Tinker 2 Design Development

by admin on April 12, 2010

Now that I have prepared a preliminary Lines Plan for Tinker 2 the next step will be to produce a small scale, 1:10, hull model. Whilst the 3D facility in Maxsurf allows me to view the hull form from any angle, and is a real aid to Design, actually building a small scale hull model helps to reinforce confidence in the hull form. The Sail Plan is developing and again the emphasis here is on simplicity.

Following are several Images of the faired hull and a Body Plan which will give a good indication of the hull form and I believe reveal a nicely balanced hull. Also attached are my initial thoughts on the Sail plan.

One comment I have received suggested a conventional cabin rather than the Blister style I have chosen and of course this is a personal preference of mine, which I feel will give a safer working platform, but can easily be modified should an owner desire.

As always your comments and thoughts are most welcome.

Tinker 2 a Double Ended Pocket Cruiser

by admin on August 12, 2009

Tinker2a2In the early 1960’s whilst on holiday in Penzance a Knud H Reimer designed Tumlare, Susmar, sailed across Mounts Bay into Penzance Harbour. I have been fascinated by the Design ever since. As one of the crew said to my late father at the time “a beautiful sailing yacht but by hell she is wet”.

Apart from the perfect sheer line and wine glass sections of the Tumlare the balance of the bow and stern plays an important role in the aesthetics of the Design. In fact it is the stern, which many consider to be the most seaworthy of all, that captivates me most of all.

Over the years I have sketched my own version of a small ‘Pocket Cruiser’ with a similar style of stern and wine glass sections, albeit slightly fuller, than the Tumlare.

Tinker 2 is my idea of a small Pocket Cruiser, easily handled and with just the basic accommodation layout in which I have tried to capture some of the Tumlare’s features.

Rather than the small coachroof  of the Tumlare I have opted for a blister deck for ease of construction. With an overall length of 6.7 mtrs and a displacement of around 3000kg the possibility of towing the boat, with a suitable vehicle, opens up the opportunity of visiting new and more distant cruising grounds.

Tinker2b2These are my final sketches of my interpretation and over the coming months as the Design proper is developed I will add details to the site. Once the Lines Plan is complete I will make a small scale model before building a prototype. Construction will either be Strip Plank or Foam Sandwich but this will be a decision I will make over the winter months.
