I understand the difference with RAIDing too - so talking about a bit more.

Hello MIK

Anything that I need to pay special attention to when fitting toestraps?

Your flickr rigging guide for the PDR's shows some ideas:

Would a similar system (toestraps in V) work for the GIS? And if so, at what width should I attach saddles to attach the toe straps to at the mid frame to enable easy hiking just aft of the mid seat?

Should I bolt the saddles through the bulkheads at lower frame height with some ply backing and stainless steel spacers ?

Thanks!

Best regards, Joost

While the boat shown in the link below is nothing like a raid style of boat I thought there may be some interest in the design that got me thinking about a lightweight speed machine that would interest Raiders.

Miks designs I think have similarities to the sharpie design elements, hope you don't mind me saying that Mik.

The cartoon above represents exactly the line of thinking I was following so it will be of interest to me if anyone sees potential for this style in a multi purpose format that includes Raiding.

Cheers

Hello Mike,

I love the lines of this boat as a light weight sailing speed machine.

I am however not convinced this design can easily be adapted to raiding: due to the fact that the mast is quite back in the boat I don't think you can fit enough rowing positions. But I don't mind being corrected at all!

Best regards, Joost

Too create more space in the middle of the boat maybe an A-frame bipod mast attached to the gunwales could be considered? It could flop forward over the bow when not in use. I guess you could set a balanced lug inside it, attaching the downhaul to an eye in the bottom of the boat. The bipod would need to be stiff though so you could get decent downhaul tension -might be a prime candidate for carbon.

When I was droning on about sacrificing windward performance a few posts back this was one of the ideas I was kicking around - more windage than a single stick but boosted windward ability under oars. In fact I have sometimes wondered whether a decent (large) raid boat could be made from one of the transatlantic rowing boats by adding sail in this way - kind of like coming at the problem from the other direction.

I agree with Joost,

It is not meant as a raider at all, though we do have a rowing guy there as an artefact from the RAID41.

I'm not really interested in doing a specialist RAID boat. Would rather work out how to use the Goat Better. Keeps things simple and light and useful the rest of the time.

Mike wanted a big Australian Sharpie, I sorted moulded it in with where the OZ sharpie came from.

Australian Lightweight Sharpie
12sq m (heavyweight) Sharpie from ... um, maybe Germany?
A Fad of SharpiKreuzers in Germany and other countries between the two world wars - lake racing boats with restricted sail areas
American Sharpie.

In one of Howard Chapelles books there is a cool little sharpie from Europe ... designed or called the Stamfl Sharpie or something like that.

MIK and All,

This is a boat in "my character" - light and smooth (and easy to build)... a bit similar to 12 sqm sharpie class. I think boat by this idea could be speed in most of wind conditions (from light air to strong breeze) with experienced skipper nad crew.

Experienced is dead right!

Mmmm yep............this link shows the likely outcome when the breeze is up. http://www.mysailing.com.au/news/mor...ralian-sailing

I seem to recall doing much the same thing on the wire many years ago and the result was the same.

I think a 4' beam could be a little adventurous, I'm guessing the thinking is a single sheet for cost and ease of build, well I have been hoping Mik was thinking that far ahead.

A little plug for the photographer, Greg sure gets some great shots.

Nice spectacular photo's!!!

You will learn to handle her Mike. And if not, please ask Greg to be around with his camera!

Joost

I'll have to do some maths then! Are you thinking of using a trapeze or keep it body hiked?

MIK

No trapeze for me Mik. I may have inadvertently mislead you.

While a quick boat is desirable it needs to be much more sedate than a Sharpie to cater for my advancing years.

What about a sliding seat as an optional accessory? I'm thinking this could be made to work really well on this boat.

I thought Mik may have been heading down this track early in the piece these boats are also a hand full. Good thought I'd suggest fixed wings over hiking boards however. We must be mindful of keeping it light and easy to build which does limit some tricky bits.
