The enclosed Bill of Materials will enable you to estimate the cost of materials for the hull as they

apply to your area. To get estimates which reflect the lowest possible price, the following

procedures should be considered:

1. Do NOT merely give the Bill of Materials to your lumberyard and ask for a quotation.

Instead, group members of similar thickness together and purchase boards of proper size

for resawing to the sizes noted on the listing whenever possible.

2. The thicknesses listed for members, unless specifically noted as "NET", refer to standard

lumberyard dimensions BEFORE surfacing. For example, lumber listed as l" material

(commonly referred to as "four quarters" stock) will actually finish from 3/4" to 7/8"

thick when purchased. Lumber listed as 1-1/4" material ( commonly referred to as "five

quarters" stock) will actually finish from 1-1/16" to 1-1/8" thick when purchased, etc.

Specifically state to your lumberyard that thicknesses are to be "standard lumberyardthickness" except for members specifically noted "NET", which then should be finished

to the net size noted.

3. All widths of materials listed are NET or actual width. As noted in # 1, all material should

be grouped for later resawing to the new width whenever possible. An exception to this is

some members of Douglas fir. In this case, due to the grading standards of this material,

the actual finished dimensions will be less for both dimensions. For example, a Douglas

fir member noted, 2" x 4", will actually finish 1-1/2" x 3-1/2", which is acceptable.

4. Select material types which are commonly available in your area. For example, it is

difficult and expensive to purchase white oak in most of the western U.S. Conversely,

Douglas fir and Philippine mahogany may be hard to locate in much of the eastern U.S.

Also, other woods which have been proven in use in similar type boats in the locale canalways be substituted for those materials listed if of similar weight and strength

characteristics. Obviously, we cannot list every type of suitable material available.

5. Some of the lengths listed may not be available in single pieces. In most cases, two

shorter members can be joined either with a scarf joint or butt joint, to form a single

member. Long lengths may be available at a premium, in which case it may be cheaper to

join to shorter members to form a single long member.

6. All plywood should be either MARINE or EXTERIOR grade. The material and glue used

in the manufacture of either grade of Douglas fir plywood is identical. The only

difference is that EXTERIOR plywood may have voids in the inner plys which may be

concealed. In areas where bending will be severe, the EXTERIOR panel may be

substituted for a MARINE panel to cut costs even though the integrity of the panel shouldbe considered.

7. Shop around. Some lumberyards are more adept at merchandising lumber for

boatbuilding than others. You may also find special "close-outs" at favorable prices.

Consider "hidden costs" and "extras" such as shipping and delivery, milling charges,

bundling fees, etc., before purchasing.

Our experience has shown that careful purchasing can amount to a difference of as much as 50%

in the total material cost of the hull.

BUILD IN PLYWOOD

You can build this 25' sloop with a single cabin aft cockpit or with a fore and aft cabin and a center cockpit. The design is available for either plywood (GLEN-L 25) or fiberglass (GLEN-L 25FG) construction. Each is an entirely separate set of plans, al­though the rig is the same in both cases.

. The "25" is easily towed and launched because the centerboard retracts into the hull. The combination centerboard/ballast keel provides positive stability at all sailing angles, plus the ability to enter shoal wa­ters. Handling of the simple masthead sloop rig is an easy job, as all sheets lead to the cockpit.

These popular designs have successfully cruised from the Pacific coast to Hawaii, quite an accomplishment for a boat of its size. One first-time builder entered into competition sailing with exceptional results. His trophies include one for winning first in class in the difficult and prestigious New­port, California to Ensenada, Mexico race .

The GLEN-L 25 is the plywood version, avaHabfe in two cabin styles: the dual cabin DUET and the single cabin SOLO. The hull features semi-round sides and bottom, with a hard chine much less ?tpparent than the typical plywood boat. The roundness of the hull makes it easier to drive, pro­vides easier motion for comfort, and gives better general sailing characteristics.

The DUET features dual cabin privacy and comfortable midship cockpit. The aft cabin features two berths plus private enclosed toilet room. The forward cabin has a com­bination dinette/berth area. The galley is complete with standing headroom when the hatch is up.

The SOLO features a self;bailing aft cock­pit. The spacious cabin has a roomy, en­closed, toilet room plus a 7' long galley area. The dinette seats four and converts to a double berth, while two can sleep in the vee berth forward. Also included is a real hanging locker and lots of storage space.

The rig on either version of tbe GLEN-L 25

is designed for easy handling by the aver­age sailing family. The design is not com­promised by any racing rules and is in­tended for good efficiency coupled with safety and simplicity, not to mention low cost. While the standard set of sails in-• eludes main and jib, or optional Genoa jib, any number of other specialty sails can be

fitted by local sailmakers to suit the owner's desires. The simple masthead rig is not only inexpensive and simple, but can be set up easily and quickly for trailer sailing. Power can be provided by using an optional outboard motor on a transom bracket up to 10 horsepower. Some may desire to install an inboard motor, and this can be done if the unit is very compact, although an off­center angled shaft may be required de­pending on the motor. The inboard installa­tion, however, does add a lot of cost as well as installation complexities over an outboard motor.

Construction of either the GLEN-L 25

"SOLO" or "DUET" is basically similar, both. using- a lightweight but strong bulkhead framed.hull that is easy to build. All lumber specified for building the hull is standard sized readily available and which requires no steam bending. All plywood is 3/8" thickness except for two panels of 3/4" plywood used to build the transom and stem members. No plywood over 12' lengths is required, al­though longer panels may be used option­ally. Plywood planking panels can be joined to form the long lengths with either butt joints or scarf joints. Bronze fastenings are recommended if the boat will remain in salt water, while hot dipped galvanized are rec­ommended for a boat which will not remain in salt water for long periods or will be use_d in fresh water� Fastenings include regular flat head wood screws, ring-type boat nails, and some carriage bolts. The hull is built upsidedown on a building form or "jig" made from suitably sized scrap lumber as detailed in the plans. The instructions (not just a set of "specifications") list all the materials used in the hull plus there is a fastening schedule listing what size fastener to use where, and how far apart. Nothing is left to chance. The instructions go through the construc­tion in a logical sequence starting with fi.rst things first. The plans include all the details for making wood spars, or the builder can elect to use our aluminum spar kit. The ballast keel units, along with the center­board, are heavy units but not difficult to build. These units are fabricated from ordi­nary sheet steel by the builder or any local welding shop. The ballast keel units form cavities which are filled with molten lead. An inexpensive trailer-type winch with posi­tive two-way action is used to raise and lower the centerboard. In short, the GLEN­

L 25 "SOLO" and "DUET" are both de­signed to be well within the realm of most amateur builders, utilizing basic materials and building methods proven in use many

. times over in previous vessels designed by GLEN-L.

The hull form of the GLEN-L 25 "SOLO" and "DUET" is unusual and features what might be called a "soft" hard-chine shape. By careful designing, the sheet plywood plank­ing on the topsides is cut into two longitudi­nal sections thereby allowing much more curvature to the hull form and consequently giving better sailing qualities under all con­ditions. Light air performance is much im­proved over the ordinary hard-chine form, and yet the chine form of the GLEN�L 25

makes the boat stiff in even strong breezes. The convex section formed forward will pre­vent the hull from slamming, while the flat run aft will allow greater speed under way when the wind picks up. With proper atten­tion to detail, and an application of fiber­glass or similar sheathing material and resin over the. hull, you'll be hard pressed to tell the GLEN-L 25 from a factory-produced hull, as the shape of the hull does not feature any of the slab sided characteris­tics common to ordinary plywood hulls.
