Hi Oldmulti, This is my boat. The beams are very stiff and light and I'm surprised that more builders don't go this way. The pictures of the Tiki...
The mysteries of the Tohatsu alternator continue..... I installed a digital current/volt meter on a shunt and found that the alternator/charging...
OK - thanks.
I drilled a 5/8" hole on each side of the bulkhead to pass wiring. The holes are represented in the picture by the red dots. I wondered if the...
I have drilled holes in my stitch and glue boat's bulkheads to pass wiring. Is bulkhead strength significantly compromised by drilling holes...
Fascinating thanks. Is there a rule of thumb for this board area drag vs hull drag (I'm not good at math)?
For arguments sake, let's compare two boards with the same surface area: 1' chord and 6' span - 1.44" thick at 30% chord (NACA 0012) 2' chord and...
To expand on my question. I am assuming that the board will be a NACA 00 profile. My reading of posts on this site is that a low aspect foil is...
I know that a high aspect foil is the most efficient for fast boats, but what about slow boats? I am tinkering with a design for a dagger board...
In a canoe-sterned boat with the rudder extending from the stern. Calculating displacement speed, does the waterline length include the rudder,...
OK, I should chip in here as the original poster. I have become familiar with the idiosyncrasies of the Tohatsu charging over time and (sometimes)...
The outboard data in the "performance bulletins" is really interesting but is for planing hulls. You can see that the curves are affected by when...
I have a tohatsu sailpro 6hp powering my 1000 lb catamaran. At half throttle it does 6 knots in flat water, and 7 knots at full throttle. The...
This is amazing data, thank you Latestarter. You interpret it as being negligible improvement, but it strikes me that the difference in...
I just redid the center decks of my Tiki 21. They were 1/4 plywood/epoxy with stringers (no glass) and were very flexible. I redid them with 6 oz...
About 1" over 2 feet (0.5 inch per foot)
Hobby horsing, like windward ability, is another myth about Wharrams and vee hulls. When the rig is powered up, there is no hobby horsing, or...
Nice design. If it was 23 feet it would be my next boat.
Hi Guzzis3, I have the plans for my Tiki 21 and it is hard to imagine any way to make them simpler than they already are. I don't quite get your...
Hi Waterbear, Yes, Little Cat and I frequent that patch of water often. I heard a car horn one day - I wonder if that was you ;-) I am like most...
