1947 wooden Snipe #6715 – Buoyancy Bag Installation

By John D. Rose

I thought you might be interested in seeing the buoyancy bag installation system (forward, side and aft bags) that I am using on my 1947 wooden Snipe #6715. The placement of the side bags will be slightly modified to center them between the diagonal braces for the side decks in the cockpit area.

The work is being done by Tom Regan (Grapeview Point Boat Works, Allyn Washington USA; there is a FaceBook page for this boat shop).

For my next similar installation (on 1966 wooden Snipe #16228), I will use two smaller tubular bags (like the side deck bags) for the port and starboard sides under the aft deck, instead of the larger laterally oriented aft underdeck bag.

The buoyancy bags were purchased from Annapolis Performance Sailing (Annapolis, Maryland USA) – web site http://www.APSLtd.com

These types of buoyancy bags are also used on Optimist Prams, so if ones like I got are not available, substitutes can be found.

Advertised buoyancy capacity of these Holt Allen PVC bags are:

Bow (triangular 33″ x 36″ x 14″)(HASB2101) – 350 lbs

Pillow (tubular side bags 22″ x 9″ diameter)(HASB2202) – 40 lbs each x 4 = 160 lbs

Pillow (tubular aft bag 39″ x 9″) (HASB2402) – 75 lbs

Part numbers are from Annapolis Performance Sailing 2013 catalog (Annapolis, Maryland USA), web site http://www.APSLtd.com . Holt Allen bags are imported into the USA. The bags are secured in place with 1-1/2″ wide white nylon webbing straps and stainless steel webbing plates fastened to the hull or deck structure; these parts are also available from Annapolis Performance Sailing.

The interior of the boat will be spray-painted before the bags and other underdeck hardware items are installed. The paint color chosen for the interior is a special color mix that closely simulates the appearance of varnished cedar planking. The same paint will be used on the exterior of the hull (after the hull is faired with epoxy/phenolic microballoon fairing mix and fiberglassed with 4 oz fiberglass cloth set in epoxy resin).. After these tasks are completed, new 6mm five-ply Meranti marine plywood decking will be installed and covered with 4 oz fiberglass cloth set in epoxy resin; the decking will be varnished. Satin-gloss grade paint will be used for the interior, and gloss grade paint for the exterior.
