seaworthy, bigger i-550... suggestions?

Nice work - an amazing similarity to the i550, at least at a superficial level.

Hi Munter,

I hope you mean ""superficial" in a technical manner and not in a social one!

Otherwise you are right. the optics are quite equal, but thats just the fact that the form follows its function. If you want lightweight, high performance, minimum costs and fast construction with the 3 panel plywood hull of a sharpie, your room for individuality is really small. You have to cut everything down to the absolute minimum. From overhangs to structure. Remember that you have to take care of the standart 4'x8' measures of plywood sheets as well.


Everything that is a design issue, really is a independent aspect of this boat. Trim, volume distribution, flow of water around the hull etc.

Dear Jelfiser,

Nice looking boat, no question! But we are talking here about a total different kind of design concept.

strip plank/pvc-wood sandwich rounded hull vs. plywood 3 panel sharpie hull. Do you have just a slight impression what that means in the amount of costs and man hours?

Beware of trailering, all mini 6.50 are near 3m (10 ft) beam. You need an inclined trailer to fit legal width ( http://www.classemini.com/modules/ka.../transport.jpg )

About same size as I 550. Slightly heavier. Stich and glue.

I like your drawing.

I am the owner of the i550 design and have experience enough to not just expand the i550 to a 650, 750, 850, 1100, 2200 et cetera. sometimes it is hard to resist the temptation of what if we...........
It is not simple even if it looks simple. Wind, water and hull shape are complex in relation to each other. I don't know enough yet to design a sailboat.
For the small number of potential builders of any boat I think it necessary to help as much as any of us can to encourage and inform these brave souls of the home workshop.

I agree, when I made my first thoughts about a scale up with the little information I had (no building or lines plan) it was obvious very early that my Costline Flyer will be a total independent project with individual lines.
