    Hey Peter,
    I like your little back deck invention there. Three cheers to Nat for demanding it from your 10 thumbs. I would love to see some pictures of it in its lowered and operational setting.

    Nonsense, I just watched you build a boat with a jig saw, angle grinder, block plane, a couple of chisels and some used sandpaper.

    Hey Chris, you forgot that Peter also used a skil saw to cut the cabinet stock.

    But I must say, following Peter's lead, I used my angle grinder the other day to curve the bottom of the new Teak hatch ring I had made. It worked like a charm!
    Now is a good time!

    Aft deck extension platform continued........

    As we crunched away during the final days at the boat yard, my two remaining neurons had me feeling like I had two hyper-active hamsters,on steroids, going bananas on their circular treadmills. The net result of that craziness going on "up stairs" was a seriously dis-jointed and pathetic photo record of how things went.

    In other words, we jump magically to this:




    The platform is now right side up, the intermediate support beams,seen previously, have been epoxied snd screwed in place underneath and the wonderful Doug B hinge has been dry fitted to the platform. Here we see some QuikFair epoxy about to be mixed and then used to quickly fill the recessed screw holes.




    Quikfair fairing putty is nice stuff to use and really appreciated here as it cures to a sandable state in but a few hours time and does not shrink as it cures. This stuff is a 2 to 1 ratio mix and I just cut some small PVC pipe to measure my amount accurately.One has just to guessestimate how much fairing compound one needs and then cut 2 lengths of PVC pipe,with one lengh exactly half the length of the other.Hopefully the mixed volume will equal what ya needed for the job.





    A few hours later and the Quikfair is sanded flush over the screw holes.Being an epoxy based fairing compound, it is far easier and quicker to sand that straight old fashion thickened epoxy!







    Next up, the Doug B hinge is removed from the platform and the platforms' surface cleaned of dust in preparation for the first of two coats of some high build epoxy primer, seen here during its' induction period inside a closed yogurt container.






    And here she is, after the first coat.I know, this is terribly exciting stuff and hard to take perhaps at this early hour but brace yourselves for just one more.........





    There you go.The last photo of the platform. The next time she is seen she is already installed on the boat. Nat was rather flustered however, at not having had enough time to at least put a coat or two of paint on it but dems da breaks. Lots of time for doing some pretty work once she is hauled back out for the winter!




    Cheers!

    Mr.Greever, I am pleased to inform you that yes, Simon Bates is indeed on board and for once in his miserable plastic bastid life, he is keeping to himself while the rest of us carry on, undisturbed during our small fitting out tasks and moments of exquistite leisure. He has a new friend to play with nowadays and "we" couldn't be happier!

    Ah yes, dear old Pebbles.......Well,ChrisBen, she is in a machine shop waiting for surgery. The problem concerns her inside flange which is too short for the cabin thickness.The solution appeared obvious after asking the question here;http://forum.woodenboat.com/showthre...ghlight=bronze

    However, after several visits to as many machine shops, I'm told the bronze flat bar I bought cannot be rolled and fitted to the existing flange as the bronze flat bar will crack/chip/ and split while it is being rolled to conform to the radius of the porthole flange.


    Only one machine shop has a "solution" which appears to be getting hold of a bronze ring the same diametre as the porthole flange,machining a lip on it and then press fitting it in place. All sounded good until the price for this was discussed.$900.00 CAN.! Some may say,"Hey Tenner, you idjit, that's nuttin' compared to the overall cost of the boat fool!" Indeed, it is small potatoes in the grander scheme of things but I'm having a hard time swallowing the price considering the entire porthole,new, cost me less than $300CAN and that even included shipping from England! Nat suggest buying another porthole,cutting off its' flange and silver brazing the darned thing my self for a savings of near $600. I'm still rolling that idea over in my head while the machine shop owner remains at a loss to clearly explain why I should pay 3 times the price of the entire porthole for a flange extension and I'm even supplying the bronze.


    Were waiting while other stuff carries on happily and hope to have Pebbles in fine form before next summer



    Thanks for asking!



    Cheers!

    P.S. the cockpit has two hand rails(grab rails) just forward of the cabin bulkhead,port and starboard.....

    Speaking of handrails or grabrails, I am wondering if there is a relatively easy or simple method I could use to evaluate my boats' actual stability,as built. I would have liked to ask the boats' designer,but he is no longer available for this earthbound clown.

    I ask this since it has been observed throughout our engine breaking in period,whenever we would encounter wakes from other passing craft, how the boat pitches but hardly rolls as we encounter their wakes from various angles. I know I should not complain about not rolling, but it does feel odd and almost counter intuitive considering this boats narrow wl beam(7'11"),loa of 31' and a draft of 11 inches. Standing on the aft deck,while at the quay, I can get her to roll easily by rocking from side to side yet when underway,she hardly rolls.

    Another thing I've noticed, especially as we near the end of the engine breaking in period and get her running smoothly at her hull speed of aprox. 6.5 knots, is that she leans outward in a turn whenever we put the helm over too quickly.

    Never having owned a power boat before and certainly nothing this size, leaves me like a new born pup at the races.I haven't a clue what is "normal" or not.

    Any thoughts, suggestions or ideas appreciated as always!

    Cheers!

    Hi Cam,

    No invention of mine but rather an option presented on the plans. We hope to get some "operational" pics of it before the boating season is over up here. I'll second your three cheers to Nat.....she drove the whole operation with a firm hand and a warm whip! Were it not for her, I would still be plodding along happily guzzling beer in the bowshed and taking pictures of how I screwed and glued stuff together. I'm much happier with the boat in the water! Trust me!!



    Cheers!

    Try this:
    Knowing the boat's natural roll period is an excellent indication of its stability, and there are several rules of thumb we can use to evaluate roll period. In general an acceptable, but minimum, natural roll period (seconds) should be equal to a vessels maximum waterline beam in yards. For example a boat with a 30-foot beam should have a roll period of 10 seconds (30 feet/3 feet per yard = 10 yards or 10 seconds). Cruise ships with beams of 100 feet have roll periods of approximately 30 seconds (100 feet/3 feet per yard = 33 yards or 33 seconds). Additionally, a vessel's natural roll period may be calculated using this formula:Natural Roll Period = (.44 x Vessel’s Beam)/ Square Root of GM
    GM is the distance between the vessel's center of gravity (CG) and the metacenter (M), where metacenter is defined as the point through which the center of buoyancy acts when a vessel heels.
    You can get her rolling by moving your weight back and forth across your cockpit. Then count and time 10, 20, or any easily divisible number of rolls (port to starboard and back is one roll). Do the sums and you have a measure of stability or as we "waste of times" call it GM. I'd be interested to see what you get.
    It really is quite difficult to build an ugly wooden boat.

    No, there isn't....The designer could not tell you what the real, as built, stability is unless he or she measures the floatation and performs a inclining experiment. This information is plugged into a computer program (we used to do it by hand) to calculate righting arms at various heel angles. Designer's calculate preliminary stability based on some guess/calculation as to where VCG is and the finished boat's weight and trim, in reality it's always different. Specific weight (density) of materials has a lot to do with this, weight of wood varies with moisture content, glass sheathing weight varies with resin content, how much filler was used, how much was sanded off.....and on and on.......

    I'm not sure what good knowing your stability (in reality it would be the range of positive stability) will do you. As long as you (and I know you are wise enough to do this) avoid the perfect storm and don't run in the trough of monster surf, you'll be fine. Scientific curiosity is another thing and I would be happy to work through a stability project with you (for the edification of all reading this, not as a commercial enterprise). Suffice to say that your boat is initially stiff but also has a low angle of ultimate stability.

    I ask this since it has been observed throughout our engine breaking in period,whenever we would encounter wakes from other passing craft, how the boat pitches but hardly rolls as we encounter their wakes from various angles. I know I should not complain about not rolling, but it does feel odd and almost counter intuitive considering this boats narrow wl beam(7'11"),loa of 31' and a draft of 11 inches. Standing on the aft deck,while at the quay, I can get her to roll easily by rocking from side to side yet when underway,she hardly rolls.

    Another thing I've noticed, especially as we near the end of the engine breaking in period and get her running smoothly at her hull speed of aprox. 6.5 knots, is that she leans outward in a turn whenever we put the helm over too quickly.
    The lack of rolling was the designer's intention and indicates high initial stability. If you do Perie's rolling test you will find your roll period is very short. This is typical of flat bottomed boats and is nothing to worry about....it also indicates a vessel not intended for a North Atlantic crossing in winter.....

    The outward heeling in turns can be disconcerting for those used to vee bottoms that usually heel inward in a turn. As long as the heel is no more than 8-10 degrees I would not worry......Obviously it could be a problem if it was exaggerated by...say 20 passengers on the roof all running to the low side as you turned that way....the boat might indeed roll over....this is why we look at this sort of situation very carefully for passenger vessels......If you install an inclinometer close to the helm make a note of the heel angle in a turn and let me know what it is. It should vary with speed.

    Seeing how the last pictures delt fleetingly with an item destined to hang forever off the transom, how nice to come across a few pictures taken of an item destined to sit forever at the opposite end of the boat.A Samson post or mooring bit. Strange how an item easily done eons ago became forgotten until virtually the last minute.Surely the first warning signal of a disorganized and scattered mind!






    Here we see four pieces of sugar maple,7/8th" X 3 1/2" X 38" found laying around inside the bowshed and just on the verge of getting pre-wetted with some epoxy.






    And here are those same four pieces of Lombardi popular now with the six faying surfaces liberally soaked with clear epoxy ,prior to the application of the thickened epoxy.






    And voila!, the once four seperated bits of Ponderosa pine snugged up nicely in the thickened epoxy mixture.






    There is nothing like the sight of thickened epoxy squeezing out along every seam and joint to make a fella feel smug and manly about his mastery of laminating.
































    Nor too is there anything like the sight of seeing ones gf labouring up in the "heat zone" of the bowshed, on hands and knees, correcting and fussing over the finish, to make a fella feel cheap,lazy and mighty thirsty!

    Hi Nick,

    Thank you for your suggestion! I'll give it a go in a few hours time when I am back on the boat. Just to be sure I understand this correctly: I am to get the boat rolling by rocking it side to side from the cockpit.Do I have to maintain this rolling while timing each roll or do I simply time each roll as they decay and the rolling completely stops? How deep of a roll should I induce or does this matter? Finally, say after 20 self induced rolls, with each roll period timed, am I to add these times together and divide it by? or do I just figure out the average for the 20 rolls?

    Thanks once again for dropping by and sharing your knowledge.



    Cheers!

    Interesting link Daniel but it appears to apply to vessels over 24M in length and not some fancy over-blown skiff like I have. I'll see if I can make out what it wants me to do, after I've gone through the exercise suggested by Nick.

    Merci beaucoup again and just the same!

Designer's calculate preliminary stability based on some guess/calculation as to where VCG is and the finished boat's weight and trim, in reality it's always different. Specific weight (density) of materials has a lot to do with this, weight of wood varies with moisture content, glass sheathing weight varies with resin content, how much filler was used, how much was sanded off.....and on and on.......

    I'm not sure what good knowing your stability (in reality it would be the range of positive stability) will do you. As long as you (and I know you are wise enough to do this) avoid the perfect storm and don't run in the trough of monster surf, you'll be fine. Scientific curiosity is another thing and I would be happy to work through a stability project with you (for the edification of all reading this, not as a commercial enterprise). Suffice to say that your boat is initially stiff but also has a low angle of ultimate stability.



    The lack of rolling was the designer's intention and indicates high initial stability. If you do Perie's rolling test you will find your roll period is very short. This is typical of flat bottomed boats and is nothing to worry about....it also indicates a vessel not intended for a North Atlantic crossing in winter.....

    The outward heeling in turns can be disconcerting for those used to vee bottoms that usually heel inward in a turn. As long as the heel is no more than 8-10 degrees I would not worry......Obviously it could be a problem if it was exaggerated by...say 20 passengers on the roof all running to the low side as you turned that way....the boat might indeed roll over....this is why we look at this sort of situation very carefully for passenger vessels......If you install an inclinometer close to the helm make a note of the heel angle in a turn and let me know what it is. It should vary with speed.

    Well Mr.Roberts, that is some very nice and detailed information and very comforting, especially the explaination of the outside healing during turns. Also,harbouring no wild desires to run the boat in either the North Atlantic or a perfect storm, it is good to know the boat will punish me seriously if I ever become so reckless. I will have deserved it!

    I'll pick up an inclinometer today and see what readings I get over the next day or two when I go out.

    Finally, I'm somewhat bowled over by your generous offer to run a stability project for this boat.I would be honoured to give it a go and only hope I can properly understand what you will be requiring of me to provide in terms of raw and running data. I suspect that many others too would be intrigued by the project as it may illuminate and/or disipate some prejudices regarding flat bottomed boats in general and Bolger Boxes in particular.


    Respectfully,

    How to conduct a proper "Inclining Experiment!"











    This is actually a full roll over test (self-righting). I believe they're conducted on all of the 47 footers that are built. You can't see it in these pics but there's a big 360 deg dial mounted on the transom. The blue barrels carry ballast equivalent to a fully manned cutter.

    I dont think my boat would make it through that test.

    Wow, 5000+ posts! I have enjoyed all 5,000 (well, almost all). I confess part of me wanted the build to take longer so we could be looking at 10,000 posts. Part of that is selfish, though, because I might have had another long-shot chance or two at a Laughing Polar Bear cap.

    Congratulations, Peter, on a fine build!

    Stability test: Set an un-opened beer (if you can find one) on the table, and proceed to try to knock it over by making to boat roll. Ballast the boat with more Beer until stable enough not to knock over your beer.

    This is a LPBC BS101 certification.
    There's the plan, then there's what actually happens.

    Knotty,

    The test above being done on the CG cutter is not an "inclining experiment", it is an inversion test done with a crane to demonstrate the vessel's self-righting ability. Peter's boat is not designed to be self-righting from 180 degree inversion and would not be tortured in this manner.

    On the other hand Peter's boat is intended to be self-righting from some smaller heel angle, with some work and calculations we can establish exactly what that angle might be.

    An inclining is not dramatic. It involves heeling the boat no more than 3 degrees using a known weight (called a inclining weight) positioned a known distance from the centerline. Using the heel angle created, the weight of the boat, and the waterplane area (a cut through the boat at the waterline) calculated by computer allows us to find the vertical center of gravity (VCG). VCG is required to establish righting arms for each angle of heel and thus create a curve of righting arms. Explaining all this will require starting at the basics so there will be a number of posts involved. One of the first things I need is a hull lines drawing to make the 3D model from, I see I have a profile and arrangement drawing for the boat but if a section lines drawing exists it would help.

    TR:
    I believe Bruce Hallman can provide you with the 3D form if we can round him up. He has an extensive library of Phil Bolger designs in 3D wire frame illustrations.

    I believe it's best to be prepared for a worst case scenario! Turtle's have been known to flip over spontaneously ya know?

    Here we see four pieces of sugar maple,7/8th" X 3 1/2" X 38" found laying around inside the bowshed and just on the verge of getting pre-wetted with some epoxy.






    And here are those same four pieces of Lombardi popular now with the six faying surfaces liberally soaked with clear epoxy ,prior to the application of the thickened epoxy.






    And voila!, the once four seperated bits of Ponderosa pine snugged up nicely in the thickened epoxy mixture.






    There is nothing like the sight of thickened epoxy squeezing out along every seam and joint to make a fella feel smug and manly about his mastery of laminating.
































    Nor too is there anything like the sight of seeing ones gf labouring up in the "heat zone" of the bowshed, on hands and knees, correcting and fussing over the finish, to make a fella feel cheap,lazy and mighty thirsty!



    Cheers!

    Last minute? Like, "Man she looks great floating there, now back that crane away. Here, take this line and take a turn around the....... OH $hit!" kind of last minute?
