Keel types

I'm interested in the Enduro 54. Does anyone have any advice on a wide beam monohull with a bustle(very shallow draft long keel) with a centerboard for world cruising. It has an avl of 120, stability index of 52, and a capsize ratio of 1.94.

Re: Keel types

Interesting, no Enduro boats listed on sailboat data, wondering where you got your data from?

Re: Keel types

In many cases I don't think you need a centerboard for "world crusing" if you mean bluewater cruising crossing oceans, but if you are doing Bahamas or other places where you need a shallow draft, then centerboard would help immensely. Otherwise full keel would be top of the list followed by fin.

Re: Keel types

The website is all computer generated images. Is this a concept that has yet to be built?

Re: Keel types

Yes. Hoping to have it built at km yachts. You can find the concept at Enduro54.com. Thinking about having the centerboard modified for more ballast.

Re: Keel types

This thread is much liking asking do you prefer blondes or brunettes as there must 100's of differences between keels, too many to enumerate them all here.

The first question you should ask yourself is what type of cruising or racing, or cruising/racing do you plan to do ?
Where ?...etc....??

This will drive the first key point, which is draft, which is married to the second question..

Which is the ballast, how much is needed, and how deep does it need to be placed, etc, which will dictate keel void space...etc..etc..

Your naval architect would be the best person to ask this question as he/she should know all the parameters of the boat design and should be be able to give you the most informed answer.

Finally, the day will come, when you will want to sell the boat, and whatever you decide now, will also have to please any future owner.

Should be just fine.. Keel up for downwind sailing then vary the depths as the wind moves forward..
Just think Ovni...

I understand the idea of shallow draft for "ice work", or the Bahamas, but a capsize ratio of 1.94 is a high number for an offshore boat.
The number "2" is often tossed out as the dividing line between offshore and coastal, the further under 2 the better for offshore.
Depending upon adding a lot of weight to a centerboard for increased stability is chasing diminishing returns, requiring much more "beef" in the pivot and mounting scheme as well as the lifting gear.
Centerboards are, "generally" for increasing weatherly ability on the wind, not as a means of gaining much in the way of stability.
Of course, when you go to "vertical retracting/lifting" keels that's a whole different ball game.
How many of those designs have been built?
How pleased are the owners with them?

Re: Keel types

Thank you for thoughtful answers and humor. Blondes, no Brunettes, no Blondes. LOL. I suppose what I really want is a completely customized boat. Heavy ballasted swing keel with bustle as well, and with a greater lwl/beam ratio so I can get the stability numbers I want. I'm not racing so my emphasis is on safety. Being able to access more sheltered places and beach is a big plus.

Re: Keel types

Not sure about all your different criteria, or price range, but Southerly Yachts are a pretty nice swing keel bluewater option.

Older models can be found for substantially less.

Re: Keel types

My criteria is very demanding. Alumninum hull, pilot house, high stability swing keel explorer type yacht. Internally cooled hybrid. Kickback rudders, induction everything. Don't want any propane onboard. The only holes I want in the boat are for the water maker and speed wheel thingy. Single handed sailing with protected cockpit. Just to name a few.

why use a thru hull knot meter. just use GPS.



you will need holes in the boat for drains for sink, heads, bilge, water intakes for engine cooling. Possible holes for hvac cooling... unless you do some sort of a "sea chest" type arrangement to minimize holes...

If you plan to go inside this yacht you may need one additional “hole” for a companionway!

Re: Keel types

GPS will fail in the event of power outage. I meant through holes below the water line. I would like internal hull/ keel cooing which does not require sea water along with dry exhaust or a pair of gensets to recharge battery bank. Thanks for bringing up sea chest. Hadn't thought about HVAC.

.... I assume that is a sexual joke. Of course I will want a co-captain.
