We love the concept of the 580 but a large part of our usage would be day sailing and cruising off a trailer. I think that would be tricky and time consuming with the fixed keel and the ramps we normally have access to. Is there a possibility of another, more easily trailable, keel that could be bolted on in place of the fixed keel when the boat is not being used for class racing? I am thinking of something like a shallow steel/lead shoe with a recess for an unballasted centreboard (eg B&B design Mathew Flinders bandbyachtdesigns.com/mf246).

Hi...at this time we are planning later this year to develope a lift keel vesion of the Globe 5.80. We are simply too busy for now to work on that. The "Initial" principles of this are that the Steel- Lead bulb keel will be installed in a High Keel box and use a verticle lift up and down action. When down it will be simply and quickly secured watertight from inside the cabin, giving full self righting at 142 degees AVS for true Ocean voyaging. While the hull can be safely manouvered with the keel up, that is only for launching and navigating shallow water, calm water and is NOT meant to be a true sailing option. This allows a much simpler self launching of a BIG Traier sailor The undecided point at this time is can we allow it to be a true Globe 5.80 One design for events? At this time I very much duobt it, as the keel would have a different Blade pofile, but lets wait till we start looking at it. Thanks...

My guess would be that if the lifting keel was drawn in from the get-go, more people would be interested, not only as a race boat, but also for more day sailing as being far easier to launch from a trailer and or ship in a container without having to deal with cranes/forklifts bolts and tubes of sika-flex. Not difficult today to design a solid keel box and locking system to keep the keel in place. Bit late for that option as a one-design.

Thanks Ian...One of the challenges for normal production yachts, where a big market is the aim, is creating the boat/design good for everyone, but the 5.80 is not that type of yacht. This is built as a One Design for a special group of serious ocean adventure sailors. It seems to be working. Having created that new 5.80 class there is now a growing interest in a lift keel version. Personally, I do not want to live with a keel box, nor pay the extra cost of making it and the specially engineered keel etc. I love the 5.80 just the way it is. But I am happy to develope a lift keel version as soon as we have time for a whole new group. It may just be popular as well . We are so busy right now with 5.80 sailors in 20 countries it may not be before the end of this year..but we will try. ..all the best..

I gather it adds complexity to have a retractable keel, but where I live (Vancouver, BC) marina space is tight. I'd be interested in how much weight would be added, and what it would take away. From the location of the fixed keel, would appear the retracting mechanism would be sort of hard to get around in the cabin area.
I'm not in a rush; will be happy to wait until later this year to see how this might work.

Hi..yes your right..there will be a BIG box structure right where you do not want it and it will not be a 5.80 class boat as it will be different underwater etc....But a cool boat none the less... so check back in 6 months

I used to import the Zero Mini Transat 6,50 designed by Marc Lombard & I owned one for 2 years.. It was the only Mini that had a retractable keel. The keel was bolted on ana alum frame inside the hull. Relaesing the bolts allowed the boat to be lowered so the keel came up into the cabin. The bulb remained exposed a few inches underneath the hull. The idea was that with a canting cradle mounted on a trailer the boat could be towed legally in Europe. Over 40 Zeros were built - no keel losses or damage to the hull as far as I know. Not possible to raise & lower the keel in the water. Check Lombard's website & the Zero builder's sites if you want to see this design. With a canting cradle I could import 2 Zeros in one 45" container. That made he shipping costs from Spain more affordable one 45 hi cube vs two 40' hi cubes. The 5,80 makes great sense for shipping - one 20 ft container - but I think the mast would need to be in 2 sections.

Yes the masts of 5.80's have a sleeve just above the spreaders to breaks to 4mtr x 2... Thnx

He now offers plans for a cruising version with a lifting keel. I doubt that the interior is so compromised by the lifting gear & the keel box that it greatly detracts from the Dix being a good cruising boat. You can check out Dix designs & there are several Youtube vids of Dix Minis under construction.

Je suis d’accord avec vous, je pense qu’une quille rétractable peut être un vrai p^lus pour ce bateau. Déjà cela permettrait de naviguer ailleurs qu’en mer, par exemple sur un grand lac (comme chez moi), où il n’y a pas forcément d’endroit pour les mettre à l’eau, sans grue. Et puis cela permettrait d’offrir une vie supplémentaire à ces bateaux, envisager d’autres options... bref quelque chose d’intéressant qui pourrait correspondre à l’esprit de la classe. En tout cas, je franchirai sans doute le pas (j’ai déjà les plans) si jamais on peut adapter cette forme de quille. Sinon, les possibilités sont tout de même réduites, à part si l’on vit au bord de la mer bien sûr ou que l’on dispose d’une mise à l’eau qui permette cela.

Salut .... oui c'est une option qui peut arriver à la fin de l'année ... mais à ce stade, il ne sera peut-être PAS en mesure de rencontrer le même Globe de classe 5.80 car la quille peut être différente etc. mais nous déciderons cela dernier .... alors bonne chance là-bas ...

Merci pour ta réponse Don ! Justement, tu peux m’en dire un peu plus sur la quille ? j’ai cru comprendre qu’elle serait facilement amovible ? Dans quel esprit tu veux la construire ? Comment tu envisages la mise à l’eau ? Avec une grue ?

Comment tu envisages la mise à l’eau ? Avec une grue ? Salut..Non ce sera une quille éclairante dans une boîte juste pour le transport donc la boîte de quille sera en plein milieu du passage ... et assez grande mais au-dessus de la ligne de flottaison .... l'ampoule sera sous le bateau sur la remorque la quille dans la cabine avec un treuil ... vous lancez la remorque .... il faut donc une bonne rampe ou attendre la marée ... puis en eau calme ... vous abaissez la quille ... le caisson de quille et le dessus de quille ont tous deux des brides ... vous le verrouillez ensuite sur un joint pour qu'il soit maintenant posé et vous naviguez ... vous ne pouvez pas le soulever en mer ... au retour vous déverrouillez la bride de quille et le treuiller ... puis montez le bateau sur la remorque toujours avec l'ampoule sous la coque, donc besoin de beaucoup d'eau .... donc pas un marin de remorque mais toujours possible ... merci .... Don
