hey all, great site.

I will be purchasing a boat in the near future. boat size will be between 16-17.5ft and a 90 horse
There are no docks where my cottage is, it's a shallow lake with beach front and am wondering if it is a good idea to keep the boat out on anchor for when we are not there(usually for a week,sun to fri) the lake waves can get up to three maybe four footers on really bad days.
Also how strong are those bow rings on a boat. they don't look too heavy duty. What kind of abuse can they take.
any good suggestions for an anchor(sand bottom).

much appreciated

Re: ancoring in open water

It would depend heavily on the type of boat. A North Sea Skiff would handle the waves much better than John boat. From your description I would not leave so small a boat unattended there if it were a power boat, even with two automatic bilge pumps. A cuddy sailboat with a self draining cockpit maybe, but for me that would be a stretch.

4 foot waves, 17' boat? Hm-m-m-m, you better have a pretty good anchor. Scares me.

Your boat won't be protected at all? It doesn't sound like it with 4 footers, but if you had a good cover you should be ok, along with a mooring anchor.

Re: ancoring in open water

for that size boat i would realy consider pulling it rather than leave it for 6 days. you will need a good batery and an automic bilge pump
all in all i think the bow eye is the least of your problems

x2.

How big is that lake if you get 3' - 4' waves? I wouldn't even put mine in the water with 2' waves -- 'course it's smaller than yours.

As far as anchoring when you're there, I made concrete anchors, filling a 5-gallon plastic bucket and sinking stainless eyebolts in it. Once completely set, I embedded the anchor so it's flush with the sand bottom. I've used vinyl-encased cable and 1/2" lines with stainless carabiners at each end. On our lake, even galvanized steel chain won't last long, so the setup I described is what most people use. A good water-shedding boat cover is essential. A wind sock to scare away seagulls is a good idea to keep things relatively clean is also a good idea (I've yet to find a really good solution for that, though).

But if we're not going to be there for a week or so, or if there's a significant storm coming, I pull the boat.

Re: ancoring in open water

you're much better to pull it out. At my Dad's place, also with a sandy bottom, we screwed in the large screw in anchors that utility companies use to support wooden telephone/electricity poles (they use a cable from these anchors to up to about 2/3 up the pole). They use them in bogs etc.

If a storm comes up, I'm not worried about these anchors failing, but I am worried about the cable/chain that attaches the boat to the anchor breaking.

We tried a variety of anchors before, and the boat could always drag them. Even 2 tractor rims chained together. Running rope up to the boat would fail quickly. I swapped that out with cable.... then tied a float on with a piece of rope. When it's rough, I don't like how much snap the action of the boat puts on the cable.

My Dad once had his 18' I/O break free of the anchor during a thunderstorm... ended up on the neighbour's stone breakwater. Luckily the drive was OK.... and insurance covered all the refinishing (repairs and new gel coat).

Real solution is we built a boat house for our ski boat.... we never leave it on the dock or on the anchor, even overnight. My Dad pulls his boat out when he's done with it for the day.

Others on the lake sometimes leave theirs on anchor for days on end. Once I noticed a friend's sitting really low in the stern. I went over and turned on their bilge pump and ran it for about 20 minutes. A big boat can collect a lot of rain water in a few wet days. I told him he was lucky and should have a float switch.

Re: ancoring in open water

Is there a reason no one has suggested beaching the boat or installing a boat lift?

Re: ancoring in open water

I think you have good advice here. I would be very uneasy to leave such a boat unattended under those conditions you mention. Also, if you are not using a marine surveyor or a good knowledgeable person to help you buy your boat i will recommend you visit us before you spend your money. I see it in a weekly matter, a new boater buying a "deal" boat to come here later to find you how much trouble you are getting in. We can give you plenty of advise here.

A boat lift is a good idea, but very expensive.

boat size will be between 16-17.5ft and a 90 horse

As far as beaching the boat, it would have to be pulled completely out of the water to be safe on the beach from a storm making 4 ft waves. A boat like that can easily weigh 1000 to 2000 lbs. Not practical to move on and off the sand.

There is another option, there are boat dollies that the boat drives onto, the the dolly is winched out of the water up the beach. Some have high flotation tires, others are meant to ride on rails or tracks. Not too hard to push downhill back into the water.

That's what we have in for our boathouse... we drive our boat onto a cradle, it's on rails, and the whole thing then it gets winched up into the boathouse. Only takes a couple minutes to get it out of the weather.... but it's not a trivial or inexpensive project to build a boathouse or even just an uncovered shore lift system.

We did a lot of launching/retrieving until we got our boathouse and lift done.

Re: ancoring in open water

hey thanks everyone
great feedback
in regards to the post from BF thats exactly the anchor i want. Do you know where i could get one?
My cottage is on lake winnipeg in traverse bay/albert beach area.
The four footers are worst case scenario it doesn't happen to often but i never under estimate the power of a lake that large.
a lot of other boat owners around me leave their boats in for long periods and i wonder what kind of condition that leaves them in.
what i might do is leave er in when im there and pull er out when it's time to go home and deal with the crummy boat launches.

Re: ancoring in open water

Hi again.... on the east side of Lake Winnipeg... yikes, I'd hate to see how rough that water would get on a stormy summer night! I thought you might have been over-estimating the wave height... but nope I'm sure that place can get even rougher... almost like a Great Lake. I once watched a fairly large (~80' ?) boat that looked like a tug boat (but was probably a commercial fishing boat) getting pounded by big waves off Gimili.

Even if you do pull your boat out regularly, yes having a screw in hydro anchor would give you some piece of mind. BTW, I guess I can call it a "hydro" anchor now that we're both locals :) . As for where to get one... I think you'll need to find an "in" with hydro. Maybe if you called them up, they'd tell you if they'd sell you one... or tell you where you might be able to buy one.... or stop in and chat with the line guy next time you see a hydro truck around... maybe if you offered him $40 or so bucks one would magically appear in your yard a day or two later. Ours came from "buddy of a buddy" type of supply line probably involving bottles of rum. They come in different sizes... if I recall right, ours are about 18" or 2' in diameter. Surely you must know someone who works for hydro??

BTW, they are a pain to screw into the bottom. Ours (we put in 2) are in about 5' of water. You put a handle in the eye on top and then twist them in. Problem is reaching in 5' of water. Sure you can swim down, but then you have no power to turn them (turn yourself instead). Way it worked was have 2 guys, one guy standing on the other guys shoulders. Guy on the bottom has feet on the ground, holds breath, stoops and turns in circles. The other guy supplies the weight that allows the other guy to actually get some traction. When he thinks bottom guy has accomplished enough, he allows him up to breath. As you can imagine, it is hilarious.

If you were putting it in shallower water, it'd probably be easier. You'll need to be able to find them again the following spring... we take the floats off ours and let the cables sink to the bottom for the winter.

Anyway, an anchor like this would be handy if you have the boat in on a nice day, and want to run up to the cabin for lunch, etc... but like I said before I still think you'd be wise not even try to over-night it on that water. With how fast a shallow lake like that can kick up there are many nights that appear fine, but then you get a wicked thunderstorm later on. A few times we changed our minds (thought we'd leave boat on the anchor, but then saw a storm coming)... having to out race a thunderstorm/microburst is not good. We're on the east side of a much smaller lake, and even it gets very rough in summer storms.

Good luck!

I can't believe I didn't think of that, considering that is exactly what I do.

Put the boat in the water for the weekend and leave the boat on the trailer on the lake lot while I'm gone.
