    Cast iron fin and a lead bulb? Would that create corrosion due to mixed metals? Pehr, do you have any corrosion on the steel fin? Does it require regular maintenance to keep the corrosion on the fin low (like I need to do on my Jeanneau!?!)

    Yet another Bene 'This or That'

    Sorry for the topic - I know how some of you dislike these - but I'm trying to decide between buying a newer Bene 10r or an older 36.7. There's a lot of experience participating here and I really would like to know your thoughts. I am a very experienced shorthanded club PHRF racer, 1-2 nights/wk plus regattas, but also most often single-handed daysailing (with the race only happening in my head). With either I plan to use primarily a #3 and Code 0 on rollers and an A2, masthead in either case (no Class racing here). My wife isn't a sailor, so of course the interior needs to be nice enough for her to stay overnight. A stiffer boat is also better as far as she is concerned. I like the idea of a newer boat/design but the cockpit layout and bulb keel of the 10r trouble me. I haven't seen a 10r in years, but it looks like all jib controls are ahead of a huge wheel (difficult to get around?). The notion of the bulb collecting seaweed (or my spinnaker sheet) isn't appealing. This one has a newer rudder so that isn't an issue. I know the 36.7 and while the deck aesthetics don't grab me it ticks all other boxes - but the boats on the market are getting old... Other things to consider when comparing these for single/shorthanded club racing and occasional overnight? Any other boats I should be considering?

    Yet another Bene 'This or That'

    That is absolutely the case. Alternatively, if there are sail combinations that would still allow a lively sail without the need for the weight. I can do without extra hands. The boats got to be configured to sail without movable ballast. While every picture I see of a 36.7 has 8 people aboard, owners have also told me how easy it is to sail singlehanded due to the cockpit layout and that it sails well with a #3 and full main. Under 8kts or so, I expect I'll play with the Code 0. Does that swing the pendulum one way or another? Are there other boats that either do well or poorly on this criteria?

    Yet another Bene 'This or That'

    Interesting, Kinardly. I will have to look into it. I never considered upping the interior finished. Whatever I would do would have to be completely reversible of course... Hmmm.... (just took a look at the interior... small volume won't cut it and one thing she enjoys is preparing simple/picnic meals aboard. No go on the galley! )

    Yet another Bene 'This or That'

    Thanks, Steele. I've also looked at the 99. Just doesn't hit it for me. Maybe too small? I also heard it doesn't sail to its rating, as does (doesn't?) the 110 which would otherwise be an option also.

    Yet another Bene 'This or That'

    Thanks Alex. I haven't been on one for several year. Sounds like that would disqualify it right off for us. I'm coming from a beautiful Jeanneau, my wife wouldn't stand for it!

    Rudders and roundup

    Hi all - cruising boat/weekend racer here - a lifelong sailor with lots of experience. I have a 35' 'production' boat shoal draft that I'm just not happy with its sailing characteristics. Specifically, it rounds up constantly. Other than alway pushing on how much sail we carry, I've come to believe this is because the rudder for this shoal draft version is cut short as well as stalls out easily even at 15 kts apparent. What does the group think about replacing this with a deeper rudder to keep steering control in an upwind blow? Also, is there more to it than depth and width? Would I be able to use a well chosen rudder from a different boat - say a C&C110 rudder on a Beneteau 35? The rudder depth could go from 4'9" to 6'... would this be enough of a difference to be worthwhile?

    36.7 or 109?

    Hi all - wracking my brain trying decide if the J109 is worth 50% more than the Bene 36.7. I do PHRF racing, short- or single- handed in generally light lake wind. I'm an engineer - 'technical' sailor - racing the polars and trimming sail all the time. We are limited to shoal draft for either (6' max on the lake) and there are few of each available now for sale. Anyone know how they do head-to-head? The PHRF is almost the same. Thanks for adding your thoughts and experiences!

    J97 and PHRF

    I'm considering moving to a J97 from a larger cruising boat. Singlehanding and overall reduction in sail handling compared to a 35 footer is the objective. How does the J97 do under PHRF? I would be sailing with an older, cruising fleet scratch boat by at least 40 sec/mi, but there are also a ton of J80s around to race with. Thanks in sharing your experience!

    36.7 or 109?

    Thanks, Cman. Do you singlehand the boat much? My kids are grown now and truth is for the most part the boat will be daysailed singlehanded (and a weekend couples camper). Yes - only one marina in the lake can handle sailboats of this size and its in a cove that I regularly read 6.6 / 6.8 ft. Marina warns at anything over 6'.

    36.7 or 109?

    Thanks, Jackdaw. I think if I do go the Beneteau route, I'd sail it with a 105%, fit it for a code 0 and an asym - AND - have lots of bank left over compared to the 109.

    Engineering Career in Sailing

    I'm a mechanical engineer working for a company that produces textiles and plastic films. I occasionally work on new (exotic) components for sail manufacturers. There's a TON of tech in sailmaking - structural analysis, aeromechanics, SAILING. We are also involved in composites for aerospace. I was able to apply some of the 3Di flexible composite (sail) concepts to a project we did for a project making process components for composite wings at Airbus. Both structural (rigid) composites and flexible composites (sails) are very complex with lots of progress to be made. Structural composites is an awesome field of engineering, although epoxy/fiberglass for consumer boats is already well understood and practiced so unless you get to work on exotics its all just plug and play. Roll back my career a few decades and I'd be knocking on some of the sail cloth or sail makers doors..... YMMV - good luck and keep us informed!

    Rudders and roundup

    Thanks, Cmass. This weekend I was booking along with maybe 7 or 8 knots when a big black cloud appeared above us on the lake and I saw a big gust on the water ahead. I bore off to about 60-70 degrees, let off the main (dramatically) and loosened the jib. Wind hit at about 17-18, immediate roll to leeward (heel) followed by responding like a cork under water with the boat flying into and then through the wind. No chance in control at all. My wife screaming from down below how she'll never go sailing again (again ). I'm likely going to move on to my next boat. Got several in mind - - but that's a different thread.

    Rudders and roundup

    Hey everybody - I love the general physics of sailing discussion, but really appreciate the specific comments. I also like seeing the pic of my "Sugar Mountain" (you can't be 20..). I do love her, while she steps on her foot dancing once in a while, serves as a fantastic hotel and swim platform.

    The roller furler is actually very high which gives cruisers better visibility (I am told ). Jib could be in better shape - although I can flatten it out, the leach is starting to develop a permanent curl. Foot is pretty tight with the block in an aft posion.

    Rudders and roundup

    20-30 degrees as measured from my rudder position sensor part of the autopilot. You can see relatively new sails - with the original sails it was virtually impossible to sail upwind at all.

    Rudders and roundup

    This should help understand the position of the rudder - along with my computer measurements to see how much deeper the other rudder is! The rudder is right at the waterline. The hull aft of the rudder is almost board flat.

    Rudders and roundup

    The unbalanced waterline would, I believe, create forces that push the boat to leeward. Longer waterline on the low side - Bernoulli's principles - would create a vacuum there relative to the high side. Whether that imbalance would create a net force toward the stern or bow resulting in a turning moment would be important and dependent on the two waterline shapes (?). First principles.

    This is it - not my hull, but I think the pic is pretty telling... But here's me

    This becomes incredibly more complicated if you are trying to understand the dynamic effect - like the forces and center of effort changes when hit with a gust.

    Rudders and roundup

    Wind changes are prominent with my lake sailing, but when the wind is up we don't see 20 degree wind shifts often. It's the light winds that shift around that much puff to puff.

    Rudders and roundup

    Wow - really great dialog. Thanks all so much. I'm learning quite a bit! I generally sail at 10+ with the traveller full down and a good healthy bubble in the luff. Main out/ carrying a bubble doesn't seem to help much. Maybe the highly loaded leach? I really don't understand why! As does (doesn't?) the first single reef seem to make a dramatic difference. I definitely agree about one-design. When I was ~20 (~40!) years ago I was globally competitive crewing on Solings. Did a summer foredeck crew for Peter Isler at the Olympic Sailing Clinic. I learned SO much - was a much better sailor then. Still, singlehanded sailing for me now is to put the boat in autopilot and continuously experimenting with the sails - as said, "mm adjustments". Usually trying to measure differences with instruments since I don't have a sparring boat, but yes, I also am, however, always looking to "sneak though some chink in the handicap rating system" The comments on the asymmetric waterline while healing also intrigues me. I sail in very variable wind surrounded by mountains. The dynamics of a gust laying the boat over further causing rotation to weather requiring significant helm plays out all the time. In steady winds I can often get control of the boat, but the gusts are often present and associated with roundups.

    Rudders and roundup

    Thanks again everyone. Learned quite a bit. Even got to tolerate insults by someone hiding behind big technical words and without actually offering any suggestions. This MIT PhD in Mechanical Engineering : Fluid Mechanics and Heat Transfer (really) with 55 years of competitive sailing has learned that usually its the smallest people who like to throw around the biggest words. Some comments, like feather to weather, are great, but miss the point that the rudder is going useless. When I can sit on the edge and feather its great - a gust can cause me to lose that edge. I really appreciate the perspective about overall balance and what is needed is to stop the weather helm. Heel and sailplan. Balance the boat. I'm usually singlehanded so weight on the rail isn't much of an option, but I'm going to dramatically reduce main (reef at 10-12; 2 x reef at 13-14 true). I can't shorten my forestay easily (fixed length) but the next step would be to have the yard shorten it. Lastly if that still proves a problem, the 'Fence" seem interesting. I bet I am lifting rudder out of the water and ventilating. Just read a technical paper on ventilation in foils and I think that could well be what's happening when all else is unbalanced forcing a 20+ degree helm.
