400: Can I beach my lagoon 400S2

[darren lim]

Hi, I'm wondering if it will be safe to beach the cat for maintenance?

Guessing that it will be safe (bottomwise). Need to calculate tides properly.
In France they use the tide to launch Lagoons instead of travelift (boat is rolled of the truck onto the hard at low tide) but - they use sort of cushioning under the 'keels'.

L450 beached. Care to avoid rocks, maybe point offshore and run the anchor out in case an onshore breeze and chop arrives before you lift off.

Cool photo, I guess you really have to know your landing spot. How do you protect the rudders and sail drives when backing up?

The rudders are structural and support the stern of the boat when careening. The saildrive is shorter than the rudder. Moving forward the sail drive is protected by the rudder. In reverse it will exposed so back up carefully.

Now, I've only done this once. Find a nice sandy spot with decent tide difference. Arrive at high tide. Drop your chain about 100m from your landing spot and back in. When your ready to go, at the next hightide use the engines and the windlass together to pull out. Chances are the boat will have sunk in the sand a bit.

Remember, you have two hulls and only one depth sounder!

I would not have the 🎾🎾 to even try, l still dream of how much easier it would be to clean.

Dave is that your baby on the sand?

Great photos

Of course you can.
Please video.

Hi Wayne, Yep that is my L450 Magique.

A couple of lessons; I did not realise that the very flat bay bottom changed angles where I beached, so the rudders settled a few inches into the soft sand, but that was not intentional. Myself and a friend brushed the hulls as the tide dropped - WAY bigger job that we thought it would be!

Finally, I would not recommend beaching at high tide - what if the next months high tides are lower? :-) do the maths carefully!

Cheers
Dave

PS - good point 2Wind!! :-)

I've got two of each

(Interphase Probe on Port and standard transducer or Stb)

No problem for the 400S2. We would usually go in bow first and be ready when she floats to reverse off.

Thanks guys 😀

Unless the sand is extremely firm the keels and rudders will sink in. This is usually not a problem. If you wish to keep the boat a bit higher on the hard it's possible to place boards under the keels and let her settle on these.

We ideally mark a sand bank with a weighted float at low tide. This way you get to test the sand to make sure it's not "quick sand". Position boat on sand bank at high tide after first checking the next high tide is high enough to float her off.
A stern anchor may help keep the boat positioned on the sand bank.

Get ready for a swim, and then tie a rope between each of the chain plates. Dive down and make sure they go the shortest route under the boat, that will be towards the aft end of the keels. Grab your "jetty boards".
(You've got those? They are boards, usually 1.2 to 1.5 metres long that we place outboard of our fenders when tying up next to jetty pylons. They usually have a lanyard attached to each end.)
Tie the jetty boards to the rope going under the keels with prussik knots, or a few clove hitches if your knottically challenged, like me. Wait for the boat to settle on the boards which are protecting the keels and keeping the rudders nice and high.

Finally, hope that the incoming water isn't too choppy or swelly as the boat re floats and that your job goes pearshaped before the tide returns. There is nothing so stressful as having a dismantled saiłdrive and an incoming tide!
Here's to dry bottoms!

Beached, but not all the way

Blue skies and bikini in BC? Did you do that on Photoshop, Scottster?
(Fine looking boat as well)
