Is there an easy way to calculate ballpark figures of lift and attack angles of planing hulls based on speed, area and weight? I think it is a...
Palmquist's concept: [MEDIA] 16*30's? Paul Scott, what about a quick drawing, to show what you actually have in mind?
Dump the sliding plank and let Smythe´s Synergy inspire you. It is a perfect example of planing amas. It has been covered elsewhere on the...

Love these films! This one from 1977 is also interesting. [MEDIA] As well as this from 1977. [MEDIA]
Made a sketch with a few versions of the trailer application. The first one is with the wheels removed from the beach trolley and the two others...
Reinforced the main beam by adding a 1 m 4" lower tube with 1/8" wall thickness. Added UV-protected surfaces to the Exalite cockpit sidewalls....
Prototyping a beach trolley, but will turn it around with two larger swivelling wheels, 3.00-4/260x85 instead of the tiny 2.50-4, to the rear....
Calculated your ideal beam width and arrived at 15.4 ft, using Tornado waterline length of 5.94m. Ratio is 0.79.
Plenty of knowledge to get here, amongst them how to find the correct beam ratio. Trimaran Design Issues...
How long tubes can you get? I would go for 15-16”. Note the forward beam needs to be placed ca 10-15cm above deck level, right above the center...
Go back to the beams, waterstays and ama dihedral. The other stuff is not that hard to solve.
Google is your friend: nacra 18 square - Google Search...
I guess it is from a 18sq. Buy it if its cheap, be sure to get the battens.
The easy way out is going for 4" as the beam pockets in the amas are 4". I have the same amas but actually use 90mm in the beam pockets with PVC...
2mm will probably work but the waterstays will be critical. I would go for 1/8"or 3mm thickness.
I will update soon. To get more input on Frankentris join my FB-group Frankencats & tris Sverige | Facebook...
At last found a copy of the old rules and they seem to be identical to the later appendix. No exact measures about upper diamond fittings and...
