The RAID41 Distance Cruising Racing Dinghy - discontinued

See bottom of page.
Discussion was on the Ubeaut Woodwork Forum

Original RAID41 website

RAID41 Cruising Racing DinghyThis was a promising boat, however many of the features intended to make it safer made it less safe.  The plan was discontinued.  See more information on the above woodwork forum link and the bottom of this page.

This is a boat design I am currently working on.   A single person distance racing/cruising boat. that can head away for a reasonable period, be fast enough around the buoys to be interesting or carry an extra person for daysails

There is a prototype on the way.  Once I know the hull goes together I will be close to releasing the plans.

I am hoping it will be light enough to get onto a car roof rack and narrow enough to fit inside a 4ft Box Trailer.

Originally it was conceived as an expedition sailing boat that was within the strength of one person on shore and on the water.  This creates quite severe restrictions on hull volume.  Wide powerful boats become very tiring when they have to be righted from capsize or dragged ashore by one person or rowed against a headwind.

An extra person was planned to be ok for daysailing or shorter cruises.

It is derived from my experiences with two of my flat bottomed boat designs.

The sailing canoe BETH and the Goat Island Skiff.

Goat Island Skiff Planing Gently

These two boats proved beyond the shadow of a doubt that a simplified hullform could be made to sail very quickly indeed upwind and down with very little fuss and no slamming into waves at all.  Videos.

So we took lessons about rocker, bottom shape and volume distribution from those and a number of other boats.

PDRacers saiil 200 miles along Texas coast in 5 daysOne of the other inspirations is a bit surprising.

My original thought about this boat was for RAID type events, but what I didn't understand is just how specialised and complex the boats have become and how hard the crews are working.

However there is another way to spend time.

Earlier this year three of the little box shaped PDRacers finished a gruelling sail for 200 miles up the coast of Texas over a 5 day period.

They are the three chaps in the pic - Andrew Linn, Jason Nabors and John Wright.  That's one of the Puddleducks (they were in separate boats)

Anyway ... they and everyone else had a great time travelling separately during the day but meeting up in the evenings to camp together.  I suspect the puddle duckers spent a lot more time sleeping than most with their 10 to 12 hours on the water each day.

First build of the RAID41 Expedition Cruising DinghyThe point is to participate.  So the thoughts of the OZ Woodwork group moved toward a cruising or expedition boat with the idea of something simple enough to build but faster than the PDRs.. Also with a self draining cockpit to save energy should one capsize.

The idea is to participate in a boat that is not a slouch, but not too much heavier or more complex to handle.  That can be rowed OK if necessary too.

Anyway ... point is ... the ideas were settled and they then pressured me to make good all my comments by putting something together.

So am working furiously on a plan that just seems to grow and grow.  The first prototype RAID41 is underway in the wilds of Scotland, built by the legendary Chris Perkins. (I threatened him with "legendary" inspired by some of the photos of his area)

Lyimington River Scows with lug rigsThe owner of the boat is Brian Pearson, who will club race out of Keyhaven in the UK (just past  the Western mouth of the Solent) and race to participate in a number of RAID type events.  

Brian has excellent technical knowledge of lug rigs because of weekly racing in the Lymington River Scow Class - pic right.  Even I learned a thing or two after years of professing to be some sort of expert!

The weaknesses of the RAID41 design



I discontinued the development because, while the boat sails very nicely, there were problems recovering from capsize.  The boat could be brought up from capsize but a single person would have trouble getting aboard again as the sides were too high to get over into the cockpit.

The prototype entered in the Texas 200 also sailed away from the sailor when it righted itself too quickly from capsize when he had released his hold on the boat and was stable enough upright to sail on without the sailor.  The boat was recovered later, but it was a lesson that features meant to make a boat safer actually worked in the opposite direction.  

There was some discussion that some types of boats would behave differently (eg, rounding up gracefully to be head to wind), but in 20 knot plus winds and the possibility of a sheet being cleated) or catching on something during recovery it is pretty hard to predict what any stable boat would do without someone aboard to steer it.

The main reason for dropping the plan was the capsize recovery.

The reason for this was the self draining cockpit design.  Because it raises the floor it means the sides of the boat have to be higher to allow enough space for rowing.  Boats without the rowing requirement could be lower sided.

Also as the boat quickly gets rid of any water from the cockpit it floats very high when brought upright.  I think a young and experienced sailor could mount the boat from the centreboard as the boat came upright ... but it would be too difficult for many older or less experienced sailors.

The other side was that the false floor added a great deal to the building - for a simple boat it took a long time to build.

So I have discontinued the plan.  I might derive something a bit different from the ideas of the RAID41.  But a long time away at the moment I think.
