Title: Sail/Rigging plans for Mobile Marine Schooner
Post by: Netleyned on December 09, 2022, 02:43:13 pm
Looking to build a Schooner/Yacht on Mobile Marines Schooner Hull.
Anyone done one, found rigging plans to suit
Any help appreciated.
Our pond had lost so much water, none of my
yachts can sail so need a shallow draft hull to keep me sailing/sane.

Ooh! Nice hull.


Because there are at least 3 sails on the schooner model, the exact sail plan is not critical, nothing as sensitive as it would be on a bermuda rig. I significantly adapted (freelanced) the sail plan on my schooner model and it still handles fine.
You could easily make a sail plan based on the photo on the Mobile Marine website.

I used Dacron sail material from a sail makers yard and used paper templates that were struck off from my masts and booms (in place).


The rigging plan on my model is also simple. The masts run through a hole in the deck and the thwarts that support the deck. Then stepped into a piece of ply glued above the keel. The mast needs to be slighlty swept back so the keel steep is glued slightly forward of the thwart that it runs through. Note that the thwarts are curved to support a curved deck. It does not have to be a curved deck, but it is better if it is, for drainage. I am sure there are loads of tutorials/builds showing how to do a curved deck.

This soid fixing of the mast supoorts means that the mast stays are mostly aesthetic. There is a forestay, a triasic stay (from mast top to mast top), and side stays that are fixed to pieces of wood glued to the hull, just below the rubbing strake on the hull, just aft of each mast. Because the masts are 'keel stepped' there is very little force on the stays or their mounts.

Two friends and I purchased schooner hulls from Mobile Marine Models in August 2021 and have each made our own design.  After a couple of months of research I decided to adopt a plan that would reflect a typical Grand Banks fishing schooner from around 1880 that has been converted for modern day leisure use.  Schooner design developed over a period of nearly 100 years and no two are alike.  I added a lead keel of about 6ibs weight, then more weight internally to bring it down to the required waterline and trim.  The position and size of masts and sails was determined from three different craft.  My masts are deck stepped so the shrouds are essential. She sails beautifully.
I am unable to upload photos for some reason.  Will try again later

Have now unearthed some of the source material for my schooner design.
1. The American Fishing Schooners 1825 - 1935 by Howard I.Chapelle 1973
2. Essex Shipbuilding by Courtney Ellis Peckham  2002
3. Down to the Sea - The Fishing Schooners of Gloucester by Joseph E.Garland 1983
4. Model Boatbuilding by F.J.Camm  1940

[size=78%]In addition I took mast and sail dimensions from MMM and Nexus plans.[/size]
