I am looking at a design that has a 0.72/1 ratio between the BWL and BOA. This gives a 25deg. angle of outboard convex flam from the water line...
Remind me, is 20 and 30deg of heel or is 25 and 30deg usually used when calculating basic transverse stability at large angles of heel?
Curious, what factors are taken into consideration when designing the C/L to C/L beam width of a catamaran? How are these factors plugged into...
Are there other important factors besides Center of Lateral Resistance that would influence where to place the Center of Effort ? Are the Centers...
Chris White, in "Cruising Multihulls", suggests that a forward raked daggerboard should slide back up into its case without causing damage when...
I'm interested to hear the opinions of others concerning the advantages and disadvantages of short ama, single beam trimarans. Looking at the...
Can lifting foils benefit a pacific proa's pitch stability and lift its displacement out of the water ? The pacific proa usually has three...
I once had the formula for calculating the BRUCE NUMBER, but now i can't find it. Can you help me out ?
What are the pros and cons of tacking Outriggers for ocean cruising? Say a fifty footer of about 14,000 lbs. displ. Vaka & Ama Intuitively...
Why do some catamarans connect the hulls with arched crossbeams but most use flat crossbeams? Aren't arched beams inherently stronger ?
For small angles of heel it is accurate enough to use the un-heeled metacenter to measure the GM x SINE for GZ, BUT what about 20*-30* angle of...
Can anyone who has owned an Australian built 1969 Columbia 27' with 3200 lbs. of shoal-draft ballast confirm that the ballast is lead?
To calculate the Longitudinal Center of Buoyancy, I: Take the summation of all section areas times their distances from the front of the waterline...
How much does one gallon of epoxy resin usually weigh in pounds or Kg ?
How does the height of a ballasted leeboard's swinging pivot point relative to the boat's VCB effect the GZ ? Especially at 20 deg. and 30 deg....
Are bandsawed resawn veneers GOOD ENOUGH to use in cold-molding, or must the veneers be peeled from rotary peeler machines ? I notice that the...
If not, then only one of the two flat surfaces of each of my quarter sawn WRC logs has to be 6" to fit the height of my band-saw. I would be...
I am unfamiliar with Trimarans, yet i'm curious if the submerged leeward ama acts like a resistance brake-point around which the boat will...
Larson and Eliasson, in the 'Principles of Yacht Design', state that only 50% of a ketch's mizzen sail area is used to locate total center of...
Is there a formula to achieve both an easily driven narrow waterline beam and at the same time prevent excessive pitching in an ocean crossing...
