Boost Motorized Fin to Sunfish Sailboat adapter - Lake Test
Вставка

- Boost surfing hasn't shipped me my "stick on" adapter yet, so I'm testing their electric surfboard & stand up paddle-board fin on my sunfish sailboat using a homemade adapter.
At the highest (110% for 20 second burst) setting, the Boost Fin was able to get my 14', 120lb sunfish hull up to 4 MPH. Running closer to 80% power in SUP "Wind" mode (the fastest continuous mode) I was cruising along at 3 MPH. [Not as good as under sail with a good wind, but a lot better than my speed sculling with no wind....]
I didn't test the battery life (because I broke my cedar board trying to yank it up away from some weeds while the boost fin was still pushing the far end forward....), but if the battery gauge built into the boost surfing mobile phone app can be trusted, it looks like I could have cruzed around for about an hour before the battery reached zero percent.
UPDATE: Range test video: • Boost electric surfing...
Looks like the battery capacity could do 30-40 minutes of range, BUT, it would shut down (due to overheating?) after only 14-18 minutes at a time. So if you limited things to shorter runs (3-5 minutes?) with cool-down time between them you might get 5-10 runs out of it

Well, the little electric motor is cute and all ... but this just gave me a great idea of how to install one of my many outboards on my little sailboat. Thanks!
Rudder pinions....pre-installed mount point. (Unfortunately the rudder cheeks are kinda expensive....)
Great idea! Just remember to have the charging port sealed! Silicone ear plugs work really well
I'm slightly less worried about that due to my freshwater, but I did check it when I got out of the water and it looked like the included plastic plug worked okay this time.
@@summetj A little Di-Electric Grease will do wonders. I use it on anything electrical I have outside
Great idea ,I will adapt it to my kayacat ,I think if the fin was 100% horizontal you would get more speed .
Very interesting application. Did you test the motorized fin in actual sailing conditions? My concern is whether the fin would hold up to the stresses on the rudder while sailing, particularly in a close hauled situation, where there would be significant lateral forces of water on the fin. If so, it would be great little boost for bring a sunfish into a traditional marina slip vrs. simply running it up on shore.
@@RobertFeucht I have not tested this under sail, as I do not think my first attempt at making a rudder attachment would be strong enough
thats pretty cool. I have a alcort sailfish mk2 i might try this with..
Wao, amazing idea.
2 years and still waiting for mine WTF boost where is my order

What's the model and price
This is the standard boost Fin but for this usage you would want to buy a their new larger battery pack Fin. They run in the 500 to $700 range.
That is awesome, however is your sunfish newer?! I saw a little inside area for storage?! Is that with the newer models or did you do that yourself?
The open storage compartment at the stern came with the boat.
@@summetj oh I love that! Mine does not have that but now I’m wanting to make one lol.
