    On my side of the pond coiling a line is referred to as โ€œ fakingโ€ the line. Some refer to it as โ€œflakingโ€ but I believe faking is the original term. In fact the terms are used interchangeably. Makes for a good discussion over an adult beverage! ๐Ÿ˜Ž

    Alessandro, for coils of larger diameter โ€œropeโ€ you can tie them the same as you do with real rope. But for the most part I too use cya. You have to use VERY SMALL drops however. Otherwise they will be stiff & hang incorrectly. Yours are Bella!

    You might consider just sistering a short length of wood on both sides of the keel that overlaps the break. Not true to type but a straightforward repair thatโ€™s below the waterline so wonโ€™t be all that noticeable.

    Excellent comments all. I would add an understanding & supportive wife to the top of Alessandroโ€™s tool list. Disclaimer, Iโ€™m not in anyway suggesting oneโ€™s wife is a tool, only that her support is at the top of any list.
    Mike Sโ€™s comment about tidying up after oneโ€™s passing is what concerns my wife; a valid issue. Each of my two sons & three grandsons gets a boat. My only granddaughter gets the sailorโ€™s valentines Iโ€™ve crafted. Flash! Next boat will be named after my granddaughter & designated for her! Six boats accounted for is a rather small part of my fleet. Thatโ€™s why I am attempting to sell/donate one when I start a new one. Admittedly I am falling behind in the sell/donate portion. So, I also am always interested in what others are doing.

    After seeing more of the photos you have posted I can see that it clearly is a planing hull. Should have picked up on that beforeโ€ฆ.duuh! Guess I was looking at the cabin arrangement topside & assuming it was the typical displacement/semi displacement hull found on cruisers.BTW, I can see your after keel surgery pic that the current rudder needs to remain as is.
    Thank you for posting all your efforts & experimentation in this thread.
    Itโ€™s been a good ride indeed!

    Cash, sorry for causing you grief with the nav lighting. However your solution looks like โ€œas designedโ€. Well done.
    You donโ€™t seem the least bit concerned that you havenโ€™t splashed her until completion. Thatโ€™s interesting since Iโ€™m sweating that I havenโ€™t had the Wasque 26 in the water as yet & the major build steps are complete. Everyone has their own build sequence; no right or wrong way.
    Looking forward to the maiden video.

    You can really get into the weeds of fluid dynamics if you do a web search like โ€œprop/keel interactionsโ€. I found this reference that is non-mathematical & should adequately serve our model building needs. Itโ€™s a bit disappointing that they didnโ€™t go into a deeper discussion when they described interaction between a deep keel & two bladed prop & dive into a bit of fluid dynamics. Iโ€™ll continue to look for something along those lines.
    And now to include the reference.

    Hooray!๐Ÿ‘ That looks great Bob. Iโ€™m glad it runs completely counter to what I thought it would! The wake looks the way it should; flat behind the stern, bow wave prox halfway down the side. Now I will have to try to understand the prop/keel interaction.๐Ÿค” Did I completely miss something? Was the hull rolling to port when you were doing a turn to Stbโ€™d & vice versa?
    Well on you; problem solved!

    โ€œTrouble is with models is that they can be easily over powered/ motored and therefore driven at higher than scale speeds and also asked to do sharp manoeuvres in water conditions that a full-sized boat wouldn't do or be able to do! Or even the crew being able to withstand! Folks soon get bored with tootling around unless it is a model obviously designed for slow speed, like a tug or river/pleasure craft and the temptation is to give it some beans!

    It's made for an interesting discussion though and exercised our brain cells and it will be interesting to see what, if any, difference results from Bob removing the keel.โ€

    Chris,
    It certainly has made for a brain exercising experience. Iโ€™ve learned a lot & itโ€™s caused me to recall some things I had forgotten.
    I completely agree with your comment regarding overpowering & wanting to go faster. My sense is that is an issue for Bob. The only place I have seen a wave deflector is on model warships. Warships may encounter mountainous seas!
    The keel reduction will be interesting to me. My sense is that it will make matters worse. The keel is intended to improve tracking & turning stability particularly for round bilge hulls. But from the discussions herein it seems to have worked for others.
    My builds are all scale in nature. So for me making the model as true to type in appearance & performance is the goal. I generally have to slow mine down. If Iโ€™m honest I enjoy building more than running.
    Bob; we anxiously await your keel trial.

    Chris, Iโ€™m an engineer, not a naval architect but those principles are physics-based & apply to all hulls, sail & power. Their individual impacts may vary depending on the hull form& function.
    Of course I could be misguided but from pics Iโ€™ve seen the SC hull to me defines the shape of a displacement hull. Hull forms of the displacement type Iโ€™ve viewed, 1:1 & model include variations of the extensive keel. Added to that is the SC appears to be designed as a cruiser. 1:1 cruisers do not plane since that is not their function. Iโ€™ve never seen an overturned SC so maybe the hull is a hybrid between a displacement & planing hull.

    Of course I could be all wet!๐Ÿ˜€๐Ÿ˜€

    Bob, in a nutshell, hull speed is the max speed the hull can run before handling issues occur. Adding power after hull speed has been obtained only forces the hullโ€™s stern down. I realize that your vids are at a higher speed than you normally run and yourโ€™s squats in your latest one.
    Glynn Guestsโ€™'article & subsequent site comments are talking about stability. The old adage of keeping things above the deck light is a great rule to follow.
    So, there you are. Factors creating your issue include prop torque, hull speed, stability, prop speed & pitch, type of hull, weight distribution, etc. etc. ๐Ÿค”๐Ÿค”

    Bob, some additional reading material while you are traveling. Iโ€™m sure you have either timed or calculated how fast the Kommander is traveling. Is it beyond hull speed? How doors it compare to the real boatโ€™s cruising speed?

    Thank you Cash. I used Elmerโ€™s which was impossible to peal off the frames. Do you know if the glue you referenced is still on the market.?
    Even though I glued the frame drawings to the ply I have to be a LOT more careful cutting them out. I thought I was being precise but not.
    For next scratch build I will probably contract for laser cutting.

    Chris I think you
    added a lot when you talk about the full length keel. So, the speed of the prop, the driveshaft angle relative to the bottom of the hull, & the keel all contribute to the issue facing Bob. Adding Bobโ€™s comment about the shape of the bow to the above reinforces my sense that the hull configuration wonโ€™t support very high speeds.

    Chris, that makes two of us with hurting heads. If the boat actually dives under the first wave as I believe Bob has indicated, the short period of the waves allows no time for the hull to regain any buoyancy before it encounters 2nd & succeeding waves. Things go downhill (get wetter) from there!
