Last Saturday I was invited to a Stag do at a local Pub. Over the past couple of years I have rarely entered such establishments as the thought of a hangover coupled with what amounts to a pretty good waste of money has put me off.
What I hadn't realised was that I really missed chatting and discussing sailing with like minded friends. I didn't drink too much and I was definitely in the minority. A friend of mine stopped slurring at around 22.30hrs because the slur had developed into an inaudible dialect. However, just before this inevitable occurrence we discussed yacht designs and that ugly looking but surprisingly fast new sscrrooooowwww design! I honestly couldn't make out the name of the design due to the slurred speech and yet I knew exactly which design he was referring to.
Well, since last Saturday I've been giving the scow bow a lot of thought and despite it being dog ugly there must be some mileage in the concept.
Would, could this be developed for IOM's? I guess the only way to tell is to have a go. What can go wrong...........(lots) well as I see it from a non expert, complete novice perspective the design will have a LWL of less than 1m. My current design has a LWL of roughly 930mm but the wetted hull area of the bow will be increased by over 100%. This in turn should allow me to reduce the freeboard without affecting the reserve buoyancy. Upwind due to the LWL and the relationship between the bow and hull center line, pointing and speed in normal conditions could be compromised. But perhaps the downwind advantages will more than make up for the cons. I reckon this bow will rarely if ever bury, couple this with a fairly neutral longitudinal trim should provide an excellant foundation for the rig to work off.
Perhaps, changing down a rig will no longer be so dependant on loss of downwind yacht control?
It was sunny, fairly warm and a light breeze. Best of all I had finished work by 11.30 text a friend and we were both sloping by 13.00
I took the SAS Wildthing 60" and 78" Svenson Sunny 2ch glider which hadn't been one of my favoured models. However, a recent bit of tweaking and she was like a different glider. Sunny was proving to be a pleasure to fly and I love the retro 70's feel about her, combine this with just 2 channels the flying was very rewarding (I never thought I'd say that)
Rebound is 99% complete. I just need to make the final control rod attachments and do a bit more whistling, current forecast is >5mph tomorrow. I've taken a guess at the CoG and balanced she comes in at 655 grams (l.4lbs)
44" of symmetrical wing and over proportioned control surfaces she could be a hoot

The gliders are starting to come out of hibernation, yesterday the P15 took to the sky and the lift and my skill was a little bumpy at times. Then today I had a little hour to spare and decided to take the Svenson Sunny to my local slope. This glider really does have a mind of it's own but for some reason despite others slating this model (which I can understand) I really enjoy the challenge of flying her. Next time out I'm going to take some nose weight out as in a dive test she climbs out fairly quickly and whilst under normal flight I'm constantly pushing the nose down.
I shot a short film in very light conditions yesterday. VMG will probably be measured the week after next and seeing her sail in near drifting conditions will help me decide where to place the corrector weights if required
It's now 4 months since I sketched the plans and Rebound still isn't finished. This is mainly due to the little matter of designing and building VMG a RC IOM racing yacht in the meantime. Now that VMG is afloat I have Rebound to complete, then the Solange and Topaz kits should see me through the Summer soaring season.
If I can get some spare funds I might even treat myself to an elec thermal glider
Last Sunday was her first race since a repair to the hull. The conditions were just right 8-10 mph. I had some good starts and she was pretty well balanced going uphill. Her bow appeared to have more than adequate buoyancy on this point of sailing but whilst going downhill there seemed to be less buoyancy !!
Overall I was very pleased with her performance and finished with my lowest score since I've been racing IOM's
