RE: [bolger] Re Bolger Snow Leopard
How about a DBD Drive
http://www.dbdmarine.com/dbdmarine.htm
The price is still very high on thse compared to an outdrive, which is a
lot more complex.
HJ
Inboard Installation will be offered,but one of my main aims was to have
shallow draft and an easily beachable craft ,without the worries of
grounding-out on the prop. and stressing-damaging the prop,strut and
shaft.Phil told me he had an idea of how to achieve this(Shoal draft) but
didn't go into much detail apart from comparing it to a "centerboard "type
arrangement with the jet drive unit or propeller and shaft.(Maybe
something like a Dispro boat or that Duck Chalon featured in Wooden Boat
afew issues ago,though I hope its a bit more sophisticated! and strong-VERY
STRONG to cope with the stresses imposed by a V-8 of approx 250-350HP.

Yes ,We will be starting construction(of Snow Leopard- possibly to be named "Arethusa") as soon as humanly possible when the plans are completed,and there's room in the workshop to start.
At the moment my father is about half-way through building a Bolger "Harbinger" 15'0''x7'1'' Cat Boat which should be ready by Nov.-Dec. this year.That should give us some time to get some timber in and season it if necessary.The project to build "Snow Leopard / Arethusa" will be a joint project between myself,my brother and my father(Bruce Tyson) who is a very experienced Boatbuilder,albeit non-professional,and has built approximately 20+Boats, ranging from a 7'9'' Elegant Punt to Bolger's 30' "Romp" design Cat Ketch Ocean Cruiser.
The snow Leopard design has been reduced in size to make trailering and Launch-retrieving a little bit easier.We set the dimensions at 26'0'' x 6'6'' instead of 28'0'' x 7'0'' .Apparently Bolger will offer a number of different propulsion choices with the design,We talked about the feasibility of waterjet drive(Which after some research and consideration, I would opt for, if its feasable,though the "torpedo" stern may make this difficult.)Another option was Outboard power such as a Large 4 stroke,though I'm not sure how this would work without spoiling the general layout and appearence of the boat.Also a conventional Inboard Installation will be offered,but one of my main aims was to have shallow draft and an easily beachable craft ,without the worries of grounding-out on the prop. and stressing-damaging the prop,strut and shaft.Phil told me he had an idea of how to achieve this(Shoal draft) but didn't go into much detail apart from comparing it to a "centerboard "type

Another option which I haven't discussed with Phil Bolger yet is to power the craft with a moderately powerful 80-160HP marine Diesel or marine conversion diesel for a more sedate top speed of around 25-35Kts,instead of the 50-55Kts I first had in mind..Environmentally and in the longrun economically this would prove to be a better option than a large and very thirsty petrol(gasoline) V8,especially if one were able to brew up enough "biodiesel" cheaply..
Even a smallish diesel capable of pushing the hull(which will slice nicely through the chop and clip along at a reasonable pace before planing) to about 20Kts (Top speed) and cruise economically at 15Kts would be an option for someone who isn't in all that much of a hurry to get places,and they'd have a really elegant fast "Launch" in the bargain!.
Hull construction at the moment is to be strip planked-totally fibreglass sheathed and finished as specified in the book-gleaming gloss white with chrome &/or stainless steel trim.
Yes, building the complex shape may be a bit tricky,but we have the experience!
