mast info needed for Grumman 8' Dinghy

[GordonHawk]

Back intheearly 70's I went to the Marathon,NY boat yard where theymade the Grumman 8' Dinghy..dsigned I believe by Phillip Rhodes.. A few decades ago my mast was stolen.. for aluminum most likely.. I'd like to sail again.. but I can scarcely remember how it was rigged.. I need a mast height / layout... and perhaps boom info for this boat.. I've contacted a person in Marathon .. and he said there was no info there.. and he had never seen one... the company was sold a few times he said and each came in and took away what they wished.. I've contacted a big CT mast firm and they said they had no mast info on this boat.. I'm at a loss as to what to replace the old one with.. and what the new one might look like... I have the sail.. it is about 12' tall.. is there someone with an old brochure.. an old mast... the tracing of the mast hole in the front seat looks to have it be a 2"x2 1/4 " SECTION...Thanks ..Gordon

It might be hard to find any original drawings or photos. The rigging for dinghies is pretty basic. If you can post pictures of the boat and the sail, we might be able to tell you what you need and how to set it up.

I believe that I have original literature on the Grumman dinghy. I had considered buying one for my first boat. As I recall Grumman made both an Aluminum Dinghy and also later marketed a glass one made by Pearson I believe. Is your boat glass or aluminum? If I have the literature and you send me your email address I should be able to scan and email you a copy or what I have.

Gordon,
If you have the sail why not sit in the boat and have someone measure how high the boom needs to be if it’s going to clear your head and then call Dwyer Aluminum Mast Co in CN and talk to them. You will know the height because the sails leach plus the clearance for the boom height is known and you know the size of the hole in the seat for the mast. You also know how long the boom needs to be because you know the length of the foot so don’t you have everything you need to figure this out? Dwyer can tell you how much you need to add for the clearance at the top and the end of the boom.
All the best,
Robert Gainer

Thanks Jeff.. looking foward to seeing the info

YesRobert...I was about to makeit up.. I'd called Dwyer ..and was suprised to hear they didn't have mast info on just anything that was made in production.. .. I can about figure everything you mentioned .. I don't think there was full clearance below the boom for those seated... it's been 25 years or better since it has felt sail..
Phillip Rhodes did a grand bit of work designing this dinghy and I would like to start any improvments with his great base.. thanks for the help... when I get a good design.. I'll surely be calling Dwyer again... to make it up for me..
