems. The last boat I saw with the problem was an MC built in like 2004. My own 2005 has never had a problem & spends weeks or months at a time on the water, year after year.

Might find more on here if you search. Malibu also says bottom paint if left in the water in the owners manual.

Where is this marina?  We don't have anything near that big around here, even on Lake Minnetonka.

Seems like the OP @sandaddiction drifted away.  I wonder what kind of water he's on: Mountain, Southern, Midwest, River?  Makes a difference for scum, minerals, etc.

I work for a company that owns 3 marinas on Lake Couer d'Alene. Plus we're a Malibu dealer, like #8 in the country. Plus Cobalt., Regal, & Harris. I think the only boats I've ever seen that were bottom painted were brought in from nearby coastal areas (Seattle, Portland, California, etc.).

This is a good way to kill the resale value of your boat.  Most buyers will quickly pass on a wakeboat with bottom paint.

So right. I looked very briefly at one with bottom paint, can't see what sins it might be hiding, and it had obviously been beached, so I passed. 

Told the to have it removed, and I might come back.

Thanks for all the feedback.  After reviewing everyone's comments, I don't feel comfortable leaving a nearly new boat on the water without a lift.  The downsides far exceed the added convenience.

 

Thanks again for all the thoughtful comments.

Was talking to Chris Travers Friday about boats staying in the water.  They have 3 Nautiques that sit in the water for weeks at a time and never had a problems.
