Whether its polyester or epoxy, the weights vary between products. Most resins fall in the range of 1.10 to 1.22 specific gravity or 9.2 to 10.2...
And then what? Do you stay moored by the stern or drag everything to the bow? Easier to pick the ball up at the bow in the first place.
I do engineering for various designers and I've been using SolidWorks since 1998 and have worked with many users of other software. SW has...
I think most people are assuming a lifting sling where it may be one where you pull the boat onto cradle or longitudinal bunkers and the whole...
The boat was a 24 foot one-off that I designed and built for myself. Mast was a 5 inch diameter light pole and I used to pull the boat down with...
Eric, I appreciate that most of the time, the upwind righting moment is all you need to consider, but.......... I lost the main mast on my...
For unstayed masts, you really need to consider the moment of the boat going downwind and stuffing the bow under in the rig design, not just the...
A lot of the examples shown are flush deck, but not raised deck like the CAL example. The flush deck is feasible when you have heavy displacement...
You have to think of how the boat is used. The situation I think about most is the crew that is trying to sail high and carry the sail to a...
Just remember, you are engineering for the peak load which you will only see on rare occasions. The rule of thumb was derived for heavier boats...
I would say that the working load stated for the block was probably based on distortion of the bearings rather than breaking load of the block. So...
I know this sounds simplistic, but I have never had a sail maker give me a better number and I have never had a sprit break when designing to...
I have been using HullScant for almost 2 years now and echo Alik's response. Relatively easy to use. I added the rudder module as soon as it was...
I've read the reports on this boat along with several other reports on keel failures. Dobroth raises some good points and then looses credibility...
I think you have to see the shapes in your mind, whether you are putting it on paper or into a computer model. If you can't do that, or if you...
