MYYOT launched

[waynemunro]

The sails are made from an old Jib or Genoa (can't remember which) froma Farr 38. It was given to me as it was about to be burnt due to delamination. I managed to cut both the main and the jib from the bottom part of the sail, and luckily one of the corners was almost the right angle for the inside corner of the main, which saved me sewing two sides of that sail.

The sail pattern is of course from the original sail, so is probably completely inappropriatte for the weekender sail.. but for the price I reckon it should be ok (and I actually quite like the look)

Wayne, I, too, noticed and liked the pattern made by the seams of the sail. Looks like you've started a new style. Well done all around. 8)

The style of sail cut is called

"biradial" IAW Henderson's handbook "Understanding Rigs and Rigging". Does look kinda neat. Wonder what advantage it gives.

the sails do look good but the knockdown pic is pretty scary. is the water cold? is this pretty indicative of this design that she knocks down without rounding up into the wind? were you able to self rescue or was outside help necessary. thanks, Bill

[waynemunro]

yeah Bill, I can safely say that the water was very cold I think it was more that the air temperature was cold though.. so there was no warming up once out of the water.

I had chosen the location for its shallowness, self rescue was trivial as the water was only up to my chest, just basically standing on the bottom and pushing back up again (pushed on mast and shrouds). There was little water inside as it had floated high enough on its side that the level did not come up to the hatch opening. Note that I suspect that had the water been deeper itwould have turned further over (didn't turn due to mast hitting bottom).

Please do not take this as any condemnation on the weekender design, I simply don't know what I was doing, and the winds were bad for it.

I have just come back from my second sail, which was much better though still had its moments. I spent the first couple of hours in very light winds doing between 0.5 and 3 knots across the harbour... and had just decided to look for a place to beach up and have a waterski with somefirends that were there in a power boat when a hug wind change came though, the wind almost instantly went from peaking at I guess around 5 knots to averaging about 20-25.. very scary I managed to drop the main, and sailed bck across the harbour on just he jib.. doing over 3 knots all the way (GPS). Had my friends in the power bot riding shotgun just in case but we made t back without incident and got the boat back on the trailer.. evreyone still dry.. phew...

there should be some pictures from that.. hopefully get them on later.

Also, thanks Arnie for a name for my sail cut.. though it is completely unintentional that it resembles any proper cut. It is just the luff end (?) of the sail that I cut mine from

yes, the learning curve is quick after you have felt that cold water a time or two. not a lot you can do about a large gust like that if you are not on the mainsheet quickly. I really knocked a macgregor 21 down sailing by myself when I first started sailing. took forever for her to come back up with the mainsail full of water, but she did and the cockpit drain did the rest.

has anyone ever knocked a wkender down in deeper water and self rescued it? I just want to know for I am getting the urge to build something again. thanks for the reply. Bill

OK Wayne, how's abouts a report on the motor mount? Have you figured it all out to make a report? Inquiring minds want to know!

[waynemunro]

ok, capt Jake.. I have been out for a second time now, also cut short due to radical wind changes, but did do more time with the motor up and down .

general opinion is:

- strength, slop, etc... not a problem, mount is all I would expect, there are a few mm of lateral movement, just due to the nylock nuts not being done up tight so as not to have too much friction, but this is only noticeable when standing at the back of the trailer and wobbling the mount. Not at all noticeable when using motor in practise.

- raising and lowering, lowering is no problem, I probably need to scratch on an arrow to tell me which way to move the lever to release it, but that is a small issue. raising probably needs a little more practice, and maybe a handle on the centre lever of the mount, is not too bad though.

- height of the motor in the water. I have found that in the mounts raised position, with the motor tilted down it is still fine for use in calm water, the cavitation plate is above the bottom of the transom level, but that doesn't seem to matter as the motor is back far enough (does about 4 knots at full noise with 3hp, I think). When the waves were a bit more significant the motor did leave the water a bit in this position occasionaly. With the mount int he lower position, and the motor down it worked well in all conditions, though when going full noise the mounting plate did collect a lot of water as the bottom edge of it was just uder the surface. If I were re-designing I would make this plate smaller, as the motor only attaches to the top portion anyway.

- when the motor is wanted out of the way, the mount performed well, it was raised well clear of the transom, possibly a bit too clear actually, initial caluclations were based ont he mount being mounted vertically, as it was eventually mounted flush with the transom the effective rise of the mount was higher than anticipated. I am a little worried that it might even be heigh enough and forward enough to possibly tangle with the mainsheet on a tack, though this has not happened yet. If this is the case I may put in a second notch to allow a secondary 'raised' position.

on the whole I am very happy with it, great for a prototype... if rebuilding I would probably make the whole assembly less deep, which would mean either using flat ali of a lesser width, or re-arranging so that the upper and lower arms can overlap at acute angles (I'd probably do the latter, as I like the large pieces of ali).

I'll see if I can drag up a couple of pictures of it on the boat that day.

ok, here are a couple of shots:

Thanks Wayne, now to find your original posts to review it once again.

thanks again it looks wonderful.
