A Photo & Discussion Forum for Wharram Design Enthusiasts
This design as described is certainly towards the faster side of choices. This is quite a bit more sail area on a higher aspect rig. For those who prefer a more sedate sailing experience we can build this with a smaller wing sail rig. Personally in my immediate future I am not doing any long trade wind passages in the lower oceans of the world. It is rare when I can take 3-4 weeks off at once. So most of my sailing falls into the coastal category. Still it is very nice to have a boat under you that has inherent seaworthiness in its' design. I still love to sail and pull strings and race and pass boats. I also like the ability to load the boat onto a single truck or into a single container and for a few thousand dollars have my boat in another part of the world. At this point in my life it is easier to come up with the cash to ship my boat to Mazatlan than it is for the time to sail it there. Just sayin, David FAST is FUN
I really like everything about this boat. The idea is a great one and I think your rendition of it is spot on. If I were ordering one it would be a wing sail all the way... Would it be possible to do a double mast? Like a schooner or ketch rig? Would that not balance out with the current beam layout? Or is it just a bad idea? I noticed the old 36's were built like that but those were quite different from what you have here. I don't know... I'm not a boat builder. I like the idea of smaller more manageable sails and just more of them. Also... call me old fashioned but I just love the look of a gaff rigged Wharram. I've raced cats and monos for the past 5 yrs so I understand completely what you are going for.
I don't think your're going to like that square top main when you have to climb up on top of that solid bimini and remove that 45 degree top batten every time you want to put the sail away or completely reef it! This sure isn't the KISS Method in action . . .
Wharram is right! His sleeve sail gives you 95% of the sail area and none of the hassel of raising and lowering a main on a bolt rope or even one with slides.
As for shape, I'm using a modified Hobie mast (semi-wing shape)to start with, then the 18 sq. meter main is going to get a Wharram sleeve sewn on. 22-23% of the cord of the sail seem to be the ideal foil shape on a round mast. Again, Wharram is right; I just had the two Hobie 16 masts to play with and splice together. The Aluminium round tube cost Moe-Knee and I'm cheap!
As for the solid bowsprit, this is a great idea that Derek Kelsall has been using for years (kelsall.com). I've always used 16" as the minimum width for any walkway on a boat. Look at the old Cal 40s (first production open ocean boats that surfed). The Santa Cruz ULDBs all have side deck you can work/walk on. Unfortunately, when I built my 40 Nari in the late 60s is just used netting . . . NOT FUN!
You are right about the batten issue. I thought of this after that drawing. I would use just a big roach main. Taking in / setting sail easily are biggies with me. I like a lot of sail area and don't mind reefing. This 36' could be built any way a body wanted it. We will build a mold that for the hulls that will fall in between the Tiki 8 meter at 26' and the Ariki at 47'. We can provide hulls only all the way to finely fitted yachts of many flavors. The drawing represents some of my thoughts about how I would build this boat for my self. I cruise for week or two at a time in the South FL and Bahamas and do some coastal racing. I would also like a boat I could do some ocean racing in such as the Miami-Nassau, Miami-Jamaica, Tampa to Isla Mujeres. These boats are amazing in what they can in how little water and how comfortable you can be. I will have a boat that it is possible to sail fast and cruise in some of the best places in the world.
