MilesH, hope its helps your decision. These comments relate to me, others with a different skill-set may disagree.
Let's discuss board sizes re. body weight, the foil type, your usual water state ( surf or flat) and the wind strength considered normal in your area. HA foils need more initial board speed.
In my experience there seem to be some general guides,
my body weight 74kg.
Board volume...For kneel starts plus10 to minus 10 of body weight is more stable than 20 plus.
starts in the lightest wind more board length and + 35 is an advantage . More volume than that becomes too corky.
Wing.+ 15kt 85 L. x 5'2" x 25" . (fanatic 2023)
Sub 15kt. 105 L. x 7'3" x 28". (jimmy lewis 2016 ish )
both conventional Hawaii designed boards like Naish.
prone / Downwind 95 L. 6' 3" x 21 1/2". Similar to DK.( next board will be much longer and 105 L. )
prone/ Tow 34 L. 4'8" x 18". Similar to Amos. ( very happy with this board)
re.designing; Length width and rocker profile play a huge part in getting to initial foil speed.
The Wing boards designed in Hawaii tend to have a lot of rocker, thats good for them ! they have lots of wind so starting is not an issue. Not so good where I live. Still lots of people on Naish's moderate boards though. I like them because they are thin in the rail.
Downwind boards are straighter and flatter and thats good for getting up with little power and coaxing HA foils up to speed.
A lot depends on your personal criteria, my self I don't like trying to stand on corky boards at taxi speed.
My Current light wind board is a five year old early Jimmy Lewis Hover105 Ive converted from Tuttle to track plate. It has a flat bottom no chines and a gentle rocker. The thin rails are submerged at rest with me standing. Its stable like that.
The 5'2" 85l Fanatic has big boxy rails that are almost submerged with me kneeling to start its stable athwarthships but critical fore and aft. You have to be kneeling just right and getting to my feet without upsetting the balace took some training at first. (I'm 70y gym work is mandatory) however well worth the effort because in the air the low swing weight is a treat. It also comes up off the water easily because of the uncomplicated bottom shape.
And of couse the tow board is fully submerged to my Chest/ waist pre start.
I think the biggest disadvantage in choppy water is over bouyancy and in still water its too much rocker.
Re foil type. HA foils need more initial board speed so width and rocker play an important part if theres not adequate wind.
Re Naish boards, I recently checked out their new race board with two stage rocker. Short and wide with a big transition in the middle of the rocker. As a general use board it has some disadvantages. A gentle even shallow rocker is more use. .
(just to sum up, there's a 'buoyancy point' below and above body wt that does not work.
Over 35 gets corky.
For standing sinker starts higher than minus 40 is too buoyant for me.)
MilesH you could go no more than + 10 your body weight and be comfortable if theres enough wind to taxi kneeling. Standing up from your knees in a gust should be easily doable with practice. More buoyant than that and your skill progress will out grow it quickly.
Keep your big board for marginal days.
Cheers, chris.
Thanks Chris, really appreciate the detailed reply and the time it must have taken to write that. Really useful :)
Thanks all, based on the above comments I'm going to go for the 95l Carbon Ultra. I am predominantly on HA foils at the moment and light wind days are regular throughout the year, so I want to maintain a bit of float.
Think I need to start learning the stingbug though in preparation for future purchases :)
