[q] scaling down a whaleboat
Hi all,
Whaleboats have amazing lines, don't they, but are also 24-28 ft long and certainly no cartoppers. One could (naively) think of just getting the plans for a whaleboat, scale all dimensions down by half, choose lapstrake construction, symmetrize the oars positions, discard a couple of seats together with some whaling implements, and there you have a mini-whaleboat for two people. But then, on second thought, maybe not all the dimensions should be scaled down linearly, just by half, and a more refined approach should be used for the various parts of the boat and rigging. So... 1) what is the correct procedure to scale a boat down ? 2) where can I find plans for a whaleboat ? Roberto |

[q] scaling down a whaleboat
You mean the Montague whaler the navy used to use? If so there`s some info
in old copies of "The Admiralty Manual of Seamanship" (British Admiralty, that is). My copy containing info. was from around 1934, I don`t know when it became obselete and was dropped from the book. As you say, great lines- guess a naval museum could help? Dunno if they could be scaled down directly though, the beam IIRC was 7 ft something..... Good luck.

snip whaleboat scaling question Would it not be simpler to find plans for a peapod? ;-) Steve |

[q] scaling down a whaleboat
Roberto,
There are several types of boats refered to as whaleboats. I assume you mean the small boats used by New England Whalers for taking off a ship and harpooning a whale. I have thought about doing just this thing but after doing a little research I find that not all whale boats are alike. You may be able to get lines plans for a whaleboat at the Mystic Seaport Museum in Connecticut. I have a photo of a boat they have there if you would like to see it. Otherwise, the boat you are describing sounds an awful lot like a St. Lawrence Skiff. I have plans for one of these and I believe this boat is about as close as I've seen to a scaled down whaleboat. The boat I have plans for (Annie)has a waterline that is wider at the center than a whaleboat would be (proportional to the size).The bottom is flatter. I think this might be a good thing in a small boat. But apparently others did not think so and there have been other boats designed that use a very narrow bottom width such as the Adirondack Guideboat that may have been derived from a whaleboat. This photo is an early Adirondack Guideboat and they were subsequently much refined. http://www.geocities.com/new_old_boa.../index/gb5.jpg Here are the refined versions http://www.geocities.com/new_old_boa...dex/gboats.htm If you decide to build one of these let me know and I will be happy to offer info. I built one last year using the strip method and it works great. BIANCO ROBERTO wrote: Hi all, Whaleboats have amazing lines, don't they, but are also 24-28 ft long and certainly no cartoppers.
