Hummmm! The fuselage is very small less than 5 cm2, and the added length multiplied by the added circumference is not that much… I might lose a few percent on top speed, but I was told someone has clocked more than 21 kts on the original LF foil… Hey, losing a few percent on 21 kts is not bad if I can get it to be more stable at 16kts….tkettlepoint wrote:longer will be easier to ride but will slow down the speed because of the wet surface area. But then if you start trying high AR wings you may gain some speed..

But I would like to check what is the stability you are looking for. As maybe your trouble is a yaw too free.
For that, it is more simple to add a vertical twin tip fin on the back of the fuselage.
Also, if your trouble is a too sensitive pitch, this is maybe due to a trimming of the AoA of the back wing you can do.
What is the target you are looking for.
How did your test in Florida, turn out ?meteo wrote: ...
I have since then made a 150%(910mm) and a 200% (1220mm) longer fuselage.. I have tried the 1220mm fuselage once, and to my surprise, it was so stable that I was able to jibe(change my feet) while on a foiling stance…
but the cold weather is here… and my test was only 30 minutes before I froze… going down to Florida this week to do more test…
How did your test in Florida, turn out ?
I'm curious what would happen to your 200% test ; if you reduced the size of the tail
proportionally to the increase in fuselage length ?
It should go faster ; and still be more stable , if when compared to different full scale
sailplanes, i have flown.
