New life for the "old" Buc

Nice!

Just signing on to the thread, amazing reading! Although I feel a bit guilty having binge read through the 24 threads as well as the 28 plan hunt and missing out the actual long process you all went through. I'm not jumping on a build just now, I like to study well before I make a move. So far I'm very much leaning towards the 24. More economically built and lotta boat for less complexity.

+1.

 

Yeah and then there's the other tick in the 24's favor as well, and that's you os! Can't beat that first hand knowledge any day! If there still available I will definitely be contacting you in regards to a set of plans. As I said not jumping on a build straight away but always helps to study,study, study. After all the fastest way to do anything is still once, and right. Also with added time parts can always be premade as well. Just as some background I'm a hardwood contractor so the tools nor the materials are foreign to me. Grew up in a family of builders as well as an uncle who is an amateur luthier so an appreciation of wood selections really led me into wood working.

Marmoset. (Barry).
Thanks for your interest.
Go to the "Buccaneer 24 Builders " thread, Page 120, Post #1792, for the latest information.

 

Oh these threads have been my bible for a month now, so yeah, already familiar on the rundown in regards to a p.m. Even had a laugh at the thought of needing 5 post to make a p.m. There's so much info in there that there's a million questions come to mind! Granted most of which will belong in builders thread I think.

plans for the 24

I have a rig from a Tornado cat with sq top main and a larger jib the upwind area is about 290 sq ft and the spinnaker is 270 . would this be a suitable rig for the B24. And who has the plans for the 24 now? Larry

 

Hi Larry
Quickly ran some known figures on your rig even spreadered up the righting moment of the B24 would negate it as suitable.
We now supply plans having taken over continuity of supply from Os7.
PM from here or for faster response email direct inquire@ezifoldyachts.com
Cheers

Rigs

Larry, I agree with OTB- a Tornado rig would probably not be strong enough for B-24's righting moment, and it is also pretty small. I am using a "stock" fore triangle with a 260 sq foot (taller) main and the 24 handles it, although it is best if I put in the first reef at around 18 kts true wind. I like the bigger main, as it allows me to use a smaller and easier tacking jib most of the time. My "small" spinnaker is around 350 sq feet, and I rarely use it- most of the time I use a 600 foot spinnaker and often wish for more area. (except when I am taking it down )
Go big or go home

You'd be better with an 18-fter plan set, like the Scarab or Woods designs and build a tri that way....or do you not have the Tornado hulls to use as the outriggers..??

Rig would stil be iffy though, I reckon, prone to breaking.

I've got the rig off a Farrier 24 and of a 14-ft cat. The cat mast is only a metre shorter than the Farrier's, but the difference in cross-sectional size and weight is like trebled at least.

It's not the height and the size of the sails, it's the ability to resist the much higher righting moment forces of the tri that matters.

When a gust hits a cat it lifts the windward hull, thus spilling air and reducing pressure on the rig. A tri hit by a gust just digs its leeward ama in a bit deeper, which increases the forces acting on the rig almost exponentially.

Or so I've been told by those who ought to know.....

 

"Quote:- A tri hit by a gust just digs its leeward ama in a bit deeper, which increases the forces acting on the rig almost exponentially. Quote:"

In the 45 years that the Buccaneer 24 has been around, there have been no capsizes or pitch poles reported.
That is an amazing fact. I wonder why.
The Twiggy on the other hand, is noted for it's pitch-pole ability. It has low buoyancy amas. Food for thought. :idea:

There is a current idea that the B24 could be enhanced by extending it's amas forward to match the main hull bow.
I can't help but wonder if this would be more likely to trip the boat over if the new float nose digs into the back of a wave.
A wave piercing bow may prove more effective, but has other disadvantages, as Richard Woods has so clearly stated. The same goes for ugly vertical stems.

Crowthers bow bulbs have proved very effective and can be easily constructed from foam/glass/ epoxy.

 

Bucc24: based on the history you so rightly quote, Crowther seemed to have hit a sweet spot in the relationship of the amas to the mainhull and to the sail plan. From the pics I've seen of the Green boat burying the port float - it is totally amazing what the boat is capable of in the hands of a good (great?) crew.

Twiggy: not sure if there are other cases... but from my reading of the boat's history the pitchpoles (and hull #1 twice by the same owner if memory serves) took place (a) at high speeds, (b) in big breeze, (c) going DDW, (d) in big/steep waves, and (e) shorthanded. Not sure any trimaran could have done better at the same speeds in the same conditions (says the obviously biased prior owner of a Twiggy ). Don't have any info of a Twiggy being 'sailed over' as opposed to stuffing the bows when going DDW.

OS7, you probably remember the anti-dive-planes Lock added to the Twiggy main hull plans after Ian (Johnstone sp?) did his stuff up on the way to the OSTAR that was so well cover by the media.

 

Yes I do----and they proved to be a two edged sword in some circumstances.
When a nose dive is well and truly stuffed the anti-dive planes could derive a negative AOA which would then contribute to a pitch pole instead of preventing it.

 

What do you mean by "Crowther bow bulb"?
