Lagoon 420: anchor roller problem.

The design & build of the anchor roller on the Lagoon 420 (at least the 2009 model I'm buying) is slightly flawed. Due to the bowsprit (which is structural and supports the forestay), the anchor can't be flush with the bow.

The leverage created by 1/3 of the roller being unsupported is substantial. This could have been fixed with appropriate backing plates ... but Lagoon didn't install any!

So ... the prior owner of this boat apparently ripped the anchor roller out of the deck (damaging the bow).

Repair 'like original' is going to be done pre-purchase, but making it better structurally is falling on me - pics of that will come soon. Solution may be a bit of overkill, but being able to trust the anchor to hold is important.

Advice to other 420 owners/purchasers: put a backing plate in place NOW if you don't have one ... also probably not a good idea to put all the strain on the anchor roller & windlass if you are ever stuck - the bridle is there for a reason (though you may also want to increase the surface area of the backing on those).

Ours is set up differently it attaches below the beam and attaches to two ally slides that reside in the sail tracks that are part of the forebeam extrusion.

The bolts on the underneath slide had corroded badly (no DURALAC had been applied on assembly) these threads were totally compromised and failed whilst retrieving the anchor under fairly normal circumstances.

Replacement is just under 3k for components from LAGOON, i bought it back to Australia on this trip and had it straightened by pressing, i'll take pics next week on assembly.

Check the corrosion on the beam, those insulator pads did nothing. Interestingly i had to drill every remaining bolt out to remove the bracket.

TIP = Go over every bolt undo and treat with an anti-rust such as DURALAC or equiv. Cheers Frank

POH, I wonder if the L400 has the same anchor roller set up? The boat we are looking at buying also is in need of repairs to the anchor roller..... interesting!

Lagoon4us (Frank), you have a PM, BTW.......

[Lagoon4us]

I think they go over the beam not under, i've been checking every cat i see to get different ideas... PM Answered Cheers

The L400s I've seen all had the 'traditional' system of anchor mounted over the cross-beam at the bow - much better support & less loading, but the corrosion issue that Frank pointed out on his Lagoon is probably there with all of them.

just a question why not flake the chains out before you let go and when you want to pull her up attach a roap to the chain and back to a winch it saves your back as well, honest i got gaught out when anchored off gib last year,

Keep it clean and get off the salt, then it will be a lot better.
get a fresh pump to hose down all around the anchor.

All Lagoon's have an anchor winch, not sure why you'd want to flake the chain out prior to anchoring i can see gel-coat and toes getting seriously damaged doing that.

Has nothing to do with keeping it clean these fittings are mounted to the fore-beam the issue is the bolts used for mounting were never coated in DURALAC and being dissimilar metals corrosion will occur with any moisture fresh or salt.

OK. will keep a good look at mine, and se what happens.

Hi All ,
Last year i spent 18 days beating to windward crossing the Atlantic, a few miles from horta, the mast went over the side the boat in question was a lagoon 40 footer. nice boat, the problem was the bottom t piece on the stb rigging failed, we'd had the rigging checked out by a well known company in Tortola, they missed it, as when we got the riggging and mast along side you could see by the crack that it had been going for years, ive wrote this for you all just to be aware of this and if you can get a blue dye test on this part of your rigging, i hope this helps. apart from that ive had problems with the 3000 kv set on a diesel set on an electrical . motor lagoon we had to take the pump off the shower out pump and rig it to the intake pipe of the gen set to start her after that she worked well , after eight thousand miles in lagoons that the only problem ive had, except for one lunatic crewman

Thanks Tony. That's great info, thank you for sharing. Dismasted after 18 days just out of Horta! Not much fun although better than losing the mast half way between Tortola & Horta, I suppose.

Note to self, check the rigging thoroughly......
