Re: Where to put small fuel tank on S/D boat

I have strapped a spare tank to the pulpit. Not my area of experience but in hot climates a white sack cover may help. If its swollen before using it lower it on to the water for a while after bleeding off the vapour build up. I now carry two 6 gallon fuel tanks, with quick connects, in the Laz and ...

Re: First mate with hip replacement

At 76 with very active physical life style I had similar concerns prior to a full knee replacement. I solo my 26D. Both before and after my knee replacement I had a great physio, I named tuff love, she hurt. In order to carry on with my life style I had to strengthen all the muscles around the affec...

Re: Physics simulation of a weighted daggerboard mast raiser

I don't have any good way to determine how much pulling force a drogue will provide or how much a spinnaker requires to haul up, but my guess is that the drogue isn't going to be enough without a force multiplier, and then you're talking about a really long line to be storing aboard for that functi...

Re: Physics simulation of a weighted daggerboard mast raiser

So... What's a crow's foot? Haven't found a reasonable definition in Google.
It used to be crows nest then became chicken foot or was it turkey or crow's. Now a camels foot.

All this for the "mast head fitting" with pulleys in and on it plus in this area bird @#$% and bent wind vanes.

Re: Physics simulation of a weighted daggerboard mast raiser

Hi Mastreb Glad to read you are making them think. Don't give them too many clues. Its a stimulating idea. When they made me a mechanic they forgot to do the labotomy much to a few bosses distain. Another project, when you have structured this one. A spinnacker raising cone shaped drogue in the wate...

Re: Physics simulation of a weighted daggerboard mast raiser

PS if there is too much mast movement of the mast put a block and tackle in the system. The hoisting line cannot be lowererd below the fore stay and sail to reduce the traveling distance of the mast. A block and tackle will also give more leverage on a heavy DB

Re: Physics simulation of a weighted daggerboard mast raiser

I'm testing some educational physics simulation software for my Son's class, and, needing something to simulate, I decided to do a weighted daggerboard setup in a connected system with a mast. I tried to post a drawing being, new to this forum I don't know how to. Are you doing your son's home work...

Re: 26X nightmares to avoid

Although I have a 1990 Mac 26D I was surprised the problems I have had to rectify are just about the same as Herschel reported. From shrouds, stays, split ballast tank, engine servicing, rudder and dagger boards braking etc etc. After repairing the ballast tank the other repairs held no fear for me....

Re: Last sail with brand new asymmetrical

water is still 8 degrees Celsius so I am thinking the ballast water should not freeze for a while. Maybe it was a mistake and I will regret it come hauling time in subzero temperatures... Taking the ringdings out in gloves doesn't sound like too much fun.vitger Deckhand Saw a suggestion on another ...

Re: Last sail with brand new asymmetrical

Just joined tonight. Really enjoyed your videos. I now need a bigger bucket for my lists. Got my Mac 26D out of OK lake and covered just hours before the snow covered it. I'm up in Falkland north of you. I solo most of the time but I want a small spinnaker and the one you have fits the need. Saved a...
