Grillabongquixotic

I have been reading the Grillabongquixotic’s blog, and his adventures is mindblowing.
He writes that his Gary Dierkings T2 (slightly larger than plans) weights 200 kgs. He still manages to sail regurlarly at 9 knots and peak at about 12,5 knots. He notices that the Oceanic lateen pushes the bow down a lot, something i hope my flat bottom and greater rocker will counteract. I don’t think 200 kgs is much weight for a 24 foot proa. I hope my proa will weight somewhere around 250 kgs empty.

Cheers

These last three months has been very bad. I have been extremly tired and weak.
I have made some slow progress, and i hope that more light and a warm spring will make me have some more energy. I want to sail the Proa this summer.

I am making the connecting pieces for the akas and a new small ama out of plywood and styrofoam. I hate sanding styrofoam with a beltsander.

Cheers

Purple is soooo 2012!!!

This year NCS S3040-G60Y is very trendy.

I hope the ice melts soon. Its about 18 inch thick where i usually test my models.. The Proa is not icebreaking by nature, so i’m longing for spring.

Cheers

Thanks!

I have to try a slightly asymmetric hull with pointy ends. I believe it will be very efficient upwind. There is a chinerunner along about 1/3 of the leeside.
This is something very close to the 24 foot proa i’m working on.
I want to test the chinerunner, the slight asymmetry and the 12:1 L/B hull before i start cutting out the parts for the large hull. I have learned so much by building and sailing my models. I really recomend testing ideas with models.

Cheers

A picture that show the chinerunner and the slight asymmetry better.

Johannes


(Edit: The wide angle lens makes the windward side have less rocker than the lee-side. The lee-side with the chinerunner has ca 10% less rocker than the wind-side.)

Just a picture of my different models i have made. My first yellow advanced sharpie and the 5 foot long advanced sharpie are missing. I threw them away last summer.

I hope you are feeling better with spring in the air, Johannes. A bit of warmth helps the sap flow better!

The pic with all your test models in a row is really great, thanks for sharing. Now that you are building a new model, perhaps this would be good time to move on from this thread, and create a new one?
