g'day Makakilo
I hope you don't mind me butting in because I am not big, actually I'm little, but you have started a very interesting thread of general interest.
I have some questions which might help you or the other big guys with their advice. We know from the testimony of one of your comrades that you are very competent but we don't know how you want to surf these waves. You have been offered a variety of design ideas by the swaylocks members which favour different types of surfing.
You have already stated that it is for 0 - 4' (Hawaiian scale presumably). I've never been there, but would imagine the 1 or 2' Hawaiian that you have in mind can be fat (gently sloping), but not mushy (weak)? You will be surfing heavily textured (crosshore rippled waves) but not sloppy choppy, or you do want to handle this too?
Do you want to get close to the nimble/modern HP surfing? In which case you will want to resort to some quick rail to rail tactics to urge some extra speed out of the board in fat/slow sections. Will you want to resort to the slam the nose up and down tactic to get the board going when slowing? - ugly but effective and just about all the modern HPSB surfers on little boards do resort to this at times
Or do you want to do all your small/fat section surfing by using glide and for better sections on the wave surf only top to bottom with no double pumps?
You said that you didn't have much of an idea on bottom shape, but if you do want to use the rail to rail/double pump tactics then concave will help this. However in wide boards a double concave is better than a single concave and will handle chop and texture much better - the apex/stringer line of the double will cut through chop but the concave leading into the rails will give that rail to rail responsiveness at which the single concave excels - sort of get the best of both worlds. If handling powerful texture is a priority then a double concave set in a V will be even better at handling rough wave surfaces. The shaper of Strive surfboards in Santa Cruz CA told me that he has made Mavericks guns with a double concave.
In a HPSB the concave need not be deep to be effective - just 2 or 3 mm in a double makes a difference
If you do want to resort to the small wave tactic of slamming the nose up and down on a smallish (for your size) HPSB then a normal amount of rocker will help - I've noted that some of the offerings are very flat rocker and won't support this tactic so easily.
If you want to do the tight arc ripping then normal amounts of HPSB rocker will be better than the very flat rocker too.
Feraldave who posts here has a successful surfboard production business on the competetive Gold Coast and has worked out just how much volume an elite/pro surfer typically needs for their weight (0.35 multiplied by body weight in KG). So plugging in the numbers for your weight.
250 pounds = 113 kg
0.35 x 113 kg = 39.55 litres
You might be thinking that ah thats a pro formula and you are not pro, however I've heard it said on another forum by a blank CNC expert that big blokes frequently do use pro weight to volume ratios or even higher ratios. Looking at the ASP website of all the surfer profiles (including the women) does support this idea - the bigger the surfer the proportionally higher weight to surfboard size they generally ride.
so because you are bigger than the typical male pro then perfhaps a non-pro of your size could ride this ratio. Taking a somewhat random look at a modern example of a high volume HPSB Al Merricks measurements for the Flyer 1 are conveniently available, so thats why I'm choosing this - the closest one comes in at 45 litres which would have some volume to spare on the above calculation - its narrower than what you have in mind and probably looks more like a scaled up HPSB than what you have been sort of suggesting, although this board even in its 6' form is a bit wider and chunkier than a normal HPSB.
6' 8"
Nose 12", M 20.5" Tail width 15"
thickness 2.88 "
volume 45 L.
5.63 inches and tail rocker is 2.16 inches which means its a highish nose rocker and lowish tail rocker board - although the opposite type of rocker also works well but is different. I just thought you might like to know these numbers.
I don't have rocker measurements for this flyer 1, but I do have rocker measurements for the 6' 6" Flyer II, the nose is
I don't mean to try and tell you what you should be riding, just thought I'd throw a few numbers in as food for thought and as I mentioned this thread is very interesting so would enjoy reading your response on what the waves are like and how you want to ride them.
It could be that you get a strong feeling that such a board as described is not big enough despite crunching the numbers?
Like has already been said, thin/normal rails with a domed deck and thick along the stringer line is a good way of getting extra volume without rail corkyness - although I am small I have ridden boards with this combination of features.
