Tech. questions & resin for sale

[mr-fixit]

I am building Chapelle's Hampton Flattie plate 25 in his boatbuilding book as a model. It is 40" long, and the question is should I move the mast aft a little because it is a model an carrys no people? Also I have 16 gals. of polyester resin for someone who is local to Western Pa. I live in Volant Pa. that is 55 miles north of Pittsburgh Pa. Send me an email if interested. I can not ship any of this resin.:)

Can't answer your question about models vs real boats, try a direct message to Donald Branscom who had made a lot of 'em.

As for the resin, the forum rules don't allow us to post stuff for sale -- the "sex web cam" and other threads you see are done by spammers who have snuck on the forum, just once before the moderator axes their accounts.

You're probably better off building to plan and ballasting as needed to make up for the lack of crew weight if you're looking to sail your model. The mast/sail position is calculated with reference to the boats underwater profile, only part of which is governed by fore and aft trim. Messing with mast placement may open a design can of worms that you don't want to get into.

Thanks Mr. Thorne for the reference.
The crew weight would not be a concern unless you were making a actual sailing model of a racing dingy.

The main concern with models is the fact that just about everything can be made to scale and you can pick your "sea" conditions.The only thing not really possible is having wind that is to scale. Since the model would be sailing in scale "hurricane" force winds most of the time you have to alter the mast and rig significantly or increase the depth of the keel.
If you have to alter the rig very much it sort of spoils the looks of the model so usually the keel is made much deeper to compensate.
Look at those plastic radio controlled sailboats that are sold. It gives you an idea how much to add to the keel or you can go by trial and error.

Thank you very much for the replys. I did'nt know about the sale of anything on here. On the model ,I don't know if I should use a centerboard or a fin and bulb. I have used steel centerboards on other models , and they worked very well. They are a little broad of beam, but this one is getting a little narrow. 8" beam @ waterline, 40" overall length. What do you think? It will have about 450 to 500 square inches of sail, and about a 50" mast. One other model I built was to spec. and it has so much lee helm that I cant sail it. That is why I asked about the mast location, should it be moved aft to a point just ahead of the centerboard or fin? And why am I a junior member?
