  1. BRS 15 mk2, # 1

    Travis, It looks quite a bit different from the original. The wide flat on the stem is gone. I wonder if the bottom rocker has been changed? Where was the added beam put in? I expect it will be bit dryer in chop and I hope it will retain the all round utility of the original which I thought was an ideal small skiff. Tom
  2. Chick's Micro Power Cruiser Project.

    Chick, OK, I admit it, I just like a well done flush deck boat and think they look, what is the term? "yar". Beside, I expect to take a ride in your new boat at the messabout. May as well be a boat that looks like I want it to. Get to work. Tempus is figiting.

    Another positive for a raised or flush foredeck is that it adds a lot of righting moment, especially on such a small boat. The raised foredeck on the Mark3 series is a major reason they self-right so easily after a capsize. Its structurally stronger and the strength/weight ratio is better to boot.
  4. Midnight wondering from the Ch. Mate

    In about 1950, the accepted USCG weight for boat calculations was 150 - 155 lbs. Then came the good times, every one started eating the bad stuff, too much of that and the current obesity trend was underway. The USCG is having a hard time keeping up. The number has advanced at least 20 lbs since I started using it as a design factor. I'd use my own judgement for any specific case and the latest USCG number for when that is important.. Cypress is a mixed bag. Heartwood is rot resistant but usually has lots of knots. Sapwood is often clear but not so durable. At first glance, I thought I was looking at "Lapwing" but then saw that it was a Lapwing even though it has my top strake scroll carving and shape. Graham put it in the computer I guess. Very nice anyway.
  5. Outboard flushing

    Speaking of flushing motors, I see the sun shining and there is some hope that this messy winter may be on the wane. LIZ needs to be pulled out of the boathouse, washed outside and de-mildewed inside as well as flushing and cranking the Yamaha. Then there needs to be a launch, gassing up and taking us for a cruise through Core Sound and down to Cape Lookout to see if the Banks and horses are still there.

    Just working on a bit more room for you big feet Chick.

    Chick, 8" plywood will take a scarf and make 15' 6" OAL on this boat so why not go for that?
  8. Chick's Micro Power Cruiser Project.

    Chick, Just for reference, I have built sailboats of the approximate size as the Jessy/Bay River Runner with a class regulation 1/4" bottom. I'm not saying that this is ideal but these Windmills were raced hard for many years without breaking up. They do have a V bottom but the only reinforcement of each side bottom panels was a single stringer which does not add a lot of stiffness. Changing the bottom to 3/8" plus side tank/seats resulted in a structure that is multiple times stronger and stiffer than the thinner ones.. I consider a 1/2" bottom on such a boat way overkill and unnecessarily heavy.
  9. Chick's Micro Power Cruiser Project

    Chick, This is going to be an interesting exercise and I like the idea of doing much of the design yourself. The Bay river Runner or whatever its called now is a good starting point. There is really very little difference between the BRR and the BRS and that is straightening the aft buttock lines to aid planing. For that matter, the original BRS would plane with 8hp and one person. I doubt the 200# target is going to hold for the finished boat though. I also like a bit of V in the bottom for several reasons. Its stronger and stiffer, allows a better pointed bow, more centerline headroom in the cuddy and comes out lighter for the same strength. 3/8" is plenty for the bottom if there is some V but a flat bottom needs to be thicker with a lot more stiffening. Panel span width is all important for stiffness. The layout of AF4 with the slot top is a good one. The flush deck design is lighter, stronger and roomier, regardless of any protests from Oyster. We have found that the enclosed side tank/seat and berth arrangement makes for a very strong and lightweight structure. While the open seat design may look simpler and lighter, it does not work out that way. The tank/seat sides greatly reduce the span of hull bottom and side panels and I think you can get away with a 3/8" bottom and 1/4" everywhere else. I am just starting on finishing the partial Kayak I hauled away from your place a few years ago.

    Beautiful design beautifully built. Now, to what is not so great. She floats down by the stern and way off the design lines. Adding non-functional weight to such a boat is an admission that something is not right somewhere. Like cutting off your toe to get rid of a painful hangnail. Some serious thought needs to be applied about the best course to take in getting to a proper solution. Its clear that there is too much weight (probably about 1000#) cantilevered off the transom and the scant amount of buoyancy afforded by the bracket is inadequate to set it right. Sorry if this is not a popular assessment, but it is what an old curmudgeon sees. As Oyster said, eliminating one engine is the equivalent of an extra 8.5+ cu. ft. of buoyancy in the current stern with two engines. I'd bet the performance will still be just fine.
  11. toilet bowl cleaner to clean hull

    Dollar General sells a toilet bowl cleaner called "The Works" for a dollar or so that must be a close match to the expensive stuff that boating places sell. There are no abrasives and it works well on auto wheel covers as well.
  12.    The Little Known History of Vienna Sausage

    I don't know if it fell behind the shelves or not but I did just lose my lunch. Chick and I already had our discussion of the merits of Southern Sweet Tea while ghosting along on Summer Breeze this afternoon. Its clear that Chick was fed a bottle of undiluted Karo Syrup on his first feeding out of the gate.
  13. Fuel Tanks, Splash well, Windows...

    There's a whole heap of energy tied up in those little boxes. No problem as long as it is let out slowly but, if released suddenly, bad stuff can happen.
  14. This is an interesting topic. I was able to sail on all points and tack readily in BRS Loon in both light and fairly strong wind. I find that Lapwing is not nearly as cooperative but have not tried it enough to be certain of the reason. It may be that the hard chine of Loon provided enough turning moment to aid the rudder and the round hull of Lapwing could not do that. Note to Peter. Sailboat brakes were first introduced in 1926 by Manfred Curry and were just as quickly ruled illegal by the racing authorities. He had a flap on each side of the rudder that could be pulled down into a effective large vertical flat plate which caused all kinds of angst among his competitors.
  15. sail trim

    Yeah Alan, I know that threading the loop can be a bit difficult in strong wind and the reefing lines can help maintain control to some degree. Unless the reefing lines go to a point where the crew does not need to hold on to a banging sprit near the clew end, the advantage is partly washed out. I've only reefed Lapwing once in its lifetime and that was not really necessary as we could have handled the full sail and had more fun. I never ever reefed Loon (the Bay River Skiff). Lapwing has wishbone booms, battens and sail tracks. For most day sailing, I would prefer to go back to laced on sails, no battens and straight sprits. Very little performance is lost and the payback in simplicity, rigging time and effort is a great reward. As the boats get bigger, the extra effort begins to pay off but not nearly as much as some may think. Of course, I'm getting a bit long in the tooth and sailing needs to be simpler or it won't be enjoyed. My fleet is shrinking as one sailboat and one powerboat is being sold and Lapwing is going to Maine to live with son Mark.
