WILLIAM GARDEN ON TUNNEL STERNS
Paper Presented at the January 12, 1950 Meeting of the Society of Small Craft Designers TUNNEL STERNS William Garden, N.A., M.E. Shallow draft power boats are one of the most interesting and poorly understood problems with which the naval architect is confronted. The design and construction of such a tunnel constitutes a subject which can[.....]
Saving Old Boats
Assessing the significance of a vessel From: Recording Historic Vessels by National Historic Ships, UK. The goal of researching a vessel’s history is to gain a fuller understanding of the significance of: A) The vessel’s uniqueness or typicality in terms of its type and function. Is she a surviving example of a once-common type or[.....]
Scow Schooner hull design
Making a simple cardstock hull model of my 32′ x 11′ cruising scow schooner. Explaining a shape can sometimes be difficult. So I encourage potential builders to make a simple model. Even something very crude teaches all kinds of lessons in how a boat might go together. Having something to hold in your hand is[.....]
Geerd N. Hendal, Yacht Designer
Geerd N. Hendal (1903-1998) yacht designer of Camden , Maine. These drawings were published in The Rudder Magazine of April, 1948. I would guess this was an early proposal to Drayton Cochran for Little Vigilant (launched 1950 to a Walter McInnis design). Geerd was a well known yacht designer at the time but I have[.....]
LEVIATHAN II TSB REPORT
I just finished my first quick read-through of the Leviathan accident report from TSB. Initially I’m totally disappointed. Usually I’m impressed by these reports but I know there is at least one lawsuit underway and this report leaves out (In my mind) some critical information. While the report states that an inclining was done and[.....]
Framing Wooden Hulls With UHMW-PE
Wooden boat building, like all construction methods, continues to evolve with availability of skills and materials. But I have to come down against the wholesale replacement of bent oak ribs with UHMW-PE. As a semi-temporary sister frame repair in isolated cases, the use of UHMW-PE makes perfect sense. It’s easy to install and holds fasteners[.....]
LOOKING AT STABILITY CURVES
Stability information presented to the public is usually simplified to the point of being useless. When I see a published stability curve like that above, my reaction is “That’s nice and it looks good, but it tells me almost nothing.” It’s a nice graphic but key information is missing, mainly data on the conditions under[.....]
BLUENOSE AND COLUMBIA
Bluenose and Columbia raced against each other in only two races in 1923. Bluenose was then 2 years old and Columbia brand new. Bluenose won both those races but the committee awarded the second race to Columbia due to Bluenose rounding a mark improperly. Angus Walters took exception and left Halifax without the issue being[.....]
