      Eric, Sorry I did not get back before now.   Yes you are right about the weight of Wolftrap.  Had not really thought that much about it but she weighed 5000 lbs as she was when we first sailed her with500 lbs of ballast. Later we added more and finally as a schooner she must have weighed maybe 6500 lbs. She was build very light with tubing for stringers and almost no frames and using aluminum furniture that was built into the hull.   She was mono coupe construction.  She was intended for Chesapeake bay sailing and we added the ballast to get her a little heavier.  When we first began sailing her she didn't even have a chine in the water.   She was intended to carry a lot of sail for the light air of the Bay here and so was  reefed early.  We sailed her off the wind with main, mizzen, flat spinnaker and a Mizzen stay-sail.  On my Blog "Sailboats Fair and Fine' there are lots of pictures, story and description.  Click this link or copy and paste. I think I mentioned she was slower with the schooner rig and additional Ballast.  This will keep you busy for a while. :-)

      Douglas, you started this thread because you are looking for a wider sharpie hull form than the AS-29. In this ranging discussion you have talked about Wolf Trap. I had not, before you said so, thought of Wolf Trap as a Sharpie. That statement by you created an itch which I scratched by re-reading Phil's description and lines drawing in Different Boats. Itch still not satisfied I searched this list for references to Wolf Trap. Interesting reading, the parts I found most interesting are pasted below. A lot of experience and wisdom. I am incredibly impressed that a thirty foot boat that displaces just 6,000 lbs but could set 800 square feet of sail, 500 square feet of working sail, and keep up with a forty foot boat. I'm impressed that Wolf Trap 30' x 10' weighs just 6000 lbs. My ROGUE is a considerably smaller boat at 26' x 7.5', enginless, I strove for lightness, and ROGUE still displaces about 6000 lbs. I could not find any photos of Wolf Trap. Are there any online? If not, could you post some? I am especially interested to see the schooner rig and compare it to the original. Also, what sort of 8 hour, 12 hour or 24 hour runs did Wolf Trap achieve on various points of sail? Wolf Trap is an extraorninary boat. I'll be very interested to see your criteria for your next boat, and better yet the boat itself, though I would have known more about that had I not missed (until today) your post about how the Trillo boat offers much of what you want, and what sort of rig you would want.


      Re: [bolger] Re: pounding multihull vs pounding monohull?

       I built Phil Bolgers Wolftrap she was a little bit Sharpie a little bit Presto she had about 5 degrees of deadrise amidships and the rudder was fantastic.  WE sailed back from the bahamas to Lake worth Florida in a  North wind of about 18 knots and that against the Gulf stream was enough to raise 6 to 10 ft waves yet we carried full sail.  A friend was anchored inside the inlet and rowed over to talk to us and said "MY GOD Doug, that was the most impressive thing I have ever seen.  You guys coming in, in big seas throwing spray and white water all over the place. Beautiful!
      Wolftrap's rudder had some blade forward of the rudder post and most aft. She had a plate on the top and bottom and one in the middle that stuck out about  for inches on each side.  So with maybe a 8 inches od f rudder in the water when running in big was we never lost steering control.  Even if the rudder cam out the boat had enough direction stability that she would not change direction very much or fats enough that the rudder was not back in the water sooner than needed. The boat had a 10" deep full length shallow keel so the rudder was a little deeper that the average sharpie.  Mr. Bolger did not make any ocean going claims for the boat because she had a really big cockpit but we sailed her more than her share in the Ocean and in some pretty bad conditions though we usually kept her within a couple days of a place to hide should something really bad be coming.   the cockpit size was helped by the transom having an 18x4 inch slot across the bottom to allow water to dump out. On occasion it also dumped in. So you could get a wet foot .  Because the cockpit was wide Phil put a crank Type till that you could pull over and lock in place just above your lap.  Getting in and out of the marina was a tight fit.  My boat was the only sailboat in the marina that could back out of the sliip and turn to port or starboard without jokying back and forth.  If the boat was great then the rudder was pure genious.  Since the centerboard whent up through the deck I built a weighted keel to drop down therough the boat to see how she acted in big seas. This basically turned her into a keel boat it was a fun exercise but did not changer her any, for the better and the keel was never installed used.  One of my old sailing friends stated that she was the best thought out boat he had ever seen.  I had to agree.  The guys at the yacht club called her that fast funny looking boat. They really, really did not  understand her rig or anything else about her. I have had people ask me all these years later what did you ever do with that fast little boat you had. She had developed a reputation.  I stuck out my chest as their is no pride greater than that of having a really great boat.                                                                         Doug

      I had one on my 30ft Wolftrap by Bolger. It had a spinnaker pole that
      rested on on the front of the lower mast with a rounded pies and
      cushioned to front of the mast. The spinnaker pole went forward and the
      end was attached by a line to the end of the bowsprit. This would allow
      me to tighten the luff of the spinnaker in so that the sail could be
      used slightly to windward and was pretty effective that way. She was
      sheeted straight back much as a jib would be. There were to more lines,
      one on each side of the boat much like a jib sheet that by pulling on
      say the starboard side the front of the sail and forward end of the
      spinnaker pole could be hauled to the starboard side. If the main was on
      the port side you were now sailing wing and wing. If you take down
      wind you simply pulled the spinnaker to the part side and jibed the man
      to again run wing on wing on the other tack. On a broad reach the sail
      and spinnaker pole could could be set at any suitable angle. I often
      sailed with main dumping into the spinnaker. Wolf trap carried 500
      square ft of working sail
      in main and mizzen with 300 in the flat spinnaker. The sail was a bit
      of work to get set initially but once set you could carry it up to about
      60 degrees off the wind so there were often sailing trips where we never
      dropped the sail in a weeks sailing down the coast. With a boat that
      weighed less than 7000 lbs and 800 sq ft of sail you can well imagine it
      was exciting.
      In later years we converted Wolf trap to a schooner rig to make her
      a little easier to handle for my wife and I during the Northers that
      blow up in the Bahamian winters. I set the mast and made the main such
      that we could carry the flat spinnaker.above the cockpit. We were back
      up to 800 square feet of sail and it was over the cockpit so I did not
      have to scramble around on the bow. I could sail and set the spinnaker
      at the same time single handing. Four guys in Marsh Harbor wanted to
      know what the hell kind of boat she was when we raced from the West End
      to Marsh Harbor and them sailing a 40 ft boat with them scrambling all
      over her handling sails. The beat us by 9 minuets to cross the end of
      the town dock. There boat was not a racing boat of any kind but then
      neither was ours. I sailed about five miles out of my way because I was
      going to Guana key and had to turn around an go back. My wife thought
      I was crazy but I thought I might have a chance to beat them.
      Any way it's a good sail no mater where you set it.

      Re: [bolger] AS29, LM2, WW and Similar Rudders

      Jon, I had such a rudder on my boat Wolftrap . I sailed her In the
      Chesapeake Bay up to about 6ft short chop quite a few years and only had
      the rudder come out of the water one time. The boat had it's original
      cat yawl rig and was over canvased at my request from Mr. Bolger with
      the idea that I would reef sooner. Well I didn't, so the bottom plate
      was already jacked up within about 8inches of the that plate coming out
      of the water. I changed the rig to schooner later (my favorite rig) and
      I 'm sure the big sail aft tended to drive the stern down some. Because
      the boat had good direction stability she did not change course at all
      when she broke out. If course the rudder was out of the water only seconds.
      The rudder on Wolftrap was aluminum as was the whole boat and had 3
      wings on it one just above water level, one below water at mid level and
      one on the bottom. I sailed back from the Bahamas In what was said to be
      15ft seas. I thought they were less maybe 8-10 ft. WE sailed into Lake
      Worth on a broad reach throwing water all over the place. A good friend
      said we were the most magnificent thing coming in there, he had ever
      seen. Anyway I trusted her helm completely. When backing up under power
      we had none of that thing of her backing to one side. The boat could be
      steered in both directions. I liked being able to climb up the wings to
      get on board. All In all I think it was the best rudder I ever had on a
      boat. Doug

      Wow, good memories. And I'd say close enough for a "You built it"!
      Thanks for the history. Imagine the history behind all of Phil's
      Boats, so much of it we will loose over time.

      Re: [bolger] Re: Work Skiff

      My boat Wolf Trap had a box keel about 8" wide and 8" deep pointed on
      both ends. The width of the keel had a straight run amidships ( no
      taper there) also had a centerboard down through it. It worked fine but
      it took about 400 lbs of ballast just to sink the keel. Seems like a 3"
      wide keel would have carried the ballast the boat need and she could
      have been several hundred pounds or more lighter. I never saw any
      problem in it but just seemed a wast of ballast to me?? Thinking back I
      put more ballast in than was needed anyway which likely didn't do
      anything but slow her. If I had her today I would take some out and I
      advised her present owner to do that. Bolger told me to sail her
      without ballast and then ballast her until she felt good. I put in 1600
      lbs and she felt pretty good. He then told me he was thinking more in
      terms of 800 lb max. Live and learn!

      Doug, It was fun to give some thought to your situation. I think you have reached a good conclusion. Someone posted a link on the Junk Rig group to a Craigs
      Message 123 of 123 , Jun 21, 2012

        It was fun to give some thought to your situation. I think you have reached a good conclusion. Someone posted a link on the Junk Rig group to a Craigs List add for a wooden Colvin designed 36' junk. The boat, now just a hull and diesel in pretty good shape, was selling for half the cost of the cushions I'm having built for my boat. It took me a decade and a lot of money to build as much a boat (and smaller by far) as someone can buy for less than $2000. Buying used or keeping the boat one has is a much better idea than building unless building is the point, or building gets special qualities that are just too important to compromise on.

        Happy sailing. Its been fun talking boats with you. And I'm really glad our conversation lead me to the wisdom contained in some of your earlier posts.
